Athletic Posture Analysis Device Foot Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional athletic posture analysis devices, such as those for golf swing analysis, struggle to intuitively and visibly display weight shift information, making it difficult for users to recognize and correct their posture without expert assistance.
Innovation Solution
An athletic posture analysis device equipped with a pressure sensor plate and a controller that maps a foot image to match the size and position of the user's feet, overlaying pressure distribution information for intuitive understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional athletic posture analysis devices provide weight shift analysis information, then measurement precision is improved, but ease of operation deteriorates because the information is difficult for users to recognize and understand
Solution Approach 1:
The patent creates a visual copy of the foot (foot image) and overlays pressure distribution information onto it. This allows users to intuitively understand weight shift by seeing the pressure distribution pattern superimposed on the foot shape, transforming complex numerical data into an easily recognizable visual format that directly corresponds to the user's own foot anatomy
Solution Approach 2:
The patent uses color or intensity variations in the displayed pressure distribution map to indicate different pressure levels. By using visual intensity changes (such as darker regions for higher pressure, lighter regions for lower pressure), the system makes the abstract pressure data immediately recognizable and interpretable by users without requiring technical expertise
2Measurement precision
If conventional devices provide detailed pressure distribution data, then measurement precision is improved, but device complexity increases making it less suitable for home use
Solution Approach 1:
The patent extracts only the essential visual information needed for user understanding - the pressure distribution pattern overlaid on the foot image - while filtering out unnecessary complex data processing and presentation mechanisms. This selective extraction allows the system to maintain measurement precision while presenting information in a simple, intuitive format suitable for home use without requiring complex interfaces or expert interpretation
3Ease of operation
If the system displays mapped foot image with pressure distribution, then ease of operation is improved for user understanding, but device complexity increases due to image processing requirements
Solution Approach 1:
The patent uses a pre-generated foot image template as an intermediary element. Instead of directly displaying complex pressure data or requiring real-time complex image processing, the system overlays pressure distribution information onto a standardized foot image template. This intermediary template simplifies the display mechanism while maintaining intuitive understanding, as the foot image provides immediate visual context for interpreting pressure distribution patterns
