Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional indoor electrical wiring in buildings is inefficient, messy, and time-consuming, requiring open slots in concrete structures and leading to potential damage and complex maintenance processes.
Innovation Solution
A heavy-current system and distributor with a PCB board, power transmission copper bars, and quick-connect terminals, allowing for standardized, simplified installation and maintenance by routing power lines through suspended ceilings or partitions, eliminating the need for open slots and using fuse protection for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If open slots are defined on the floor or wall and cable conduits are buried, then the wiring is protected and organized, but the installation process becomes time-consuming and the wall structure is prone to damage
Solution Approach 1:
The patent divides the heavy-current distribution system into modular distributors that can be independently installed and connected. Each distributor handles specific lighting circuits, allowing installation without cutting into wall structures. The system segments the power distribution into manageable units that can be assembled and connected through simple interfaces.
Solution Approach 2:
The patent transitions from traditional wall-embedded wiring to surface-mounted distribution boxes and cable management systems. By moving the distribution components to accessible locations (walls, ceilings) rather than embedding them in concrete structures, the system eliminates the need for open slots and reduces installation complexity while maintaining wiring organization and protection.
2Device complexity
If all cables are led out from a single distribution box below the electricity meter, then the power distribution is simplified, but the wiring becomes messy and maintenance requires powering off all lines
Solution Approach 1:
The patent divides the centralized distribution box into multiple distributed lighting distributors, each handling specific lighting circuits. This segmentation allows cables to be organized by function and location rather than all converging at one point, reducing wiring complexity and enabling isolated maintenance of individual circuits without affecting the entire system.
Solution Approach 2:
The patent introduces intermediate distribution points (lighting distributors) between the main electricity meter and individual lighting circuits. These intermediaries act as local hubs that organize cables and provide access points for maintenance, eliminating the need to trace all cables back to the main distribution box and allowing selective circuit isolation.
3Reliability
If cables are connected using traditional methods with insulation rubbers and screws, then the connections are achieved, but the installation process is tedious and has low efficiency
Solution Approach 1:
The patent replaces traditional mechanical connection methods (screws, insulation rubbers) with integrated connection terminals built into the distributor housing. The connection terminals provide built-in clamping and insulation mechanisms that eliminate the need for separate mechanical fastening components, reducing installation steps and improving efficiency while maintaining connection reliability.
Solution Approach 2:
The patent combines multiple functions (connection, insulation, terminal function) into integrated connection terminals that are part of the distributor structure. This merging eliminates the need for separate insulation rubbers and screw fasteners, as the terminal itself provides all necessary connection and insulation functions in a single component.
