Detachable Pushbutton Sealing Structure for Dustproof Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-protection pushbutton structures face issues with dust and moisture accumulation, which hinder operation and maintenance, as the design does not allow for easy cleaning or replacement of components without compromising protection.
Innovation Solution
A detachable pushbutton structure with a cap assembly and protective ring that seals the receiving space, allowing for easy cleaning and maintenance by blocking dust and moisture when the pushbutton is removed, and enabling easy replacement of the pushbutton with different markings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pushbutton is securely connected to the support seat to prevent detachment, then protection against dust and moisture is improved, but ease of cleaning and maintenance deteriorates
Solution Approach 1:
The pushbutton structure is divided into separable components: the pushbutton (9) can be detached from the support seat (7), and the cap assembly (3) can be removed from the penetrating hole (21). This segmentation allows maintenance personnel to access the receiving space (11) for cleaning without compromising the protective sealing when components are assembled, thereby resolving the contradiction between secure protection and ease of maintenance.
2Ease of operation
If the pushbutton is made detachable for easy replacement, then ease of operation is improved, but protection against dust and moisture deteriorates
Solution Approach 1:
The cap assembly (3) acts as an intermediary sealing element that covers the penetrating hole (21) when the pushbutton (4) is removed. This intermediary component maintains the protective barrier against dust and moisture intrusion even when the pushbutton is detached for replacement, thus resolving the contradiction between ease of replacement and protection against harmful factors.
3Reliability
If the receiving space is sealed to prevent accumulation, then reliability is improved, but ease of maintenance deteriorates
Solution Approach 1:
The sealing system is designed with separable components - the cap assembly (3) can be independently removed from the support seat (7) to provide access to the receiving space (11) for maintenance. When assembled, it maintains the sealed environment that prevents accumulation of dust and moisture. This segmentation allows the system to achieve both reliability through sealing and ease of maintenance through component separability.

AI summary
A detachable pushbutton structure includes a case seat which is formed with an internal receiving space for receiving a base seat and a linking member. The base seat has multiple contact legs. The linking member is drivable to control the respective contact legs to form different conducting states. A support seat connected with the linking member and has an internal penetrating hole. A light-emitting member is received in the penetrating hole and connected with the base seat. A connected section is disposed on an outer side of the support seat. A cap assembly can be tightly capped on the penetrating hole of the support seat. A pushbutton is capped on the cap assembly and has a connection section detachably connected with the connected section. A protective ring securely connected between an inner circumference of the receiving space and an outer circumference of the support seat.
