Electronic Device Protrusion Sealing for Reduced Gasket Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waterproof designs for outdoor electronic devices rely on aging-prone waterproof gaskets, necessitating frequent replacements and increased costs.
Innovation Solution
An electronic device design featuring a housing with protrusion portions and detachable covering members that allow wires to pass through, providing adjustable protection against water and dust ingress by switching between passing and blocking orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof gaskets are used in current waterproof designs, then waterproof performance is achieved, but the gaskets are prone to aging and require frequent replacement, increasing costs
Solution Approach 1:
The waterproof sealing function is segmented from the traditional gasket component and integrated into the housing structure through protrusion portions and corresponding grooves. This segmentation eliminates the separate gasket component that ages and fails, while maintaining waterproof performance through the structural design of the housing itself.
Solution Approach 2:
The aging-prone waterproof gasket is extracted and removed from the design. Instead, the waterproof function is achieved through the housing structure's protrusion portions and grooves that physically block water ingress without requiring separate sealing components.
2Object-affected harmful factors
If waterproof gaskets are used to protect internal circuits, then protection against water and dust is provided, but when gaskets are partially damaged, the entire set must be replaced, increasing costs
Solution Approach 1:
The housing is segmented into modular components with protrusion portions that can be independently replaced. If one protrusion portion is damaged, only that specific component needs replacement rather than the entire housing set, reducing repair costs while maintaining protection against water and dust ingress.
3Object-affected harmful factors
If traditional waterproof designs are used, then protection is provided, but the designs are complex and require multiple components
Solution Approach 1:
The waterproof sealing function is merged with the housing structure itself. The protrusion portions and grooves are integrated directly into the housing, eliminating the need for separate waterproof gaskets and other dedicated sealing components, thereby reducing overall device complexity while maintaining protection.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical support, defines the device geometry, and simultaneously provides waterproof sealing through its protrusion portions and grooves. This multi-functionality eliminates the need for separate dedicated waterproofing components.

AI summary
An electronic device includes a housing, a first protrusion portion and a first covering member. The housing has a bottom portion. The first protrusion portion is arranged on the bottom portion of the housing, wherein the first protrusion portion has a first groove through which a first wire passes. The first covering member detachably covers the first protrusion portion, wherein the first covering member has a first opening. In a first position, the first opening of the first covering member is used for allowing the first wire to pass through.
