Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED driving power technologies face issues with poor waterproofing, key switch damage, and limited flexibility in adding multiple key switches due to structural design limitations, particularly in vertical driving power configurations where the switch is prone to tilting or falling off and has poor sealing efficacy.
Innovation Solution
A vertical multi-function driving power design featuring an integrally formed shell with a side-mounted key hole, a vertically arranged key column, and a sealing cover with a 'Y'-shaped notch clamping mechanism, allowing for improved sealing, reduced risk of key switch damage, and flexibility in adding multiple key switches by dispersing pressure and ensuring stable mounting of the circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vertical driving power with a key switch mounted on the circuit board is used, then the waterproof function is improved, but the key switch is prone to tilting or falling off due to small force-receiving area at the welding part
Solution Approach 1:
The key switch mounting position is changed from the circuit board plane to the side surface of the shell, creating a three-dimensional spatial separation. The key switch is mounted on the side surface of the shell rather than on the circuit board, which allows the welding part to have a larger force-receiving area and prevents tilting or falling off while maintaining waterproof functionality.
2Device complexity
If the key switch is mounted on the circuit board with limited assembly space, then the structure is compact, but multiple groups of key switches cannot be added due to space constraints
Solution Approach 1:
The key switch mounting location is moved from the two-dimensional circuit board surface to the three-dimensional side surface of the shell. This spatial relocation provides additional mounting space that allows multiple groups of key switches to be added without increasing circuit board complexity or compromising structural compactness.
3Reliability
If a seal is mounted in a hole on the tail cover to seal the hole, then some waterproof function is achieved, but rainwater can still flow into the interior through the gap between the seal and the edge of the hole
Solution Approach 1:
The sealing structure is divided into multiple segments: the seal itself, the first extension portion, and the second extension portion. These segmented components work together to create multiple barriers against water infiltration, with each segment contributing to the overall waterproof performance by addressing different aspects of potential water entry paths.
Solution Approach 2:
The first and second extension portions protrude beforehand to provide protective coverage over the seal and key hole area. These extension portions act as preliminary barriers that prevent rainwater from reaching the gap between the seal and hole edge, cushioning against potential water infiltration before it can occur.
4Reliability
If an integrally formed shell with side-mounted key hole is used, then the sealing and waterproof performance is improved, but the structure becomes more complex
Solution Approach 1:
The shell, key hole, first extension portion, and second extension portion are integrated into a single integrally formed structure. This merging of components eliminates the need for separate sealing elements and assembly steps, improving waterproof performance while actually simplifying the manufacturing process and reducing overall structural complexity despite the enhanced functionality.

Implementation Method 1
the upper surface of the mounting block gradually extends straight upward from the opening end of the shell to the closed end of the shell, and forms an included angle of 0 to 45 degrees with a lower side surface of the shell
Implementation Method 2
clamping blocks are arranged symmetrically on the inner side surfaces of the end cover, the clamping blocks each have a 'Y'-shaped notch, when the opening end of the shell and the end cover are connected together, the 'Y'-shaped notch of the clamping block is clamped with one end of the circuit board

AI summary
The present invention relates to the field of driving power technologies, and in particular, to a vertical multi-function driving power, which includes an integrally formed shell, an end cover, a waterproof socket, a sealing cover, and a circuit board. One end of the shell is closed and the other end is provided with an opening. The opening end of the shell is detachably connected to an inner side surface of the end cover, the waterproof socket is integrally formed on an outer side surface of the end cover, at least one key hole penetrates through an upper side surface of the shell, and the sealing cover is mounted in the key hole to seal it. The circuit board is provided with a key column perpendicular to a substrate, and two inner side surfaces adjacent to the side surface where the key hole is located inside a cavity of the shell are provided with mounting blocks symmetrically. Clamping blocks are arranged symmetrically on the inner side surfaces of the end cover, and the clamping blocks each have a “Y”-shaped notch. The vertical multi-function driving power provided by the present invention has desirable waterproof and moisture-proof effects, and can effectively solve the problems that the circuit board is not easy to mount, the sealing cover is easy to fall off, and multiple groups of key switches cannot be additionally arranged.
