Vehicle Assembly Skid With Guide Device For Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the assembly of vehicles, there is a risk of snagging and damaging gearbox control cables and electrical harnesses when they pass through an opening in the vehicle body, leading to inefficiencies and ergonomic challenges for operators as they must handle closing parts manually while connecting cables.
Innovation Solution
A preparation sled equipped with a protective casing that guides elongated flexible members, allowing the moving parts to be housed and transported, keeping operators' hands free and improving ergonomics by enabling the automatic placement of closing parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide device passes through the opening in the bodywork during styling, then the cables are protected from snagging and damage, but the operator must manually position the moving part for closing the opening while having only one hand free
Solution Approach 1:
The moving part for closing the opening is housed inside the guide device. The guide device acts as a container that transports the moving part through the styling opening, eliminating the need for separate manual positioning operations and freeing the operator's hands.
Solution Approach 2:
The moving part is pre-positioned inside the guide device before the styling operation. This preliminary positioning ensures that the moving part is already in place when needed, eliminating the need for subsequent manual intervention and improving operational efficiency.
2Productivity
If the operator manually positions the moving part for closing the opening, then the assembly can be completed, but time is lost and ergonomics are degraded
Solution Approach 1:
The moving part is nested within the guide device, which transports it through the styling opening. This integration eliminates separate handling operations, reduces assembly time, and maintains good ergonomics by keeping the operator's hands free.
Solution Approach 2:
The guide device automatically transports and positions the moving part through the styling opening without requiring manual intervention. The system serves itself by integrating the moving part within the guide device structure, eliminating time-consuming manual operations.
3Reliability
If the guide device is used to protect cables during styling, then cable damage is prevented, but the moving part for closing the opening cannot be pre-positioned on the support
Solution Approach 1:
The guide device and the moving part for closing the opening are merged into a single integrated structure. The moving part is housed within the guide device, combining two previously separate elements into one unified component that performs both cable protection and provides the closing part.
Solution Approach 2:
The moving part is nested inside the guide device, creating a hierarchical structure where one component contains another. This nesting resolves the conflict between cable protection and moving part positioning by making the moving part an integral part of the guide device structure.
