Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ultrasonic and x-ray inspection techniques are used to measure drill wander, then measurement capability is provided, but inspection time increases and subjectivity remains
Solution Approach 1:
The patent extracts the measurement function from complex inspection equipment (ultrasonic/x-ray devices) and implements it through a simple visual inspection method using the toothed trough structure. The trough teeth serve as reference markers that allow direct visual measurement of drill wander, eliminating the need for time-consuming specialized inspection equipment.
Solution Approach 2:
The cold plate structure itself provides the measurement reference system through the toothed trough configuration. The trough teeth are integrated into the cold plate body, serving dual purposes: structural support and measurement reference markers. This self-service approach eliminates the need for external inspection equipment and procedures.
2Adaptability or versatility
If multiple separate components are used to create fluid passages, then manufacturing flexibility is improved, but assembly complexity and parts count increase
Solution Approach 1:
The patent merges multiple separate components (individual passage elements, connectors, and closures) into a single monolithic cold plate structure. The toothed trough configuration allows multiple parallel passages to be created within one integrated body, eliminating the need for separate components and reducing assembly complexity while maintaining manufacturing flexibility.
