Phone Camera Protective Frame Hinge Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone camera lens protection frames have complex hinge structures that are difficult to install and provide poor stability when used as a support bracket.
Innovation Solution
A protective frame with a simplified hinge structure that includes a shaft positioning block, shaft sleeve, and pivot shafts, allowing for quick assembly and stable positioning of the upper frame relative to the lower frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional hinge structure with shaft and brackets is used to connect upper and lower frames, then the protective frame can be assembled, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple hinge components (shaft, brackets, positioning elements) into an integrated hinge structure where the shaft directly engages with positioning grooves and ribs on the frames. This merging of functions into a unified structure eliminates the need for separate brackets and complex assembly steps, thereby simplifying the overall hinge design and reducing assembly complexity
Solution Approach 2:
The hinge structure is segmented into distinct functional elements: the shaft for rotation, positioning grooves for alignment, and ribs for structural support. This segmentation allows each element to be optimized independently while maintaining overall simplicity, enabling easy manufacturing and assembly without requiring complex integrated components
2Ease of operation
If a single-axis hinge structure is used to support the mobile phone, then the upper frame can be flipped, but the stability is poor and the angle is easily altered
Solution Approach 1:
The patent transitions from a single-axis hinge to a dual-axis hinge structure, adding another rotational dimension. The first pivot shaft enables rotation in one plane while the second pivot shaft enables rotation in a perpendicular plane. This dimensional expansion provides two degrees of freedom, allowing the upper frame to be flipped and positioned at various angles while maintaining stability through the combined constraint of both axes

AI summary
The present invention provides a protective frame for phone camera, including: a lower frame fixedly mountable on a phone case; and an upper frame connected to the lower frame through a hinge structure including: a shaft positioning block; a shaft sleeve; a pair of shaft brackets; and a first pivot shaft. The shaft sleeve has a positioning strip and the hollow channel has a positioning groove coupled to the positioning strip such that the shaft sleeve can be assembled in the hollow channel in a quickly detachable manner. A front end of the pivot shaft is configured to pass through at least one shaft hole of the shaft brackets and inserted into an axial channel of the shaft sleeve by means of transition fit such that the upper frame is rotatable while capable to maintain a stable state when being flipped at a desired angle relative to the lower frame.
