Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inertial measurement unit uses a fixed integrated structure, then the device structure is simple, but the extensibility and adaptability to different user demands are poor
Solution Approach 1:
The inertial measurement unit is divided into separate functional modules: a sensor unit containing inertial sensors and a substrate unit containing processing and display units. These modules can be detachably connected via fixing members, allowing the system to be segmented for flexibility while maintaining simplicity when assembled. This segmentation enables different configurations for different user needs without requiring a completely different device structure.
Solution Approach 2:
The fixing members are designed to be removably attachable, allowing the configuration of the inertial measurement unit to change dynamically. Users can attach or detach the sensor unit from the substrate unit based on specific measurement needs, transforming the device from a static integrated structure to a dynamic reconfigurable system that adapts to different operational requirements.
2Ease of operation
If the inertial measurement unit processes and displays data internally, then user-friendliness improves, but device complexity increases
Solution Approach 1:
The processing unit and display unit are integrated into the substrate unit, which can be detachably connected to the sensor unit. This merging of data processing and display functions within the same module eliminates the need for external devices, improving user-friendliness by providing all functions in one portable unit while keeping the overall device complexity manageable through modular design.
3Measurement precision
If the sensor unit and substrate are firmly fixed, then measurement accuracy improves, but the ability to reconfigure for different users is reduced
Solution Approach 1:
The fixing members are pre-designed with specific attachment mechanisms that ensure proper alignment and firm connection between the sensor unit and substrate unit when assembled. This preliminary design of the attachment structure allows users to easily achieve accurate measurements through simple attachment actions without requiring complex adjustment procedures, while still maintaining the ability to detach and reconfigure for different users.
