Solution Overview
Problem
Existing splice sleeve assembly devices face challenges in providing a sealed and secure mounting solution for cables, especially at low temperatures and in varying environmental conditions, with existing solutions either lacking in sealing effectiveness or requiring additional fastening elements.
Innovation Solution
The assembly device incorporates two deformation elements with different functions and material properties, where one ensures secure hold and the other provides sealing, even at low temperatures, and these elements are fixed in a relative position using a fastening element, allowing for secure sealing and holding without the need for additional fastening wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single deformation element is used to secure the cable, then the structure is simple, but the sealing effectiveness deteriorates especially at low temperatures
Solution Approach 1:
The single deformation element is divided into two separate deformation elements with different functions: a first deformation element for securing the cable and a second deformation element for sealing. This segmentation allows each element to be optimized for its specific function, resolving the contradiction between structural simplicity and sealing effectiveness.
Solution Approach 2:
Different regions of the mounting device are assigned different material properties: the first deformation element uses material optimized for mechanical securing, while the second deformation element uses material optimized for sealing performance at low temperatures. This local quality differentiation resolves the contradiction by providing specialized functionality in each region.
2Strength
If separate fastening elements are used to secure the deformation elements, then the holding strength is improved, but the device complexity increases
Solution Approach 1:
The fastening function is merged into the mounting device housing itself, which serves both as the structural container and as the fastening element. The housing includes engagement features that directly secure the deformation elements without requiring separate fastening components, thus maintaining holding strength while reducing device complexity.
Solution Approach 2:
The mounting device housing performs multiple functions: it contains the deformation elements, provides structural support, and acts as the fastening mechanism through integrated engagement features. This multi-functionality eliminates the need for separate fastening elements while maintaining holding strength.
3Ease of operation
If deformation elements are not pre-fixed in relative position, then the ease of installation is improved, but the sealing reliability deteriorates
Solution Approach 1:
The deformation elements are pre-fixed in the mounting device housing at their correct relative positions before installation. This preliminary action ensures that when the device is installed, the elements are already properly positioned for effective sealing, eliminating the need for complex alignment operations while maintaining sealing reliability.
