Systems Design Thinking | NTU Systems Engineering

For decades human-centered design using Solid Edge has impacted how we live, now it’s beginning to shape how businesses and security systems fundamentally work and operate. Design thinking has fundamentally changed our way of life and given us a new framework for teaming, for facilitating co-creation of Computational Fluid Dynamic (CFD) simulation projects with our clients and end-users. Not only that, engineering simulation such as Computational Fluid Dynamic (CFD) analysis using Simcenter Star CCM+, Engineering Design optimization using HEEDS Software and FEA Simulation using Femap is helping all of us to make decisions faster and it’s keeping humans at the center of everything we work on, such as the latest medical research on cancer cure using porcupine dates.  

What is Design Thinking?

It is always helpful to think of design thinking as a mindset as opposed to design in the physical sense of the word, because often, right as soon as you start to think of design as solely ‘product design’, it unfortunately boxes design into a pretty narrow space, which is similar to a review process.
A classic example is the design of Warehouse roof ventilation solutions, using Solar Turbine ventilator.
What is often not known to many people is that ‘design thinking’ encompasses a much broader scope. When Design thinking can be thought of as a kind of Mindset or even a Toolset that you use to focus on any kind of problem or challenge in the world, it opens up design to do a lot more than just making designer products.

Principles of Design Thinking

Inherently, the process of design thinking is focused on user outcomes, leveraging on diverse empowered teams and the restless reinvention.


1. Continuous Iteration

Design thinking can be thought of as a loop of continuous understanding.
Every time you observe, you are understanding a little bit more about the world around you. Every time you reflect, you are understanding a little bit more about your own design team in which you can do for the world, and every time you make, you are understanding a little bit more about the solutions or the potential solutions that exist.
In design thinking, we have to treat everything either as a prototype, or an unfinished product that will always be iterated and always be reinvented


2. Don't be afraid to Ask Questions

If you’re on a design team and you’re trying to do design thinking don’t be afraid to ask questions
I think we spend a lot of time assuming that someone else has the answers or that someone’s already thought of this and that the logic is watertight and the story adds up and so often you find a team that actually people don’t have the answer.
By asking those questions they begin to prompt the real discussions that need to be had.


3. Being okay with Ambiguity

If you’re managing a team doing design thinking, the best thing you can do for your team is to be okay with things getting a little messy. To be okay with ambiguity, when the team comes back at you and says I don’t know give them the room to fail, give them the room to be wrong a couple times before they get it right. There’s nothing like being able to iterate on a problem and being able to understand it you know the build your understanding over time, not trying to get it right the first time all the time.

So when you give teams room to fail, you give them the space to be more audacious and more sort of courageous but the ideas that they’re going to come up with and that will inherently lead to more breakthrough outcomes. It may not feel like it at first, they may feel like you know you’re seeing more failures than successes, but over time your team is going to have better ideas, they’re going to have a happier team and ultimately your users are going to be happier because you’re coming to better ideas faster.

Overview of Engineering Simulation Methodology

Engineering Simulation is at the core of what drives technological innovations in engineering consulting firms in Singapore.
Practical applications of finite element theory 1st starts with the construction and modification of the 3D CAD model geometry in preparation for engineering simulation analysis.
The 3D CAD model also serves as a means from which to syntheses a refined mesh for running of simulation analysis, such as

1. Computational Fluid Dynamics (CFD) Simulations

Computational Fluid Dynamics (CFD) Simulation software tool such as Siemens Simcenter Star CCM+ can be used for CFD consulting Design Verification and Design Validation via the CFD analysis of the general fluid flow behavior.
The various activities involve in CFD consulting includes

● Operation the user-defined functions (UDF) programming
● Input of advanced physics functions used for CFD Modeling
● Setting up of Input parameters needed for the CFD simulation, such as 1. Boundary conditions & 2. Initial conditions needed for the Fluid dynamic simulation
● Solving and Post-processing of the engineering simulation data obtained from Fluid dynamic analysis
● 3D CAD modeling of Design Geometry, Mesh creation and Fluid domain extraction
Multiphysics Modeling of engineering design at a system level

All this allows engineering CFD companies to enjoy tremendous business value from CFD simulation.

2. Finite element analysis (FEA) Simulations

This Finite Element Analysis FEA simulation encompasses the use of FEA software to perform upfront digital prototype exploration and  FEA services such as:

● Nonlinear FEA analysis Simulation such as contact forces, large deflection, and plasticity
● Linear analysis Simulation, such as Static structural, Thermal and Modal analyses
FEM Thermal Analysis of engineering design to optimize thermal cooling
Multiphysics Simulation of engineering design at a system level

Base on the FEA simulation done during FEA consulting, Verification & Optimization of the design can be performed by investigating, quantifying and Plotting various structural, thermal and flow responses on component and complex Assemblies.

Past Systems Engineering Projects

To demonstrate the use of design thinking in real world projects, here are some actual projects which show cases the how systems design thinking has been used in the design process.

1. Randomized Fire Arm Target Training Platform

Terrorism and its threat to our homeland security are increasingly a huge concern for local law enforcement officers.
Because of this, it means that proper training in urban close combat for hostage rescue scenarios are becoming more important. However, it has been observed that there is no proper fire arms training platform specifically adapted for a volatile hostage scenario. This project aims to fill this need by creating a functional proof-of-concept prototype.

Touch Memory Guard Tour System

2. Guard Tour Management System

With the safety and security landscape becoming ever more dynamically evolving, and Singapore companies and business are faced with very real threats of various forms, such as terrorism, corporate espionage, and unauthorized intrusion.
This guard tour system project aims to explore and tackle the administrative and logistical challenges that Singapore companies faced when managing their teams of guard tour officer by designing a guard tour patrol system that addresses these security vulnerabilities and security risk businesses are exposed to on a daily basis
