Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sensors are placed on the surface of the insole, then sensor wear occurs and user comfort deteriorates, but if sensors are embedded in the insole interlayer, then manufacturing complexity increases
Solution Approach 1:
The pressure sensing layer is embedded within the insole structure, with the sensing layer positioned between the upper and lower layers of the insole. This nested configuration protects the sensors from external wear and damage while maintaining user comfort, as the sensors are integrated into the insole matrix rather than exposed on the surface.
2Ease of manufacture
If sensors are configured randomly on the insole, then manufacturing is simplified, but data capture accuracy at key locations deteriorates
Solution Approach 1:
The pressure sensing layer includes strategically positioned sensing regions corresponding to key foot pressure areas such as the heel, metatarsal heads, and toe regions. This localized configuration ensures accurate capture of pressure data at critical locations while maintaining a relatively simple overall manufacturing process through standardized layer integration.
3Reliability
If individual sensors are used with separate devices, then sensing functionality is achieved, but mass production efficiency and cost-effectiveness deteriorate
Solution Approach 1:
Multiple pressure sensing elements are integrated into a single unified pressure sensing layer that is embedded in the insole. This merged configuration allows the entire sensing system to be manufactured as one integrated component rather than assembling multiple individual sensor devices, thereby improving mass production efficiency and reducing costs while maintaining reliable pressure sensing functionality across the entire insole surface.

AI summary
The present invention discloses a smart sensing insole including a pressure sensing layer (for instance a pressure plate) which includes sensing sensors. The sensors are used as sensing points to measure the pressure and the distribution when the foot pressure changes. Each sensor is coupled to the sensing module. The area occupied by the sensing points is between 3-50% or 3-70% of the entire insole area. The sensing point position is configurated at pressure peak position, pressure center area, foot arch position.
