Modular Terminal Block System with Integrated Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection systems for appliances lack flexibility in modulating the number of connection terminals, requiring additional parts and intermediate supports, which complicates manufacturing and usage.
Innovation Solution
An electrical device with an elongated insulating support and removable terminal blocks, where the support has integrated connection means and a U-channel portion, allowing for direct addition of terminal blocks without intermediate parts, using snap-fastening and sliding mechanisms for easy assembly and reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed terminal blocks are used, then the connection capacity is determined at manufacture, but the flexibility to modulate the number of terminals is poor
Solution Approach 1:
The terminal block system is divided into a support structure and multiple removable terminal blocks. Each terminal block can be independently added or removed from the support, allowing the connection capacity to be modulated according to needs without changing the entire system.
Solution Approach 2:
The support structure is designed with universal mounting features that can accommodate different numbers and configurations of terminal blocks. The same support can serve multiple functions by accepting various terminal block arrangements.
2Quantity of substance
If additional terminal blocks are added using intermediate supports, then the connection capacity increases, but the number of parts and manufacturing complexity increases
Solution Approach 1:
The support structure integrates the mounting function and the terminal block housing into a unified design. The support itself forms part of the terminal block assembly, eliminating the need for separate intermediate supports or mounting brackets.
Solution Approach 2:
The support structure serves multiple functions simultaneously: it provides mechanical support, electrical insulation, mounting interfaces for terminal blocks, and structural integration. This multi-functionality reduces the need for additional specialized parts.
3Adaptability or versatility
If removable terminal blocks are used, then the flexibility to adjust connection capacity is improved, but the assembly complexity increases
Solution Approach 1:
The terminal block system is segmented into removable modules that can be independently handled and installed. Each terminal block is a self-contained unit that simplifies the assembly process compared to integrated fixed designs.
Solution Approach 2:
The terminal blocks are designed to be dynamically addable or removable from the support structure during operation or maintenance, allowing flexible adjustment without requiring system disassembly or complex installation procedures.
