Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the platform is designed with sufficient thickness and strength to support testing operations, then structural strength is improved, but the platform becomes vulnerable to damage when vehicles drive over it during collision testing
Solution Approach 1:
The platform is divided into distinct functional zones: a mounting area with reduced thickness for vehicle passage and an installation area with sufficient thickness for housing functional elements. This segmentation allows the platform to accommodate both structural requirements and collision testing requirements without compromising either.
Solution Approach 2:
Different regions of the platform are assigned different thickness characteristics tailored to their specific functions. The mounting area features reduced thickness to enable undamaged vehicle passage, while the installation area maintains sufficient thickness for structural support and component housing, optimizing overall platform performance.
2Ease of operation
If the base body is made thin to allow vehicle passage, then ease of operation is improved, but structural strength deteriorates
Solution Approach 1:
The base body is segmented into a thin mounting area for vehicle passage and a thicker installation area for structural support. This segmentation enables the platform to provide both ease of operation for vehicle passage and sufficient structural strength where needed.
Solution Approach 2:
The base body exhibits local quality variations in thickness: thin in the mounting area to facilitate vehicle passage and thick in the installation area to provide structural strength. This localized differentiation resolves the contradiction between ease of operation and structural integrity.
3Adaptability or versatility
If functional elements are installed in the platform, then device functionality is improved, but the platform thickness increases, preventing undamaged vehicle passage
Solution Approach 1:
The platform is segmented into a mounting area without functional elements for vehicle passage and an installation area containing functional elements. This segmentation allows the platform to provide full functionality while maintaining a thin profile in the critical vehicle passage zone.
Solution Approach 2:
Functional elements are localized to the installation area, allowing the mounting area to remain thin for vehicle passage. This spatial differentiation of functionality resolves the contradiction between device versatility and platform thickness.
4Strength
If the platform structure is reinforced to prevent damage, then structural strength is improved, but measurement precision deteriorates due to increased thickness affecting sensor readings
Solution Approach 1:
The platform is segmented into a thin mounting area for accurate sensor measurements and a reinforced installation area for structural strength. This segmentation allows the mounting area to provide measurement precision while the installation area provides structural robustness.
Solution Approach 2:
The platform exhibits local quality differentiation: the mounting area maintains thinness for measurement precision while the installation area provides reinforcement for structural strength. This localized optimization resolves the contradiction between robustness and measurement accuracy.
