Robot Wire Management via Detachable Distribution Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots with rotating drums face challenges in managing wire loads during rotation, leading to potential damage and interference issues with connectors and wire management.
Innovation Solution
A robot design featuring a base with an opening portion for wire entry, a hollow portion along the axis connecting the base to the rotating drum, and a detachable distribution board member with a larger relay portion for connector mounting, allowing for reduced height without compromising motion range or wire management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wire members are led directly into the rotating drum through the base, then wire load management is simplified, but the opening portion area is limited and connector mounting space is insufficient
Solution Approach 1:
The distribution board member is divided into distinct functional regions: an attachment portion for mounting to the base and a relay portion for connector installation. This segmentation allows the relay portion to extend beyond the opening portion area, providing sufficient space for connector mounting while keeping the wire entry path through the opening portion simple and direct.
Solution Approach 2:
The distribution board member acts as an intermediary component between the base and the rotating drum. It provides a relay portion that extends beyond the opening portion, creating additional space for connector mounting without requiring the opening portion itself to be larger. This intermediary structure resolves the conflict between limited opening area and connector space requirements.
2Length of moving object
If the robot height is reduced, then the overall size is compact, but there is insufficient space for connector mounting and wire management
Solution Approach 1:
Instead of increasing robot height to provide connector mounting space, the distribution board member extends the relay portion in a horizontal direction beyond the opening portion. This dimensional shift allows connector mounting space to be created without increasing the vertical height of the robot, thus maintaining compact size while providing adequate connector installation area.
3Area of stationary object
If the opening portion area is increased, then connector mounting space is improved, but wire load management becomes more difficult during rotation
Solution Approach 1:
The connector mounting function is extracted from the opening portion area and relocated to the relay portion of the distribution board member. This extraction allows the opening portion to remain small and simple, maintaining good wire load management characteristics, while the relay portion provides adequate space for connector mounting. The wire entry path remains direct through the opening portion, preventing excessive wire loading during rotation.
