Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-structure electric junction box is used, then the structural stability is maintained, but the versatility to adjust the number of mounted components is limited
Solution Approach 1:
The electric junction box is divided into multiple detachable block parts, each containing a specific number of terminal holes and mounting positions. These modular blocks can be selectively assembled or disassembled to adjust the total number of mounted components, enabling versatility while maintaining simple individual block structures
Solution Approach 2:
The junction box structure transitions from a fixed configuration to a dynamic, reconfigurable system. The detachable block parts allow the structure to be modified by adding or removing blocks according to component mounting requirements, providing adaptability without permanently increasing structural complexity
2Quantity of substance
If the number of mounted fuses and components is increased, then the electrical functionality is enhanced, but the device complexity and assembly difficulty increase
Solution Approach 1:
Instead of assembling numerous individual components into a single complex structure, the system segments components into modular blocks. Each block is pre-configured with terminals and mounting features, allowing multiple blocks to be easily combined to achieve the desired number of components without proportionally increasing assembly difficulty
Solution Approach 2:
Multiple terminal holes and mounting positions are merged into integrated block parts that can be coupled together. This combining approach allows the system to scale the number of components by simply adding blocks rather than individually assembling each component, reducing overall assembly complexity
3Adaptability or versatility
If a modular detachable structure is implemented, then the versatility and customizability are improved, but the connection stability and reliability may be affected
Solution Approach 1:
The coupling structure between block parts employs asymmetric design with coupling protrusions and corresponding coupling recesses. This asymmetric configuration ensures proper alignment and secure connection when blocks are assembled, maintaining connection stability while allowing the modular structure to be easily disassembled and reconfigured for customization

AI summary
A connecting block assembly includes a plurality of connecting block parts for connecting electric components which are assembled to each other. Each of the connecting block parts includes a plurality of conductive terminals having electric connecting portions and extended portions extended from the electric connecting portions respectively, and an insulating resin member which fixes the plurality of terminals at positions of the extended portions. A coupling portion is formed on one side wall of the resin member in a coupling direction being perpendicular to both of an extending direction of the extended portions and an arranging direction of the plurality of terminals, and a coupled portion having a shape to be coupled to the coupling portion is formed on the other side wall of the resin member in the coupling direction.
