Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traffic signalling pole uses a simple cylindrical pole part with a disc-type base part made of synthetic material, then the device can be produced with reduced cost and simplified manufacturing, but the fixation to the pavement becomes unreliable and complex to install
Solution Approach 1:
The pole is divided into a pole part and a base part that can be assembled together. The base part includes multiple fixation elements that can be independently adjusted and positioned, allowing reliable fixation to the pavement while maintaining simple manufacturing of each individual component
Solution Approach 2:
The base part incorporates adjustable fixation elements that can be positioned and locked at different locations. This dynamic adjustment capability allows the fixation system to adapt to different pavement conditions and installation requirements, providing reliable fixation without complex manufacturing
2Reliability
If a traffic signalling pole uses traditional fixation methods, then the pole can be retained on the pavement, but the installation process becomes laborious and time-consuming
Solution Approach 1:
The base part is pre-assembled with multiple fixation elements in specific positions before installation. This preliminary preparation allows for quick installation on-site, reducing installation time while maintaining reliable fixation retention through the pre-positioned fixation elements
Solution Approach 2:
The fixation elements are designed to be self-aligning and self-locking into the pavement. Once positioned, the elements automatically secure the pole without requiring complex manual adjustment or additional tools, significantly reducing installation time while ensuring reliable retention
3Stability of the object's composition
If a traffic signalling pole uses a fixed rigid structure, then the pole provides stable signalling, but the pole cannot recover its initial shape after being hit by a vehicle
Solution Approach 1:
The pole part is designed with controlled flexibility that allows it to bend and deform under impact forces, then return to its original position. This parameter change in rigidity enables the pole to absorb impact energy while maintaining overall structural stability for continued signalling function
Solution Approach 2:
The pole structure incorporates dynamic characteristics that allow it to flex and move in response to external forces such as vehicle impacts. This dynamic behavior enables the pole to recover its initial shape after deformation, providing both stability during normal operation and adaptability during impact events
