Robot Arm Amplifier Layout for Easy Cover Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots face difficulties in maintenance due to the presence of wires connecting the amplifier part on the cover, making it hard to detach and thus hindering ease of maintenance.
Innovation Solution
The robot design includes a first and second drive part with separate amplifier parts and a first member that separates them from the cover, reducing wire connections and allowing for easier detachment, while also simplifying wiring between drive circuits located on one board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the amplifier part is provided on the cover, then the structure is compact, but the cover cannot be easily detached due to wire connections
Solution Approach 1:
The amplifier part is separated from the cover and mounted on a separate first member inside the arm, dividing the originally integrated structure into distinct segments. This segmentation eliminates the need for wires connecting the amplifier to the cover, allowing the cover to be detached easily while maintaining functional connections through alternative routing.
Solution Approach 2:
The amplifier part is extracted from the cover structure and relocated to a separate mounting position on the first member. By taking out the amplifier from the cover assembly, the patent removes the source of wire complexity while preserving the amplifier's functional role, enabling easy cover removal for maintenance purposes.
2Temperature
If the amplifier part is close to the drive part, then wiring is simplified, but temperature rise and vibration affect the amplifier
Solution Approach 1:
A flexible wire or conduit acts as an intermediary connection between the drive part and the amplifier part, which are positioned at a distance from each other. This intermediary element transmits signals and power while allowing thermal and vibrational isolation, enabling the amplifier to be positioned away from heat-generating components while maintaining electrical connectivity.
3Ease of repair
If multiple amplifier parts are provided, then multiple drive parts can be controlled, but maintenance accessibility is reduced
Solution Approach 1:
Multiple amplifier parts are segmented and individually mounted on separate first members within the arm structure, rather than being integrated into a single unit. This segmentation allows each amplifier to be accessed and maintained independently, improving maintenance accessibility while supporting multiple drive parts.
Solution Approach 2:
Each amplifier part is extracted from a common housing and individually positioned on separate mounting structures, enabling independent access to each amplifier for maintenance purposes. This extraction approach maintains the functionality of controlling multiple drive parts while significantly improving maintenance accessibility.
