Wire Cabling Device with Segmented Case and Regulation Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire cabling devices for vehicles require two distinct metal molds due to non-constant sectional shapes along the sliding direction, leading to increased production costs and limited manufacturing productivity, as they cannot be shared or produced through high-productivity methods like roll forming or extrusion molding.
Innovation Solution
A wire cabling device with a case having a constant sectional shape along the sliding direction, featuring a regulation member formed independently and attachable at multiple positions, allowing for rotation and common use across different vehicle configurations, and manufactured using roll forming or extrusion molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the case is formed with a non-constant sectional shape along the sliding direction to regulate the cabling route, then the cabling route can be controlled, but two distinct metal molds are required increasing production cost and reducing productivity
Solution Approach 1:
The case is divided into two functional parts: a cylindrical main body with constant sectional shape for cost-effective manufacturing, and a separate regulation member with non-constant shape for cabling route control. This segmentation allows each part to be optimized independently - the main body for manufacturing efficiency and the regulation member for functional requirements.
Solution Approach 2:
The regulation function is extracted from the case structure and implemented as a separate regulation member that can be attached to the cylindrical case. This extraction enables the case to maintain a simple constant sectional shape while the regulation member provides the necessary cabling route control.
2Productivity
If the case is made with constant sectional shape for high-productivity manufacturing, then productivity increases, but the ability to regulate cabling route is lost
Solution Approach 1:
The device is segmented into a simple cylindrical case for high-productivity manufacturing and a separate regulation member for cabling route control. This segmentation enables the case to be produced using efficient roll forming or extrusion molding while the regulation member handles the complex routing function.
Solution Approach 2:
The regulation member acts as an intermediary element that provides the complex cabling route control function without requiring the case itself to have a complex shape. This intermediary approach maintains manufacturing simplicity while achieving the desired routing regulation.
3Adaptability or versatility
If the case is designed with specific non-constant shape for dedicated applications, then the cabling function is optimized, but the case cannot be commonly used across different vehicle configurations
Solution Approach 1:
The cylindrical case with constant sectional shape serves as a universal component that can be applied to different vehicle configurations. The regulation member is attached to this universal case to provide the specific cabling route control needed for each application, enabling one case design to serve multiple purposes.
Solution Approach 2:
The case maintains uniform constant sectional shape throughout its length, providing consistent manufacturing quality. The local cabling regulation needs are addressed by the separately attached regulation member, allowing the case itself to be manufactured with high precision using standard processes.
