Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional optical measuring units are used with separate housing components, then the device structure is easier to manufacture, but the overall device size becomes bulky and complex
Solution Approach 1:
The patent merges the housing structure with the reflector function by integrating a hollow reflector directly into the housing. This combines multiple components (housing + reflector) into a single integrated structure, reducing overall device volume and simplifying the structural design while maintaining the necessary optical measurement functions
Solution Approach 2:
The hollow reflector serves multiple functions simultaneously: it acts as both the housing structure and the optical reflector, and also provides integration space for the radiation source and sensor. This multi-functionality reduces the number of separate components needed, thereby reducing device volume and structural complexity
2Adaptability or versatility
If multiple measuring functions (oximetry, EKG, bioimpedance) are integrated into a single device, then diagnostic capabilities are enhanced, but the device structure becomes more complex and costly to produce
Solution Approach 1:
The patent combines multiple diagnostic measuring functions (optical oximetry, EKG, and bioelectrical impedance measurement) into a single integrated device with a unified housing structure. This merging of functions into one device enhances versatility while the integrated design helps manage structural complexity through shared components
Solution Approach 2:
The device is designed as a universal measuring unit that can perform multiple diagnostic functions simultaneously or sequentially. The hollow reflector housing accommodates different sensor types (optical, electrical) within a single structure, enabling multi-functional operation without requiring separate devices for each measurement type
