Hood Lock Cable Routing Through Support Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing the cable of the hood locking set in vehicles are either too bulky, incompatible with reduced hood height designs, or constrained by the transverse size of the vehicle's front, which limits cable curvature and functionality.
Innovation Solution
The proposed solution involves a load-bearing framework element with a wall plurality and an orifice that allows the cable to pass transversely, reducing the need for vertical fixation and enabling more flexible cable routing with increased curvature angles.

Engineering Contradiction Analysis
1Volume of moving object
If the cable is attached above or below the supporting frame element using conventional methods, then the cable is securely fixed, but additional vertical bulk is generated that increases the hood height
Solution Approach 1:
The cable routing is changed from a vertical attachment (above or below the frame element) to a transverse routing through the frame element. The cable passes through an orifice in the supporting frame element and is secured by a retaining element on the lateral face, transforming the fixation from vertical to horizontal dimension, thereby reducing vertical bulk while maintaining secure fixation
Solution Approach 2:
A retaining element is introduced as an intermediary component to secure the cable. This retaining element is fixed to the lateral face of the supporting frame element and engages with the cable, providing secure fixation without requiring vertical space above or below the frame element
2Area of stationary object
If the cable is routed with tight bends to fit within transverse dimensions, then space is saved, but the cable's proper operation is compromised
Solution Approach 1:
The retaining element acts as an intermediary that provides a secure attachment point for the cable on the lateral face of the frame element. This allows the cable to be positioned optimally without requiring tight bends, ensuring both proper cable operation and efficient use of transverse space
Solution Approach 2:
The cable routing parameters are optimized by changing from tight bends to a more relaxed transverse routing through the orifice. The cable is allowed to extend with adequate curvature radius while still fitting within the transverse dimensions, maintaining both functionality and space efficiency
