Cable-Clamping Device Segmentation for Mold Simplicity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable-clamping devices for electrical cables are complex and costly to manufacture due to the need for sliding parts in moulds, especially when producing thermoplastic synthetic plastic resin components with undercuts.
Innovation Solution
A cable-clamping device designed for simple and cost-effective manufacturing using a single mould operation without sliding parts, featuring a base with a through seat and a clamping element connected via snap engaging retaining means, allowing for integral moulding of the base and clamping element with a deformable tongue, and utilizing a transversal slot and recesses to create an insertion seat for screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If sliding parts are used in the mould to manufacture cable-clamping devices with undercuts, then the manufacturing capability and product shape complexity are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The cable-clamping device is divided into two separate components: a base and a clamping element. The clamping element can be inserted into the base through a through-seat, allowing each component to be manufactured separately using simple moulds without sliding parts, while still achieving the final complex assembled shape.
Solution Approach 2:
The clamping element is nested within the base structure, with the clamping element being insertable into the base through the through-seat. This nesting arrangement allows complex functionality to be achieved through component insertion rather than complex moulding.
2Shape
If sliding parts are used in the mould to manufacture cable-clamping devices, then the manufacturing capability is improved, but the productivity and manufacturing efficiency decrease
Solution Approach 1:
By segmenting the device into base and clamping element components that can be manufactured separately using simple moulds, the manufacturing process becomes faster and more efficient, eliminating the need for complex sliding mechanisms in the mould while still achieving the required product shape.
3Strength
If the clamping element is firmly fixed to the base, then the structural integrity is improved, but the adaptability and cable adjustment capability decrease
Solution Approach 1:
The connection between the clamping element and base is made adjustable through threaded fasteners, allowing the structural integrity to be firmly secured when needed, while also enabling easy adjustment and removal of cables, providing both strength and adaptability.
