Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots designed for daily life applications suffer from limited service utilization due to their specific service designs, and during charging, excessive external force can damage the charging terminal or the robot, leading to reliability issues.
Innovation Solution
A robot system with a charging terminal mounter and a processor that uses elastic springs to gently dock with a charging station, minimizing force application and incorporating a switch to stop the driving wheels when the terminal is fully engaged, ensuring safe and reliable charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot drives to dock with the charging station, then the charging terminal can be connected for power supply, but excessive external force may be applied to the charging terminal until stopping is completed, causing damage
Solution Approach 1:
A cushioning member is provided between the charging terminal and the charging terminal mounter to absorb excessive external force during docking. The cushioning member compresses when the robot continues moving after the charging terminal makes contact with the supply terminal, preventing damage to the charging terminal and other components.
2Manufacturing precision
If the robot continues moving after charging terminal contact until stopping is completed, then the robot can be precisely positioned, but excessive force damages the charging terminal
Solution Approach 1:
The cushioning member is pre-positioned to absorb impact forces that occur when the robot continues moving after the charging terminal makes contact. This allows the robot to maintain precise docking positioning while the cushioning member protects against damage from the continued motion.
3Strength
If a rigid connection is used between charging terminal and mounter, then structural strength is improved, but damage occurs during docking due to inability to absorb force
Solution Approach 1:
Instead of using a rigid connection, a cushioning member is introduced between the charging terminal and the charging terminal mounter. This cushioning member can compress to absorb docking impact forces, protecting the charging terminal and other components while maintaining structural integrity.
Solution Approach 2:
The connection between the charging terminal and mounter is made dynamic through the cushioning member, which can change its stiffness characteristic during docking. The cushioning member transitions from a uncompressed state to a compressed state, allowing the system to adapt to the impact forces during docking.
