Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional modularized flexible electronic blocks are assembled with predetermined size, arrangement position, and arrangement shape, then manufacturing efficiency is improved, but customization capability to match body characteristics deteriorates
Solution Approach 1:
The device is divided into multiple detachable electronic blocks that can be independently manufactured with standard specifications and then selectively assembled. Each electronic block functions as an independent module that can be attached or detached from the wearable substrate, enabling both efficient standardized manufacturing and flexible customization by selecting different combinations of blocks for different users.
2Strength
If electronic elements and circuits are formed with high Young's moduli, then structural strength is improved, but flexibility and resistance to external deformation deteriorates
Solution Approach 1:
The patent employs flexible substrates and thin film structures for the wearable device base and electronic block enclosures. These flexible shells allow the device to conform to irregular body surfaces and withstand external deformation while protecting the internal electronic components. The flexible substrate material enables the device to maintain structural integrity during stretching and bending without breaking the electronic elements.
3Ease of operation
If the wearable device is designed to fit irregularly curved surfaces, then wearability is improved, but manufacturing complexity increases
Solution Approach 1:
The wearable device is segmented into a flexible substrate base and multiple detachable electronic blocks. The substrate can be manufactured as a simple flexible form that conforms to body contours, while the electronic blocks are standardized modules. This segmentation allows the complex fitting requirement to be satisfied by the flexible substrate alone, while the electronic blocks maintain simple standardized manufacturing processes.
Solution Approach 2:
The flexible substrate is designed as a universal base that can accommodate different combinations of electronic blocks and adapt to various body shapes and sizes. This universal design allows a single substrate type to serve multiple customization configurations, reducing the need to manufacture different substrate variants for different users.
