Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In thin flat panel displays, printed circuit boards (PCBs) are prone to electrical short circuits and bending due to close proximity with LCD panels and housing cases, and existing gap supporters fail to securely attach insulation sheets, requiring manual labor and reducing productivity.
Innovation Solution
A gap supporter with a metal thin-film surface for soldering, a coupling groove, and an anti-separation part to securely attach an insulation sheet to the PCB, allowing for automated mass production and efficient insulation sheet coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the PCB is positioned close to the LCD panel to reduce display thickness, then the display device becomes thinner, but electrical short circuits occur between the PCB and housing case
Solution Approach 1:
The patent introduces a gap supporter as an intermediary component between the PCB and housing case. This gap supporter includes a support body with a first surface contacting the PCB and a second surface contacting the housing case, maintaining a predetermined gap to prevent electrical short circuits while enabling closer positioning of the PCB to the LCD panel.
2Volume of moving object
If the PCB is positioned close to the LCD panel, then the display device becomes thinner, but the PCB bends due to height differences of mounted electronic elements
Solution Approach 1:
The gap supporter acts as a mediator between the PCB and housing case, providing uniform support through its support body. The support body includes a support portion contacting the PCB and maintains a predetermined gap, preventing PCB bending caused by height differences of mounted electronic elements while enabling thinner display device design.
3Length of stationary object
If a conventional gap supporter is used, then the gap is maintained, but the insulation sheet cannot be firmly secured and manual work is required
Solution Approach 1:
The patent combines the gap supporter with an insulation sheet into an integrated assembly. The insulation sheet is coupled to the support body of the gap supporter, forming a unified structure that maintains the gap while providing firm securing capability. This integration eliminates the need for separate manual insulation sheet attachment operations.
Solution Approach 2:
The insulation sheet is pre-coupled to the gap supporter during gap supporter manufacturing, rather than being attached separately during final assembly. This preliminary action ensures the insulation sheet is firmly secured in advance, eliminating the need for manual work during productivity-critical assembly operations.
4Ease of manufacture
If the insulation sheet is not firmly secured, then assembly is simpler, but the insulation sheet separates and fails to protect the PCB
Solution Approach 1:
The insulation sheet and gap supporter are merged into a single integrated assembly through coupling mechanisms. The support body includes a coupling portion that firmly secures the insulation sheet, ensuring reliable retention while maintaining manufacturing simplicity through the integrated design.
Solution Approach 2:
The insulation sheet is nested within or coupled to the support body structure of the gap supporter. This nesting arrangement allows the insulation sheet to be firmly secured within the gap supporter's structure, preventing separation while maintaining assembly simplicity through the integrated nested design.

AI summary
The present invention relates to a gap supporter for a printed circuit board, and a package including a gap supporter for a printed circuit board and an insulation sheet coupled thereto. A gap supporter for a printed circuit board includes a fixed body part which has a metal thin-film formed on the surface of the lower end thereof, and is fixed to one surface of the printed circuit board by soldering of the metal thin-film; a clamping groove formed in a groove shape on the fixed body part, and having an insulation sheet inserted and clamped thereto to protect an element on one surface of the printed circuit board; and an anti-separation part formed on the other end of the fixed body part so as to be defined by the clamping groove, so as to fix the insulation sheet and prevent the insulation sheet from being separated.
