Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors lack effective mechanisms to securely fix cables and prevent external contaminants from entering, leading to potential damage and connection failures.
Innovation Solution
A cable fixing apparatus comprising a first sleeve with a thread portion, a second sleeve with a through hole and a clamp mechanism, which securely engages and clamps the cable, preventing movement and external impurities, while allowing for easy assembly and disassembly without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cable connector is used without an effective cable fixing mechanism, then the structure is simple, but the cable cannot be securely fixed and is prone to movement and damage
Solution Approach 1:
The patent employs a nested structure where the first sleeve and second sleeve are concentrically arranged, with the clamp mechanism nested within the second sleeve. This nesting approach achieves secure cable fixation through multiple concentric protective layers without significantly increasing overall structural complexity, as each component fits within the previous one.
Solution Approach 2:
The cable fixing apparatus is divided into distinct functional segments: the first sleeve for initial cable reception, the second sleeve for additional protection and threading, and the clamp mechanism for secure fixation. This segmentation allows each component to perform its specific function efficiently while maintaining overall structural simplicity.
2Reliability
If a cable connector lacks a sealing mechanism, then the structure is simpler, but external impurities such as moisture and dust can enter and cause connection failures
Solution Approach 1:
The sealing mechanism is integrated within the nested sleeve structure, where seal members are positioned between the first sleeve and second sleeve, and within the clamp mechanism. This nested sealing approach provides multiple barriers against impurities without requiring separate external sealing components.
Solution Approach 2:
The sealing function is merged with the structural components of the connector. The seal members are integrated into the clamp mechanism and sleeve assemblies, combining the functions of mechanical fixation and environmental sealing into unified components rather than separate systems.
3Ease of operation
If a tool-free assembly mechanism is used, then ease of operation is improved, but the securing strength may be compromised
Solution Approach 1:
The clamp mechanism incorporates movable clamp arms that can dynamically adjust their position and clamping force. The spring element provides continuous dynamic pressure to maintain secure cable fixation. This dynamic design allows tool-free assembly while ensuring adequate securing strength through elastic deformation and progressive clamping.
Solution Approach 2:
The spring-loaded clamp mechanism is self-actuating, using the insertion motion itself to compress the spring and engage the clamp arms. The system serves itself by converting the assembly motion into the securing action, eliminating the need for external tools while maintaining strong cable fixation through elastic recovery force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively secures cables, prevents damage and connection failures, and enhances sealability by using a clamp mechanism that gradually clamps the cable and includes a seal member to prevent moisture and dust from entering the connector.
Implementation Method 1
a first thread portion at a first end of the first sleeve... The second sleeve is threaded onto the first thread portion at a second end of the second sleeve
Implementation Method 2
The clamp mechanism clamps the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving

AI summary
A cable fixing apparatus adapted to be fixed to an end of a cable includes a first sleeve having a first thread portion at a first end of the first sleeve, a second sleeve having a bottom portion with a through hole at first end of the second sleeve, and a clamp mechanism disposed in the second sleeve between the first thread portion of the first sleeve and the bottom portion of the second sleeve. The cable is inserted into the second sleeve and the first sleeve through the through hole in an insertion direction. The second sleeve is threaded onto the first thread portion at a second end of the second sleeve. The clamp mechanism clamps the cable in response to an engagement of the second end of the second sleeve to the first thread portion to prevent the cable from moving in the first sleeve and the second sleeve.
