Rotating Waterproof Cover Seal for Expansion Interface Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof structures for portable electronic devices, such as those meeting the IP67 standard, fail to effectively seal expansion interfaces, and require inconvenient screw loosening for access, which is inadequate for users in wet environments.
Innovation Solution
A waterproof structure featuring a rotating cover with an elastic pad and protrusion structures that compress into waterproof grooves to form a seal, preventing water and dust ingress through expansion interfaces, and a portable electronic apparatus design incorporating this structure for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof structure is used to seal expansion interfaces, then water and dust impermeability is improved, but the ease of accessing expansion interfaces deteriorates
Solution Approach 1:
The waterproof cover is designed to be rotatable relative to the housing, transitioning between an open state (allowing access to expansion interfaces) and a closed state (providing waterproof sealing). This dynamic mechanism resolves the contradiction by enabling the structure to adapt its state based on operational needs.
Solution Approach 2:
An elastic pad with protrusion structures is introduced as an intermediary element between the waterproof cover and the housing. The protrusions insert into corresponding grooves to form a seal when the cover is closed, providing reliable waterproofing while allowing for easy opening and closing without tools.
2Reliability
If screws are used to fasten the waterproof structure, then the sealing reliability is improved, but the ease of operation deteriorates due to requiring tools for loosening
Solution Approach 1:
The traditional screw-based mechanical fastening system is replaced with a rotatable cover mechanism that uses elastic protrusions engaging with grooves. This substitution eliminates the need for tools while maintaining sealing reliability through the elastic seal design.
Solution Approach 2:
The elastic pad with protrusion structures provides self-aligning and self-sealing functionality. When the cover is rotated to the closed position, the protrusions automatically insert into the grooves and compress the elastic material to form a seal, without requiring external tools or complex fastening operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliable, user-friendly waterproofing system that keeps devices impermeable to dust and water, even in harsh conditions, while allowing easy access to expansion interfaces without the need for screw loosening.
Implementation Method 1
The elastic pad comprises at least one protrusion structure, and the at least one protrusion structure is capable of inserting into a waterproof groove on the housing corresponding to the protrusion structure. When the cover is rotated to close the housing, the cover is capable of compressing the elastic pad to form a seal between the at least one protrusion structure and the waterproof groove.
