Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal blocks require significant space for light guiding structures to indicate electrical connection status, making it difficult to reduce the overall volume of the terminal block.
Innovation Solution
A terminal block design that integrates LEDs on a circuit board within a docking chamber of an insulation base, allowing illumination through through holes in the insulation base, eliminating the need for external light guiding structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light guiding structures are arranged on the circuit board and insulation base to indicate electrical connection status, then the indication function is achieved, but a large part of space in the terminal block is occupied by these structures
Solution Approach 1:
The patent merges the light guiding function with the insulation base structure itself. The insulation base is designed with light guiding structures that are integrated into its body, allowing light to pass through designated areas to indicate connection status. This eliminates the need for separate external light guiding components, thereby reducing the overall volume of the terminal block while maintaining the indication function.
Solution Approach 2:
The insulation base serves multiple functions: it provides electrical insulation, structural support, and now also light guiding for indication. By making the insulation base multi-functional, the patent reduces the number of separate components needed, thereby decreasing the overall volume occupied by light guiding structures while maintaining reliable electrical connection indication.
2Reliability
If light guiding structures are arranged on the circuit board and insulation base, then the light source can be guided to the coupling opening for indication, but the volume of the terminal block becomes difficult to decrease
Solution Approach 1:
The patent combines the light guiding function with the insulation base structure. The insulation base incorporates light guiding features directly into its design, allowing the light source to be guided to the coupling opening through the insulation base itself rather than requiring separate light guiding structures on both the circuit board and insulation base, thereby reducing overall volume.
