Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walking assistance devices fail to account for ground inclination, leading to inefficiencies and safety risks during exercises such as outdoor walking or running, as they do not adjust exercise speed or intensity based on the terrain's slope, potentially causing exhaustion or accidents.
Innovation Solution
A wearable device and electronic system that determines ground inclination and adjusts target exercise speed and intensity accordingly, using sensors to measure motion and terrain data, and a processor to control motor torque for optimal exercise performance and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable device maintains a fixed target exercise speed regardless of ground inclination, then the device structure remains simple, but the exercise efficiency and safety deteriorate due to inability to adapt to terrain changes
Solution Approach 1:
The wearable device automatically detects ground inclination through sensors and adjusts exercise parameters without user intervention. The control unit autonomously processes sensor data and modifies motor output, allowing the device to serve itself in adapting to terrain changes.
Solution Approach 2:
The system continuously monitors ground inclination via sensors and uses this feedback to dynamically adjust exercise parameters. The control unit receives real-time inclination data and modifies motor torque accordingly, creating a closed-loop control system that adapts to changing terrain conditions.
2Productivity
If the wearable device increases exercise intensity to compensate for downward slopes, then exercise amount is maintained, but safety risks increase due to potential overexertion or loss of control
Solution Approach 1:
The wearable device dynamically adjusts exercise parameters based on real-time ground inclination detection. The system transitions from static fixed-speed operation to dynamic speed modulation, allowing optimal exercise intensity maintenance while adapting to terrain variations through continuous parameter adjustment.
3Reliability
If the wearable device reduces exercise speed on upward slopes to maintain safety, then safety is improved, but exercise efficiency deteriorates due to insufficient exercise amount
Solution Approach 1:
The system changes operational parameters (speed, torque, power) based on detected ground inclination. By adjusting motor output parameters in response to terrain slope, the device maintains safe operation while compensating for reduced exercise effectiveness through parameter optimization.
