Elastic Blocker Wire Frame Liquid-Proof Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid-proof structures for electronic devices are time-consuming to apply, costly, and difficult to disassemble, as they rely on liquid-proof adhesive and are fixed to the device, making maintenance challenging.
Innovation Solution
A liquid-proof structure for wires comprising a wire frame and elastic blockers that limit the position of wires through a casing, preventing liquid ingress by elasticity and liquid resistance, allowing for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid-proof adhesive is used to secure cables and prevent liquid ingress, then liquid-proof protection is achieved, but application time increases and cost increases
Solution Approach 1:
The patent extracts the liquid-proof adhesive from the system and replaces it with a mechanical blocking structure. The cable holder with blocking portions physically blocks liquid ingress without requiring adhesive, thereby eliminating application time while maintaining liquid-proof protection.
Solution Approach 2:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical blocking mechanism. The cable holder's blocking portions mechanically prevent liquid ingress, substituting the chemical system with a purely mechanical one that requires no application time.
2Reliability
If liquid-proof adhesive is used to secure cables and prevent liquid ingress, then liquid-proof protection is achieved, but cost increases
Solution Approach 1:
The patent extracts the expensive liquid-proof adhesive from the system and replaces it with a cost-effective mechanical cable holder structure that achieves the same liquid-proof protection without requiring additional adhesive materials.
Solution Approach 2:
The patent uses a simple, inexpensive cable holder structure made of basic materials (metal or plastic) with blocking portions, replacing the need for expensive liquid-proof adhesive while maintaining adequate liquid-proof protection.
3Reliability
If the liquid-proof structure is fixed to the main-body, then liquid-proof protection is maintained, but disassembly becomes difficult
Solution Approach 1:
The patent segments the liquid-proof structure into a separate, removable cable holder that can be independently assembled and disassembled from the main body. This modular design maintains liquid-proof protection through the blocking portions while enabling easy disassembly for maintenance.
Solution Approach 2:
The patent transforms the static, permanently fixed liquid-proof structure into a dynamic, removable one. The cable holder can be assembled and disassembled as needed, providing flexibility for maintenance while maintaining liquid-proof protection when assembled.

Function Achieved in This Case
The solution provides effective liquid protection for electronic devices while reducing application time and cost, and enabling repeated assembly and disassembly, addressing the limitations of conventional methods.
Implementation Method 1
The blocker is elastic and liquid-proof and is disposed in the accommodating space of the wire frame. The wire is tightly wrapped by the wire slot, so that liquid is prevented from going through the blocker by an elasticity and a liquid-resistance of the blocker

AI summary
A liquid-proof structure for wires includes a wire frame and a blocker. The wire frame has an accommodating space, at least one limiting slot and a second hole. The wire frame is disposed on the first hole and the wire frame provides a connection between an interior of the casing and outside through the second hole. The limiting slot is used for limiting a position of the wire. The blocker has at least one wire slot. The blocker is disposed in the accommodating space of the wire frame, and the wire slot is used for limiting a position of the wire. The wire is limited and fixed by the wire slot of the blocker. The wire is wrapped by the wire slot, so that liquid is prevented from going through the liquid-proof structure by an elasticity and a liquid-resistance of the blocker.
