Display Holder Grooves for Water Drainage Near Circuit Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in effectively draining water from the internal components without accumulating it, which can lead to corrosion and damage to the electrical system, even when a waterproof sheet is provided.
Innovation Solution
The electronic device incorporates a holder with grooves extending in the up-down direction on its back, connected to each other, and a through hole in the front panel, allowing water to drain from the gaps between the holder and the display panel to the outside through the front panel's through hole, enhancing drainage efficiency without the need for multiple through holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof sheet is provided to prevent water from reaching the circuit board, then the circuit board is protected from corrosion, but water accumulates between the waterproof sheet and the frame member causing potential damage
Solution Approach 1:
The patent introduces a holder as an intermediary component between the display panel and circuit board. The holder includes grooves that act as a mediator to guide and drain water away from the circuit board area, preventing water accumulation while maintaining the protective function of the waterproof sheet.
Solution Approach 2:
The holder is segmented with multiple grooves that divide the water drainage function into multiple channels. This segmentation allows water to be efficiently directed through separate pathways to the through hole, improving drainage effectiveness while maintaining circuit board protection.
2Productivity
If multiple through holes are provided in the frame member for water drainage, then water drainage efficiency is improved, but the structural integrity and complexity of the frame member increases
Solution Approach 1:
The patent extracts the water drainage function from the frame member by providing the through hole in the front panel instead. The holder with its grooves takes over the water guidance function, allowing the frame member to maintain its structural integrity without multiple holes while achieving efficient water drainage through the single front panel through hole.
3Productivity
If the holder includes grooves connected to each other for water drainage, then water drainage path is established, but the holder structure becomes more complex
Solution Approach 1:
The patent merges multiple groove structures into a single integrated holder component. The grooves are connected to each other within the holder body, combining multiple drainage pathways into one unified structure that maintains simplicity while establishing effective water drainage paths to the front panel through hole.

AI summary
An electronic device includes a display panel including a display surface on a front; a front panel surrounding the display panel; a circuit board that is disposed on a front side of a lower portion of the display panel and housed in the front panel; and a holder provided between the front of the display panel and a back of the circuit board. The holder includes a plurality of grooves each continuously extending in an up-down direction on a back of the holder facing the front of the display panel. The plurality of grooves are formed so as to be connected to each other. The front panel is formed with a through hole facing lower ends of the grooves.
