Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing central electrical boxes require a large number of terminals and high costs, with printed wiring occupying circuit board space and increasing current carrying load.
Innovation Solution
A terminal with a first termination part, a second termination part, and a bending part connected between them, allowing the terminal to be mounted on a circuit board with one termination part passing through, reducing the need for multiple terminals and wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple terminals and printed wiring are used to connect electronic devices on both sides of the circuit board, then electrical connection is achieved, but the number of terminals increases and cost increases
Solution Approach 1:
The patent merges multiple separate terminals and printed wiring into a single integrated terminal structure. The terminal includes a first termination part, a second termination part, and a bending part that connects them, forming one unified component that performs the electrical connection function between both sides of the circuit board, thereby reducing the total number of terminals required
Solution Approach 2:
The patent utilizes the third dimension by having the terminal pass through the circuit board from one side to the other. The bending part is bent by a predetermined angle (such as 90 degrees) relative to the first and second termination parts, allowing the terminal to traverse through the board thickness and establish connections on both sides, effectively using vertical space to reduce horizontal complexity
2Reliability
If printed wiring is used to connect terminals on the circuit board, then electrical connection is achieved, but the wiring occupies circuit board area and increases current carrying load
Solution Approach 1:
The patent extracts the electrical connection function from the printed wiring layer of the circuit board and relocates it to a separate terminal component. The terminal serves as an independent connection element that passes through the circuit board, removing the need for printed wiring traces and freeing up valuable circuit board area for other components or routing
3Reliability
If multiple terminals and printed wiring are used, then electrical connection is achieved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple separate components (multiple terminals and printed wiring) into a single integrated terminal structure. This consolidation reduces the total component count, simplifies the assembly process, and lowers manufacturing costs by reducing the number of parts that need to be sourced, managed, and assembled
Solution Approach 2:
The terminal is designed as a multi-functional component that simultaneously provides mechanical support, electrical connection, and structural integration. The single terminal structure performs the functions that previously required multiple separate terminals and wiring, improving manufacturing efficiency and reducing overall system cost

AI summary
A terminal used to be mounted on a circuit board. The terminal includes: a first termination part; a second termination part; and a bending part connected between the first termination part and the second termination part. The bending part is bent by a predetermined angle relative to the first termination part and the second termination part, so that the first termination part and the second termination part are staggered by a predetermined distance along a direction transverse to a direction of inserting the terminal to the circuit board. When the terminal is mounted on the circuit board, one of the first termination part and the second termination part passes through the circuit board, so that two electronic devices located on both sides of the circuit board can be directly electrically connected through the terminal.
