Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple electronic parts are mounted separately in the cockpit, then each part can be connected to its connector through main cable, but this leads to increased cable length, excessive material costs, and weight
Solution Approach 1:
Multiple separate electronic parts are merged into a single integrated electronic device with a unified housing and shared connector, eliminating the need for multiple separate cables and reducing overall cable length and weight
Solution Approach 2:
The single connector on the electronic device serves multiple functions by providing electrical connections to all necessary vehicle systems (display, audio, communication, etc.) through one universal interface
2Temperature
If heat dissipation components (heat sinks, fans) are added to cool electronic parts, then high-temperature operation performance is secured, but this increases weight, causes noise problems, and increases cost
Solution Approach 1:
The mechanical cooling system (heat sinks and fans) is replaced with a liquid cooling system that uses a coolant circulating through channels in the housing to dissipate heat, eliminating moving parts and associated noise and weight
Solution Approach 2:
A liquid coolant is used to transfer heat away from electronic components through hydraulic circulation, providing efficient cooling without the need for mechanical fans or heavy heat sink structures
3Adaptability or versatility
If electronic parts are distributed in various places in the cockpit, then each part can be independently connected, but this increases cable length and material costs
Solution Approach 1:
Multiple distributed electronic parts are combined into a single integrated unit, reducing the total quantity of cable material needed while maintaining all necessary connection capabilities through one connector
