Solution Overview
Problem
Wearable devices often suffer from inaccurate data measurements due to structural issues that cause gaps between sensors and skin, leading to noise in physiological data signals and increased power consumption, while also lacking durability and personalization.
Innovation Solution
A wearable ring device with a comfort dome design featuring a flat or slightly curved inner circumference and interchangeable outer housing, which ensures secure fit and improved skin contact, reducing noise in data signals and allowing for customizable aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wearable device structures are used, then manufacturing is simpler, but gaps between sensors and skin cause inaccurate data measurements
Solution Approach 1:
The patent applies curvature by designing the inner circumference of the wearable device with a flat or slightly curved surface that conforms to the finger contour. This curved design eliminates gaps between the sensor and skin, improving measurement accuracy while maintaining manufacturing feasibility through standard molding processes.
Solution Approach 2:
The patent implements local quality by creating a differentiated structure where only the inner circumferential surface contacting the skin is flattened or curved, while the outer housing maintains its structural integrity. This localized modification improves sensor contact without requiring complete structural redesign.
2Reliability
If durable materials and construction are used, then device durability increases, but manufacturing cost and complexity increase
Solution Approach 1:
The patent divides the wearable device into separate modules including the outer housing, inner housing, and sensor assembly. This segmentation allows each component to be manufactured independently using optimized processes, then assembled together, improving both durability through specialized materials and manufacturing efficiency through modular production.
Solution Approach 2:
The patent employs nesting by placing the inner housing containing sensors within the outer housing. This nested structure provides protective layers that enhance durability while maintaining a compact form factor that simplifies assembly and manufacturing processes.
3Adaptability or versatility
If fixed design structure is used, then manufacturing is more efficient, but personalization and customization are limited
Solution Approach 1:
The patent applies dynamics by making the outer housing removable and replaceable, allowing the device to adapt to different user preferences. The modular design enables easy swapping of outer housings with different aesthetics while maintaining the core functional components, providing personalization without complicating the base manufacturing process.
Solution Approach 2:
The patent implements universality by designing a standardized interface between the inner housing and outer housing that works across different variants. This universal connection method allows multiple outer housing designs to work with the same core device, enabling personalization while maintaining manufacturing efficiency through shared components.
