Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable fixing structures for electronic devices are complex and costly due to the need for precise bonding with the shell, which increases manufacturing costs and complexity.
Innovation Solution
A cable connecting and fixing structure that includes a protective structure with a clamping part and a bonding material, where the cable passes through a fixed connection hole in the shell, and the bonding material cures to form a hard tensile structure, ensuring secure attachment without additional structural modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional dispensing structure or multi-layer clamping structure is designed to fix cable connecting structure to shell, then tensile strength and resistance to reverse pulling forces is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the cable fixing structure with the shell by integrating a bonding layer between them, merging two previously separate components (cable fixing structure and shell) into a unified assembly. This eliminates the need for complex dispensing structures or multi-layer clamping structures while maintaining tensile strength through the bonded connection.
Solution Approach 2:
The patent extracts the cable fixing function from complex mechanical structures (dispensing structures, multi-layer clamping structures) and implements it through a simplified bonding mechanism. The bonding layer serves as the primary fixing element, removing the need for elaborate mechanical fixing components.
2Reliability
If conventional methods bond outer shell and cable connecting structure simultaneously, then cable fixation is achieved, but manufacturing cost increases due to precise bonding requirements
Solution Approach 1:
The patent segments the bonding process into distinct stages: first bonding the cable connecting structure to the bonding layer, then bonding the assembly to the shell. This segmentation allows each bonding operation to be performed independently with standard procedures, eliminating the need for complex simultaneous multi-component bonding while maintaining fixation reliability.
Solution Approach 2:
The patent performs preliminary bonding of the cable connecting structure to the bonding layer before final assembly with the shell. This preliminary action simplifies the overall manufacturing process by pre-positioning and securing components, reducing the complexity and cost of the final bonding operation.
3Stability of the object's composition
If clamping part is designed to clamp outer shell, then cable connection stability is improved, but additional structural modifications and manufacturing complexity increase
Solution Approach 1:
The patent replaces the mechanical clamping system with a chemical bonding system. Instead of using a clamping part that mechanically grips the shell, the invention uses a bonding layer that chemically adheres both the cable connecting structure and the shell, providing stable connection without mechanical complexity.

AI summary
The present invention provides a cable connecting and fixing structure and a method for arranging the cable connecting and fixing structure. The method for arranging the cable connecting and fixing structure includes the following steps: providing a cable body and a protective structure, the protective structure being provided with a clamping part; sleeving the cable body with the protective structure; enabling the cable body to pass through a fixed connection hole until an outer shell is clamped on the clamping part of the protective structure; and curing a bonding material to bond and strengthen the protective structure and the cable body, and the hardness of the cured bonding material being greater than the hardness of the protective structure.
