Elastic Anti-Collision Structure for Damage-Resistant Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-collision devices in robots, such as lawn mowers, are susceptible to damage during collisions and require frequent replacement, leading to increased maintenance costs and downtime.
Innovation Solution
An anti-collision device with a first elastic member that deforms upon impact, deflecting the working structure relative to the connecting member, thereby reducing the impact force and preventing damage, and a detachable design for easy maintenance and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid anti-collision device is used to detect obstacles, then collision detection capability is improved, but the device is susceptible to damage during collisions
Solution Approach 1:
The anti-collision device incorporates an elastic member that allows the working structure to move dynamically during collision. The elastic member enables the device to deform and absorb impact energy, transforming the rigid structure into a dynamic one that can withstand collision forces while maintaining detection capability.
Solution Approach 2:
The elastic member is pre-installed between the working structure and the connecting member to provide cushioning before collision occurs. This beforehand cushioning mechanism absorbs impact energy during collision, protecting the anti-collision device from damage while maintaining its detection function.
2Ease of repair
If the anti-collision device is made detachable for easy maintenance, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The anti-collision device is segmented into detachable components: the working structure, the elastic member, and the connecting member. This segmentation allows the device to be disassembled and reassembled easily for maintenance while keeping the overall connection structure relatively simple through standardized interfaces.
