Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process of mounting a connector on the lower surface of a printed circuit board after mounting light sources and components on the upper surface increases processing time and cost due to the double mounting process.
Innovation Solution
A connector is mounted on the upper surface of the printed circuit board, providing electrical connections between the upper and lower surfaces, and includes terminals that connect adjacent portions of the printed circuit board, allowing for detachable coupling to wires for connecting the printed circuit board to other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector is mounted on the lower surface of the printed circuit board after mounting light sources and components on the upper surface, then the electrical connection between upper and lower surfaces is achieved, but the processing time and cost increase due to double mounting process
Solution Approach 1:
The patent inverts the conventional mounting sequence by mounting the connector on the upper surface of the printed circuit board first, before mounting the light sources and components. This reversal eliminates the need for a second mounting process on the lower surface, thereby reducing processing time and cost while maintaining reliable electrical connections through the connector terminals that extend through the board.
2Reliability
If the connector is mounted on the lower surface of the printed circuit board, then the electrical connection is provided, but the device complexity increases due to multiple mounting steps
Solution Approach 1:
The patent merges the connector mounting operation with the initial component mounting phase. By mounting the connector on the upper surface along with the light sources and components in a single process step, the overall device complexity is reduced. The connector terminals extend through the printed circuit board to provide electrical connections, eliminating the need for separate lower surface mounting operations.
3Productivity
If the connector is mounted on the upper surface of the printed circuit board, then the processing time and cost are reduced, but the connector must extend through the board to provide lower surface connections
Solution Approach 1:
The connector is segmented into multiple functional parts: a body portion mounted on the upper surface, terminals that extend through the printed circuit board to provide electrical connections, and a lower surface interface portion. This segmentation allows the connector to be mounted on the upper surface in a single operation while still providing the necessary through-board electrical connections, balancing simplified mounting with functional requirements.

AI summary
A display apparatus includes a display panel, a printed circuit board defining an upper surface, a lower surface opposite the upper surface, and a through-hole, a plurality of light sources mounted on the upper surface of the printed circuit board and configured to emit light to the display panel, and a connector inserted into the through-hole on the upper surface of the printed circuit board. The connector includes a connector body inserted into the through-hole, and a plurality of connector terminals disposed in proximity to the upper surface of the printed circuit board. The connector terminals are configured to electrically connect the connector body to a portion of the printed circuit board, and may in certain embodiments connect a first portion of the printed circuit board on one side of the connector body to a second portion of the printed circuit board on an opposite of the connector body.
