Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots face issues with distortion or separation of their outer body due to external impacts or drops, which can lead to malfunction and damage.
Innovation Solution
A robot design featuring a tilting base and tilting mechanism with a hook unit and supporting rib system that elastically attaches and detaches the first and second bodies of the outer body, ensuring they remain firmly connected and maintain their shape under external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the outer body is composed of multiple members, then the robot can be easily assembled and disassembled, but the members may be pushed or twisted and separated during drops or impacts
Solution Approach 1:
The outer body is divided into multiple members (first body and second body) that can be separately manufactured and assembled, improving ease of manufacture while maintaining structural integrity through the coupling mechanism
Solution Approach 2:
The coupling mechanism incorporates elastic elements that allow dynamic adjustment and absorption of impact forces, enabling the structure to adapt to external forces while maintaining connection between members
Solution Approach 3:
Multiple coupling mechanisms (hook unit, hanger units, supporting rib) are combined to work together, providing both easy assembly capability and robust structural integrity against separation forces
2Reliability
If rigid fastening is used to prevent separation, then structural integrity is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The coupling mechanism uses elastic elements that provide rigid fastening under normal conditions but allow easy release when force is applied, achieving both structural integrity and ease of operation
Solution Approach 2:
The elastic element acts as an intermediary between the fastening and release mechanisms, storing energy during assembly and releasing it during disassembly, thereby enabling both strong connection and easy separation
3Strength
If the outer body members are firmly connected, then resistance to separation during impact is improved, but the complexity of the coupling mechanism increases
Solution Approach 1:
The coupling mechanism is segmented into multiple simple components (hook, hanger units, supporting rib) that work together to provide strong resistance to separation without requiring a complex single mechanism
Solution Approach 2:
The coupling mechanism components serve multiple functions: the hook provides primary connection, hanger units provide secondary support, and the supporting rib provides structural reinforcement, thereby achieving high strength with relatively simple components
