Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective cases for folding screen mobile phones fail to provide effective protection for the hinge part, which is a critical and costly structural component prone to damage from impacts and bumps.
Innovation Solution
A protective case design featuring a front and rear protective case, a soft connecting mechanism, and a hinge protector with magnetic positioning, allowing the hinge protector to securely attach to the front protective case and retract during unfolding, utilizing a combination of soft and hard materials for comprehensive protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If soft leather is used to wrap the hinge part with a flip cover, then the hinge part can be covered, but it cannot effectively protect the hinge part from falling, bumping, and impact
Solution Approach 1:
The patent uses a composite structure combining hard protective case material (PC or ABS) for the main body with soft leather material for the flip cover wrapping. This composite approach provides both structural strength for impact resistance and flexible coverage for the hinge area, resolving the contradiction between coverage and protective capability.
Solution Approach 2:
The protective case is divided into multiple functional segments: a hard protective case for structural support, a soft leather flip cover for wrapping the hinge, and a specifically designed hinge protector component. This segmentation allows each part to specialize in its protective function, with the hinge protector providing targeted reinforcement where needed most.
2Object-affected harmful factors
If a hinge protector is added to provide effective protection, then protection capability is improved, but device complexity increases
Solution Approach 1:
The hinge protector is merged with the existing case structure through the soft connecting mechanism, which integrates it into the overall protective case system. The connecting mechanism uses the existing space and structural elements of the case, avoiding the need for separate independent components and reducing overall complexity.
Solution Approach 2:
The soft connecting mechanism uses flexible material that can bend and deform to accommodate the hinge's movement. This flexible connection allows the hinge protector to be integrated into the case structure without requiring rigid, complex mechanical linkages, thereby simplifying the overall device complexity while maintaining protective function.
3Reliability
If the hinge protector is fixedly connected to provide stable protection, then protection reliability is improved, but ease of operation deteriorates due to interference with folding/unfolding
Solution Approach 1:
The connecting mechanism transitions from a static fixed connection to a dynamic flexible connection that adapts its state based on operation. During folding/unfolding, the soft material deforms to allow movement; during stationary use, it maintains secure attachment. This dynamic behavior resolves the contradiction between stability and operability.
Solution Approach 2:
The mechanical properties of the connecting mechanism change based on operational state. The soft material exhibits different degrees of rigidity and flexibility depending on whether the phone is being operated or is stationary, allowing secure attachment during use while permitting smooth operation during folding and unfolding actions.
