Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional athletic posture analysis devices for golf swings struggle to intuitively display pressure distribution changes on the feet, making it difficult for users to recognize and correct their posture without expert guidance.
Innovation Solution
An athletic posture analysis device equipped with a pressure sensor plate and a controller that maps and tracks foot images and pressure distribution changes, allowing for intuitive visualization of pressure distribution and foot position adjustments during athletic actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional pressure sensor plates are used to measure pressure distribution, then measurement precision is improved, but ease of operation deteriorates because users cannot intuitively understand the data
Solution Approach 1:
The patent creates a visual copy of the foot sole and overlays pressure distribution data onto it. The pressure sensor plate measures precise pressure values at multiple points, then the controller maps these values to corresponding locations on a visual foot image, allowing users to intuitively understand pressure distribution by seeing it overlaid on a recognizable foot shape rather than viewing raw numerical data
Solution Approach 2:
The patent uses color-coded visualization to represent different pressure levels on the foot sole. The controller displays pressure distribution information using varying colors or shades that correspond to different pressure magnitudes, enabling users to quickly grasp pressure patterns through visual perception rather than interpreting numerical values, thus improving ease of operation while maintaining measurement precision
2Measurement precision
If detailed pressure distribution data is provided, then measurement precision is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent merges the visual foot image with the pressure distribution data into a single integrated display. The controller combines the graphical representation of the foot sole with overlaid pressure information, eliminating the need for separate displays of raw data and visual feedback, thus reducing device complexity while maintaining detailed measurement precision
Solution Approach 2:
The visual foot image serves as an intermediary between the pressure sensor plate and the user. Instead of directly processing and displaying complex pressure data from multiple sensor points, the system uses the foot image as a mediator to translate and present the information in an intuitive format, simplifying the overall system architecture while preserving measurement precision
