Integrated Wall Module Base and Terminal Strip Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for installing electrical equipment modules in juxtaposed positions on walls are lengthy, difficult to center, result in additional thickness, are not suitable for hollow partitions, and incur high manufacturing costs due to numerous components, with overheating and electrical losses at connection zones.
Innovation Solution
A simplified assembly where part of the connection strip forms a one-piece assembly with a module, allowing direct attachment to the wall without creating an oblong opening, reducing component count, and using welding or crimping to connect conductors, which minimizes overheating and electrical losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two separate modules with a connection strip are used to install electrical equipment in juxtaposed position, then the installation can be performed on hollow partitions and centering is simplified, but the assembly produces large extra thickness and requires multiple separate components increasing complexity
Solution Approach 1:
The patent merges the connection strip and module base into a single integrated base structure. The connection strip is formed as an integral part of the module base, eliminating the need for separate connection strips and reducing the number of components while maintaining the ability to install multiple modules in juxtaposed position on hollow partitions
2Ease of manufacture
If modules are fixed directly to the wall without engagement in the wall, then installation is simplified, but large extra thickness is produced which is unattractive
Solution Approach 1:
The patent extends the base in the direction perpendicular to the wall (the third dimension) to create a reduced protrusion configuration. The base is designed with an extended portion that allows the module to engage partially with the wall structure, reducing the extra thickness while maintaining direct fixation simplicity
3Reliability
If pins of connection strips are oriented towards the front for connection, then electrical connection is achieved, but the module thickness must be greater than pin length creating additional protrusion
Solution Approach 1:
The patent inverts the traditional orientation by having the connection elements extend from the rear of the base rather than the front. This allows electrical connection to be made from the rear side, eliminating the need for the module thickness to accommodate front-oriented pins and reducing overall protrusion
4Strength
If conventional screwing methods are used to center modules, then secure fixation is achieved, but perfect centering along horizontal axis is difficult and installation becomes tedious
Solution Approach 1:
The patent incorporates preliminary centering features directly into the base structure, such as pre-positioned mounting holes or alignment guides that automatically center the module during installation. This preliminary action eliminates the need for complex screwing operations to achieve perfect centering while maintaining secure fixation
5Adaptability or versatility
If multiple separate elements are used to assemble modules and connection strips, then flexibility in assembly is achieved, but manufacturing cost increases due to large number of components
Solution Approach 1:
The patent combines multiple separate elements (module base, connection strip, mounting structure) into a single integrated base component. This merging reduces the number of parts to manufacture and assemble, lowering manufacturing costs while maintaining the flexibility to configure different module arrangements through the integrated design
