Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shoes lack the capability to maximize sensing sensitivity and generate calculation values based on sensing data to match and display motion images with time effectively.
Innovation Solution
A shoe design incorporating a sensing system with multiple sensors embedded in the outsole, including a first sensor for the forefoot area, a second sensor for the rear foot area, and a third sensor positioned deeper, communicating with a control module that processes data to generate calculation values and display motion images alongside these values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are embedded at different depths in the outsole, then sensing sensitivity is improved, but device complexity increases
Solution Approach 1:
The sensing system is segmented into multiple sensors positioned at different depths within the outsole structure. Each sensor segment targets specific pressure zones (forefoot, midfoot, rearfoot) to capture detailed foot pressure distribution data, thereby improving measurement precision without requiring a single complex sensor system
Solution Approach 2:
The patent transitions from a single-plane sensor arrangement to a three-dimensional multi-depth sensor configuration. By embedding sensors at varying depths (first sensor at depth d1, second sensor at depth d2 where d2 > d1), the system captures pressure information across vertical dimensions, enhancing sensing sensitivity to detect subtle pressure variations that single-depth sensors would miss
2Measurement precision
If sensors are embedded deeper in the outsole, then pressure distribution measurement accuracy is improved, but manufacturing precision requirements increase
Solution Approach 1:
Different regions of the outsole are equipped with sensors at locally optimized depths. The first sensor is positioned at depth d1 in the forefoot/midfoot area while the second sensor is positioned at greater depth d2 in the rearfoot area, allowing each region to be measured with appropriate sensor placement that accounts for local pressure distribution characteristics
Solution Approach 2:
The sensor embedding depths are predetermined and pre-configured during the outsole manufacturing process. By establishing the depth hierarchy (d2 > d1) as an inherent feature of the outsole structure rather than requiring post-manufacturing adjustment, the system achieves accurate pressure measurement while managing manufacturing precision requirements through integrated design
