Robot Umbilical Attachment Device Independent Cable Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing umbilical member attachment systems for robots are cumbersome and complicated, particularly when detaching or replacing multiple umbilical members, as they require multiple clamps and involve complex detachment procedures, leading to increased work effort and space requirements.
Innovation Solution
A umbilical member attachment device with a base part detachably attached to rotating robot members, featuring separate fastening parts for basic and option cables, allowing for independent detachment and attachment of each type of cable, reducing the need for simultaneous detachment of all cables and simplifying the replacement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple umbilical members are fastened by separate clamps, then each umbilical member can be fastened independently, but the number of clamps increases and detachment work becomes troublesome
Solution Approach 1:
Multiple separate clamps are merged into a single integrated clamp structure that can fasten multiple umbilical members simultaneously. The clamp includes multiple clamping portions that can independently secure different umbilical members while being operated as one unit, reducing the total number of clamps needed.
Solution Approach 2:
The clamp is designed with multi-functionality to serve multiple purposes: it can fasten different types of umbilical members (basic cables and option cables), can be attached to various robot members, and provides both secure fastening and easy release capabilities in a single device.
2Device complexity
If multiple umbilical members are fastened by the same clamps, then the number of clamps is reduced, but replacement of some umbilical members requires detachment of all umbilical members
Solution Approach 1:
The clamp structure is segmented into multiple independent clamping portions, each capable of fastening a specific umbilical member. These portions can be independently released, allowing selective detachment of individual umbilical members without requiring release of all clamping portions, thus facilitating easier replacement.
Solution Approach 2:
The clamp incorporates dynamic release mechanisms that allow selective engagement and disengagement of different clamping portions. This enables the operator to release only the specific portion needed for umbilical member replacement while maintaining fastening of other portions, making the replacement process more efficient.
3Ease of operation
If all umbilical members are detached for replacement, then complete access is achieved, but the work becomes complicated and time-consuming
Solution Approach 1:
The attachment device is divided into separable components including the base part and the clamp, which can be independently attached and detached. This segmentation allows partial disassembly for targeted umbilical member replacement, providing sufficient access without requiring complete detachment of all components, thereby reducing replacement time.
