Treadmill Load Distribution Sensor for Walking State Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking training systems face challenges in accurately determining the walking state of users due to the low response performance of load distribution sensors, leading to unintentional detection of load distribution before movement, which affects the effectiveness of training.
Innovation Solution
A walking training system equipped with a load distribution sensor on the treadmill belt that does not move with the belt, along with an extraction unit and a determination unit to isolate and accurately detect the load distribution corresponding to the user's sole size and position, improving the accuracy of walking state determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a load distribution sensor is provided on the treadmill belt to detect load distribution, then the ability to detect walking state is improved, but the response performance becomes insufficient when unloaded, causing unintentional detection of load distribution before movement
Solution Approach 1:
The patent extracts and removes the load distribution sensor from the treadmill belt, placing it on the floor instead. This separation allows the sensor to remain stationary and independent from the belt's movement, eliminating the response performance issues that occurred when the sensor was mounted on the moving belt. The sensor can now reliably detect load distribution without being affected by belt motion.
Solution Approach 2:
The patent introduces an intermediary mechanism (image processing system) that captures the position of the user's foot and translates it into load distribution information. This intermediary approach allows the system to determine walking state without relying on the sensor's direct response to belt movement, thereby resolving the reliability issue while maintaining measurement precision.
2Area of stationary object
If the load distribution sensor is mounted on the belt to move with the belt, then the detection coverage is improved, but the sensor cannot accurately distinguish between load distribution before and after movement due to low response performance
Solution Approach 1:
The patent extracts the sensor mounting from the belt and relocates it to the floor. This extraction allows the sensor to maintain a fixed detection area while the user's foot moves across it, enabling accurate distinction between pre-movement and post-movement load distribution. The sensor's detection coverage remains sufficient while achieving precise temporal resolution.
Solution Approach 2:
The patent employs preliminary action by capturing the user's foot position using an image processing system before the foot actually contacts the sensor. This allows the system to pre-identify the intended load distribution area, enabling accurate differentiation between anticipated and actual load distribution, thereby improving measurement precision while maintaining detection coverage.
