Exercise Mat with Pressure Sensors for Body Area Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices are limited in recording physical exercises beyond walking or running, as they cannot accurately capture and record variations in pressure values from different body areas during various exercises.
Innovation Solution
A mat equipped with pressure sensors that determines critical force areas and sends exercise information to a terminal, including the exercise status, by measuring pressure variations at these areas, allowing for real-time recording of diverse physical activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electronic devices are used to record physical exercise, then walking or running can be recorded, but other physical exercises cannot be accurately captured and recorded
Solution Approach 1:
The mat is divided into multiple sensing zones with pressure sensors distributed across different areas. Each zone independently detects pressure at specific body contact points (head, feet, hips, arms), enabling the system to distinguish between different exercise types by analyzing pressure patterns at segmented locations rather than treating the surface as a single unit.
Solution Approach 2:
The mat serves as an intermediary device between the user's body and the recording system. Pressure sensors embedded in the mat detect force applied by different body parts during exercise, converting mechanical pressure into electrical signals that are transmitted to the terminal for analysis and recording of exercise status.
2Measurement precision
If pressure sensors are deployed across the entire mat surface, then all body areas can be monitored, but device complexity and cost increase
Solution Approach 1:
Pressure sensors are strategically positioned only at critical force areas where body contact occurs during exercise (head, feet, hips, arms), rather than uniformly distributing sensors across the entire mat surface. This localized sensor deployment captures essential exercise information while minimizing the total number of sensors required, reducing device complexity and cost.
Solution Approach 2:
The mat with strategically placed pressure sensors serves multiple functions: it detects various exercise types (sit-ups, push-ups, leg raises), monitors different body parts, and provides comprehensive exercise status information. The same sensor configuration handles diverse exercise scenarios without requiring additional specialized sensors for each exercise type.
