Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If current wearable wireless device architecture is used with wired connections to hub/basestation, then data transmission to remote servers is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the cellular modem functionality from the external hub/basestation infrastructure and integrates it directly into the wearable device itself. This allows the device to independently transmit data to remote servers via cellular networks, eliminating the need for complex wired connections to intermediate hubs and reducing overall system complexity while maintaining manufacturing feasibility
Solution Approach 2:
The wearable device incorporates a universal cellular communication capability that enables direct wireless connection to cellular networks for data transmission. This multi-functional approach allows the device to operate independently without requiring specialized wired infrastructure, simplifying both the device architecture and manufacturing process
2Reliability
If adhesive portions are used to secure wearable device to skin, then device attachment is achieved, but user comfort deteriorates
Solution Approach 1:
The patent applies different adhesive compositions to different regions of the adhesive portion. The first adhesive layer provides strong bonding to secure the device to the skin, while the second adhesive layer, applied selectively around the perimeter, provides additional edge support without excessive skin contact. This localized variation in adhesive properties maintains reliable attachment while reducing overall user discomfort
Solution Approach 2:
The adhesive portion utilizes a composite adhesive structure with two distinct adhesive layers having different formulations and properties. This composite approach combines the benefits of strong bonding with reduced skin irritation, achieving both reliable device attachment and improved user comfort through material composition optimization
3Ease of operation
If reusable component with cellular chipset is used, then wireless communication capability is improved, but device cost increases
Solution Approach 1:
The patent divides the wearable device into reusable and disposable components. The expensive cellular chipset and wireless communication hardware are contained within the reusable component that can be reused across multiple disposable adhesive portions. This segmentation allows the high-cost wireless communication capability to be amortized over multiple uses, reducing the effective cost per use while maintaining full wireless functionality
