Tool-Free Display Cable Clamp for Secure Rear-Case Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require separate instruments for assembling or disassembling fastening members like screws to fix cables, reducing consumer convenience and increasing the occurrence of defects and service calls.
Innovation Solution
A display apparatus with a clamp system that includes elastically deformable fixing pins with first and second hooks, allowing cables to be easily fixed to a rear case without additional instruments, providing a secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening member such as a screw is used to fix the cable to the rear case, then the cable can be securely fixed, but a separate instrument is required for assembly and disassembly, reducing consumer convenience
Solution Approach 1:
The clamp is designed to be manually operable by consumers without requiring separate assembly instruments. The clamp body can be directly opened and closed by hand to secure or release the cable, enabling self-service installation and disassembly that improves consumer convenience while maintaining reliable cable fixation
Solution Approach 2:
The invention extracts the fastening function from traditional screw-based fastening members and integrates it into a manually operable clamp structure. This eliminates the need for separate fastening instruments while maintaining the cable securing function, resolving the contradiction between fixation security and operational convenience
2Reliability
If a fastening member such as a screw is used to fix the cable, then the cable can be securely fixed, but the complexity of assembly and disassembly increases due to requiring separate instruments
Solution Approach 1:
The clamp integrates the fastening function and the operating mechanism into a single unified component. The clamp body combines the securing structure with manual opening/closing functionality, eliminating the need for separate fastening members and instruments, thereby reducing assembly process complexity while maintaining fixation reliability
Solution Approach 2:
The clamp serves multiple functions within a single component: it secures the cable, provides a manual operating mechanism, and eliminates the need for separate fastening instruments. This multi-functionality reduces overall device complexity and simplifies the assembly and disassembly processes

AI summary
A display apparatus including display panel, a rear case to cover a rear of the display panel and the rear case including a cable fixing hole to which a cable is fixed, a connector connected to the cable and fastened to the rear case so that the cable is connected to the rear case, a cable holder to surround a part of the cable and fixed to the cable fixing hole so that the cable is fixed to the rear case, and a clamp to fix the cable holder to the cable fixing hole, wherein the clamp includes a first hook to be fixed to the cable fixing hole, and a second hook having a different shape than a shape of the first hook and to be fixed to the cable fixing hole to have a greater fixing force than a fixing force of the first hook.
