Hood Cable Fixing Casing With Hinged Guide for Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hood cable fixing systems for vehicles are prone to separation during assembly, leading to safety hazards and difficulties in inserting cables due to manufacturing defects and burrs, which can result in the hood not opening properly.
Innovation Solution
A hood cable fixing casing with a body part and cover part that includes clip and protrusion portions for secure insertion into the vehicle body, cable insertion guides for proper alignment, and hinged rotation to ensure correct assembly, minimizing insertion force and preventing abnormal assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a mounting bracket made of steel is used to fix the hood cable, then the strength and durability of the fixing structure is improved, but manufacturing defects such as burrs occur during the molding process which make it difficult to insert the hood cable
Solution Approach 1:
The mounting bracket is divided into two separate components: a steel mounting bracket for structural strength and a plastic cable fixing case for cable insertion and guidance. This segmentation allows each component to be optimized for its specific function without the drawbacks of the other material.
Solution Approach 2:
A plastic cable fixing case is introduced as an intermediary component between the steel mounting bracket and the hood cable. This intermediary component provides a smooth insertion surface that guides the cable properly, eliminating the burr-related insertion difficulties while the steel bracket maintains structural strength.
2Productivity
If the hood cable assembly structure is simplified for ease of assembly, then the assembly time is reduced, but the reliability of cable fixation is compromised leading to cable separation during vehicle operation
Solution Approach 1:
The cable insertion guide portions are pre-formed in the cable fixing case, which preliminarily positions and guides the hood cable during insertion. This preliminary action ensures proper cable positioning and secure fixation while maintaining simple assembly procedures.
Solution Approach 2:
The hinged cover portion provides visual and tactile feedback during assembly - when the cover is closed, it confirms that the cable is properly inserted into the guide portions and the mounting bracket is correctly assembled, ensuring reliability without complicating the assembly process.
3Ease of operation
If the cable insertion portions are designed to be easily accessible, then the ease of operation is improved, but the structural integrity and security of cable fixation may be compromised
Solution Approach 1:
The cable insertion guide portions extend in multiple dimensions - vertically from the mounting bracket and horizontally to guide the cable. This multi-dimensional design allows easy cable access and insertion while maintaining secure fixation through the multi-directional guidance structure.
Solution Approach 2:
The cable fixing case has different local qualities: the outer surface provides easy access and guidance for cable insertion, while the inner structure with guide portions and hinged cover provides secure fixation. Each local region is optimized for its specific function.
