Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single form factor is used for wearable devices, then device simplicity and manufacturing ease are maintained, but adaptability to different use scenarios and user comfort are compromised
Solution Approach 1:
The wearable device is divided into multiple independent modules including a head-mounted display unit, supplemental units with connectors, and interchangeable straps. Each module can be independently configured and assembled based on specific use scenarios, allowing the system to adapt to different requirements without increasing overall system complexity.
Solution Approach 2:
The device employs universal connectors and standardized interfaces that allow the same base unit to work with multiple different supplemental units and strap configurations. This multi-functionality enables a single core device to serve various purposes across different use scenarios while maintaining simple manufacturing processes.
2Weight of moving object
If all functional components are integrated into a single unit, then device reliability is improved, but weight distribution and user comfort deteriorate
Solution Approach 1:
Functional components are segmented into separate modules (head-mounted display, supplemental units, straps) that can be independently optimized for weight. This segmentation allows weight to be distributed across different body parts rather than concentrated in one location, improving comfort while maintaining reliability through standardized connection interfaces.
Solution Approach 2:
Universal connectors serve as intermediaries between modules, ensuring reliable electrical and mechanical connections while allowing flexible assembly and disassembly. These standardized interfaces maintain connection reliability even as modules are reconfigured for different weight distribution scenarios.
3Adaptability or versatility
If modular components with multiple connectors are used, then adaptability to different configurations is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Standardized universal connectors are designed to work across all modules, allowing the same connector design to be reused throughout the product line. This universality simplifies manufacturing by reducing the variety of unique parts that must be produced, while still enabling high configuration flexibility through different module combinations.
Solution Approach 2:
The connector design incorporates adjustable parameters such as connection orientation and engagement force to accommodate different assembly requirements. This allows a single connector type to be manufactured with consistent specifications while adapting to various assembly scenarios, maintaining manufacturing simplicity.
