Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a dedicated inspection device for cooling plates is not provided, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The inspection device is divided into multiple functional modules: support blocks for positioning, gauge jigs for distance measurement, gauge grooves for flatness measurement, and clamps for securing the cooling plate. Each module performs a specific inspection function, allowing the system to achieve high measurement precision through specialized components rather than a monolithic complex device.
Solution Approach 2:
Gauge jigs and gauge grooves serve as intermediary measurement tools that bridge the cooling plate and the measurement system. The gauge jigs measure distances from reference surfaces to specific points on the cooling plate, while gauge grooves assess flatness, enabling accurate defect detection without requiring a single complex inspection device.
2Measurement precision
If multiple measurement points are used to inspect cooling plates, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The support blocks and clamps serve multiple functions: they position the cooling plate, secure it during inspection, and provide reference surfaces for measurement. The gauge jigs can measure multiple distances from different reference points, and gauge grooves can assess flatness at various locations, allowing multiple measurement points to be inspected using a unified modular system rather than requiring separate complex devices for each measurement location.
