Load Detecting Device with Flare Portion for Walk Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load detecting devices for walk training devices have limited detecting areas, which can lead to reduced accuracy in measuring the load of walk trainees, especially those who are easily unbalanced, as the sensors are only disposed within the sole shape and not extended to the flare portion.
Innovation Solution
A load detecting device with a sole shape portion and a flare portion that projects outside, equipped with first and second load sensors to detect loads within the sole and flare areas, respectively, along with center calculation means, storage means, and communication means to enhance accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If load sensors are disposed only within the sole shape portion, then the device structure is simple, but the detecting area is limited and detection accuracy is reduced
Solution Approach 1:
The load detecting device is segmented into two functional areas: the sole shape portion and the flare portion. Each area has dedicated load sensors (first load sensors for sole shape portion, second load sensors for flare portion), allowing independent detection in each region. This segmentation enables extended detection coverage without creating a single complex sensor array, resolving the contradiction between detection accuracy and device complexity.
2Measurement precision
If the detecting area is extended to the flare portion, then load detection accuracy is improved, but the number of sensors and device complexity increases
Solution Approach 1:
The load detecting device uses a unified detection system that serves multiple functions: detecting loads in the sole shape portion and loads in the flare portion simultaneously. The center calculation means integrates data from both first and second load sensors to calculate the center of sole load, providing comprehensive gait analysis with a single device rather than requiring separate detection systems for each area, thus reducing the overall quantity of sensors needed.
3Measurement precision
If load sensors are disposed only within the sole shape portion, then device complexity is low, but the detecting area does not cover the flare portion leading to reduced accuracy for unbalanced walk trainees
Solution Approach 1:
The device structure is designed in advance with pre-defined detection zones (sole shape portion and flare portion) and pre-positioned sensors in each zone. The center calculation means is pre-programmed to integrate data from both regions. This preliminary design approach allows for standardized manufacturing processes and simplifies assembly, maintaining ease of manufacture while achieving extended detection coverage for improved accuracy.

AI summary
A load detecting device includes a sole shape portion that is formed along a shape of a sole of a walk trainee, and on which the sole gets, a flare portion that is formed so as to project outside the sole shape portion, a first load sensor that is provided at the sole shape portion and detects the load of the sole shape portion, and a second load sensor that is provided at the flare portion and detects the load of the flare portion.
