Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of smart shoes face difficulties in determining whether sensors are operating and accurately connecting to a user terminal, especially when multiple smart shoes are present, and there is a lack of real-time feedback for exercise correction.
Innovation Solution
The solution involves an insole with pressure sensors and a tactile element that vibrates upon command, allowing for pairing with a user terminal through vibration detection, and providing exercise feedback by calculating the center of gravity and comparing it to exercise reference areas to adjust vibration patterns accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple smart shoes are present around the user, then the user terminal may have difficulty determining which sensor to connect to, but the patent implements a vibration feedback mechanism that enables accurate and quick connection to the correct insole
Solution Approach 1:
The patent implements a feedback mechanism where the user terminal sends a vibration command to the target insole, and the insole's tactile element vibrates in response. The user terminal detects this vibration through its vibration detection sensor, confirming accurate identification and connection. This closed-loop feedback system resolves the ambiguity of connecting to the correct insole among multiple devices.
Solution Approach 2:
The patent uses mechanical vibration as a signaling mechanism. The tactile element in the insole vibrates when receiving a vibration command, creating a detectable physical signal that helps the user terminal identify and connect to the correct insole. This mechanical vibration approach simplifies the pairing process by providing intuitive tactile feedback.
2Reliability
If the patent implements vibration feedback for exercise posture correction, then real-time behavior correction is achieved, but energy consumption increases due to continuous sensor operation and vibration actuation
Solution Approach 1:
The patent employs periodic action by only activating the vibration feedback mechanism when exercise posture correction is needed. The pressure sensor continuously monitors foot pressure distribution, and the vibration command is sent only when the center of gravity deviates from the reference area, rather than operating continuously. This reduces energy consumption while maintaining reliable exercise feedback.
3Measurement precision
If the patent uses pressure sensors to detect foot pressure distribution, then accurate center of gravity calculation is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent divides the insole into multiple pressure detection areas (first, second, third, and fourth areas) with pressure sensors positioned at specific locations. Each sensor measures pressure in its designated zone, and the control module processes these segmented measurements to calculate the center of gravity. This segmentation approach achieves accurate measurement while keeping the sensor system manageable in complexity.
