Protective Cover Sealing Ring and Rotating Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal protective covers have poor waterproof and dustproof performance, are single-function, and are inconvenient for users to hold due to their increasing size.
Innovation Solution
A mobile terminal protective cover comprising a lower cover, an upper cover, a sealing ring, a support assembly, and a hand strap, where the sealing ring enhances waterproof and dustproof performance, the support assembly allows for standing and folding, and the hand strap provides convenience for holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing ring is added between the upper cover and lower cover to improve waterproof and dustproof performance, then the sealing performance is improved, but the device complexity increases
Solution Approach 1:
A sealing ring is introduced as an intermediary component between the upper cover and lower cover to achieve waterproof and dustproof sealing. The sealing ring acts as a mediator that fills the gap between the two covers, preventing water and dust penetration while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the protective cover is made larger to accommodate bigger mobile terminals, then the adaptability to different device sizes is improved, but the ease of operation deteriorates due to inconvenience for users to hold
Solution Approach 1:
The support assembly is designed to be rotatable, allowing it to switch between an unfolded state for providing standing support and a folded state for reducing overall size. This dynamic transformation enables the protective cover to adapt to different usage scenarios while maintaining portability and ease of holding.
3Device complexity
If the protective cover only provides basic protection, then the device complexity is kept simple, but the adaptability to different use scenarios deteriorates
Solution Approach 1:
The protective cover integrates multiple functions: basic protection, waterproofing, dustproofing, and a rotatable support assembly that enables standing mode for hands-free viewing. This multi-functional design allows a single device to serve multiple purposes without significantly increasing structural complexity.

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 improves the waterproof and dustproof performance, adds multifunctionality by allowing the cover to stand and fold, and enhances user convenience through the hand strap, addressing the limitations of existing protective covers.
Implementation Method 1
The hand strap has elasticity

AI summary
The mobile terminal protective cover includes a lower cover, an upper cover, a sealing ring arranged between the upper cover and the lower cover, a hand strap, and a support assembly arranged between the lower cover and the hand strap. The upper cover and the lower cover are enclosed to form a protective groove accommodating a mobile terminal. The upper cover and the lower cover are connected and sealed through the sealing ring. The support assembly is rotatably connected to a rear side of the lower cover. The support assembly is switched between an unfolded state and a folded state by rotating the support assembly. In the unfolded state, the support assembly supports the mobile terminal protective cover to stand. In the folded state, the support assembly is folded on the lower cover. The hand strap having elasticity is fixed to the rear side of the lower cover.
