Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting connectors with integrated light-emitting elements face difficulties in manufacturing due to the cumbersome process of identifying and soldering power wires among multiple signal wires, and the light-emitting elements are prone to detachment during handling and molding, leading to reduced production efficiency and increased costs.
Innovation Solution
A lighting connector design featuring a transparent insulating layer and an adapter circuit board with printed power circuits directly connected to the light-emitting element's electrode pins, eliminating the need for separate power wire connections and ensuring the element is securely fixed before molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode pins of the light-emitting element are directly soldered with the power wires among multiple signal wires, then the light-emitting element can be connected to power supply, but the manufacturing process becomes troublesome and time-consuming due to the need to identify and solder each power wire individually
Solution Approach 1:
The patent segments the circuit board into distinct functional areas: a signal wire connection region with multiple signal wire contacts, and a light-emitting element connection region with dedicated power wire contacts. This spatial segmentation allows power wires to be separately identified and connected without confusion among multiple signal wires, improving manufacturing efficiency while maintaining connection reliability.
Solution Approach 2:
The patent introduces an intermediary structure - the circuit board with printed circuit traces - that mediates between the power wires and the light-emitting element. The power wire contacts are connected to the light-emitting element contacts through predetermined circuit traces on the board, eliminating the need to directly identify and solder power wires to the element, thus improving manufacturing efficiency.
2Ease of manufacture
If the light-emitting element is not fixed before injection molding, then the manufacturing process is simpler, but the light-emitting element is likely to detach during transfer due to collision or pulling, reducing the ratio of good products
Solution Approach 1:
The patent applies preliminary action by fixing the light-emitting element to the circuit board before the injection molding process. The element is secured in its predetermined position on the board with proper orientation, ensuring it remains stable during subsequent handling, transfer, and molding operations, thereby preventing detachment and reducing defective products.
3Device complexity
If conventional connectors are used without additional light-emitting elements, then the structure is simpler, but users cannot judge whether the connector is in use or not in appearance
Solution Approach 1:
The patent applies the color change principle by incorporating a light-emitting element that emits visible light when activated. The light emission provides clear visual feedback to users about the connector's usage status, transforming an invisible electrical state into a visible optical signal without significantly complicating the overall connector structure.

Function Achieved in This Case
Simplifies the manufacturing process by eliminating the need for manual power wire identification and enhances product reliability by securely attaching the light-emitting element, allowing users to visually confirm the connector's usage status and reducing manufacturing defects.
Implementation Method 1
At least one light-emitting element is soldered on the adapter circuit board. Two electrode pins of the light-emitting element are respectively connected to a set of printed power circuits of the adapter circuit board. After turned on, the light-emitting element emits light which goes through the transparent insulating layer to outer side.
