Problem
Cables in modular robots are prone to wear and movement in small spaces, leading to reduced robot life and safety due to inadequate fixation.
Innovation Solution
A cable guided structure comprising a threading portion, connecting bridge, and mounting portion, with features like threading holes, guiding grooves, and cable sleeves to securely fix and guide cables, preventing abrasion and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ribbon is used for fixing the cable in the mechanical arm without cable guided structure, then the cable can be installed in the robot arm, but the cable is easy to wear and move in small spaces, affecting robot life and safety
Solution Approach 1:
The cable guided structure is divided into multiple functional segments: a mounting portion for attachment, a connecting bridge for structural support, and a threading portion with guiding grooves for cable routing. This segmentation allows each part to perform its specific function efficiently while maintaining overall reliability without excessive complexity.
Solution Approach 2:
The cable guided structure acts as an intermediary component between the mounting portion and the cable. The guiding grooves in the threading portion provide a controlled pathway that mediates cable movement, preventing direct contact and wear between the cable and the robot arm interior surfaces.
2Reliability
If the cable is fixed in small spaces of the robot arm, then the cable can be secured, but the cable is easy to move or wear with the hole wall due to inadequate fixation
Solution Approach 1:
The cable guided structure uses a dedicated threading portion with guiding grooves that provides a controlled pathway for the cable. This structure prevents the cable from contacting and wearing against the robot arm hole walls, effectively protecting the cable in small spaces where fixation is challenging.
3Reliability
If the cable guided structure is used to fix cables in narrow spaces, then cable abrasion and movement are prevented, but the structure complexity increases
Solution Approach 1:
The cable guided structure merges multiple functions into a single integrated component: the mounting portion provides attachment functionality, the connecting bridge provides structural support, and the threading portion with guiding grooves provides cable routing and protection. This merging reduces the need for multiple separate components, maintaining reliability while controlling overall complexity.
