Rotatable Buckle Ring Case for Device Support and Wireless Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device supports, such as stands, are inconvenient to carry and occupy additional space, while prolonged holding of large and heavy devices leads to user fatigue.
Innovation Solution
An electronic device protective case with a rotatable buckle ring that transitions between a stowed and supporting state, integrated into the housing, providing support without the need for additional accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate stand is used to support the electronic device, then the device can be supported without user holding, but the user must carry an additional accessory which increases portability burden
Solution Approach 1:
The support function is merged with the protective case by integrating a rotatable buckle ring into the case structure. The buckle ring serves dual purposes: securing the device within the case and providing stand functionality when rotated to a supporting position. This eliminates the need for a separate stand accessory.
Solution Approach 2:
The buckle ring is designed to perform multiple functions: it acts as a securing mechanism to hold the device in the case, and simultaneously serves as a support stand when rotated to a specific angle. This multi-functionality reduces the number of separate accessories needed.
2Ease of operation
If a separate stand is used to support the electronic device, then the device can be supported without user holding, but the stand occupies additional space during carrying
Solution Approach 1:
The support function is merged with the protective case by integrating a rotatable buckle ring into the case structure. The buckle ring serves dual purposes: securing the device within the case and providing stand functionality when rotated to a supporting position. This eliminates the need for a separate stand accessory.
Solution Approach 2:
The buckle ring is nested within the case structure when in its stowed position, occupying minimal space. When needed, it rotates outward to provide support functionality, then returns to its compact nested position within the case, minimizing carried volume.
3Ease of operation
If the user holds the electronic device for prolonged periods, then the device remains supported, but the user experiences gripping fatigue
Solution Approach 1:
The buckle ring is designed to be rotatable, allowing dynamic adjustment between a stowed position (where it fits against the case surface) and a supporting position (where it extends outward to provide stand functionality). This dynamic capability enables the user to switch between holding and supported modes as needed.

AI summary
An electronic device protective case, including a housing provided with an electronic device accommodation chamber, a fixing seat, where the fixing seat is fixedly connected to the housing; and a buckle ring, where the buckle ring is rotatably connected to the fixing seat. When the buckle ring rotates relative to the fixing seat to fit with a surface of the housing, the buckle ring is in a stowed state, and when the buckle ring rotates relative to the fixing seat to unfold from the surface of the housing, the buckle ring is in a supporting state. This electronic device protective case includes the fixing seat disposed on the housing, thereby mounting the rotatable buckle ring. In the stowed state, the buckle ring can achieve a wireless charging function. In the supporting state, the buckle ring can function as a stand.
