Camera Shielding Structure Using Sector-Shaped Rotational Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera designs that use a straight track mechanism for shielding the lens to prevent privacy leakage are bulky and difficult to miniaturize, limiting design diversity due to the long motion travel of the shielding piece.
Innovation Solution
A shielding structure with a camera base, a shielding member, and an operating member that rotates around a pivot point via a guiding rail, allowing the shielding member to move in a sector-shaped area, reducing the movement stroke and space occupied, while enabling easy rotation between open and closed states for privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a straight track mechanism is used for the shielding member to block the camera lens, then the camera achieves privacy protection functionality, but the motion travel of the shielding member is long and occupies large space
Solution Approach 1:
The patent applies a sector-shaped rotational path instead of a straight linear track. The shielding member rotates along a curved arc defined by a guiding rail, transforming the linear motion into rotational motion. This curvature-based approach reduces the space required while maintaining the shielding function, as the rotational path fits within a smaller boundary compared to a straight track of equivalent shielding coverage.
Solution Approach 2:
The invention transitions from one-dimensional linear motion along a straight track to two-dimensional rotational motion along a sector-shaped arc. By adding the rotational dimension and using a pivot point with guiding rail constraint, the shielding member achieves the same privacy protection function within a more compact spatial footprint, effectively utilizing angular displacement instead of linear displacement.
2Device complexity
If the shielding member uses a straight track mechanism, then it achieves simple structure, but the long motion travel makes miniaturization difficult
Solution Approach 1:
The guiding rail is designed as a curved arc rather than a straight line, creating a sector-shaped rotational path for the shielding member. This curved geometry allows the shielding member to traverse a shorter distance while still achieving full coverage of the lens, thereby reducing the motion travel length without significantly increasing structural complexity.
3Volume of moving object
If the shielding member rotates around a pivot point along a sector-shaped area, then the movement stroke is reduced and space is saved, but the mechanism becomes more complex
Solution Approach 1:
The shielding member is divided into distinct functional segments: a shielding portion for blocking the lens, a connecting portion for attachment to the operating member, and a pivot point for rotation. This segmentation allows each part to perform its specific function efficiently, with the pivot point enabling compact rotational motion and the guiding rail constraining the path to a sector-shaped area, thereby reducing overall space requirements.
Solution Approach 2:
The guiding rail acts as an intermediary element between the operating member and the shielding member. It translates the linear or rotational motion of the operating member into the precise sector-shaped rotational path of the shielding member, enabling compact motion while maintaining functional reliability without requiring complex direct coupling mechanisms.
4Ease of operation
If a straight track mechanism is used, then the shielding member moves linearly, but it takes up large space and limits camera appearance design diversity
Solution Approach 1:
The sector-shaped rotational path defined by the curved guiding rail allows the shielding member to move along an arc rather than a straight line. This curved motion pattern enables more flexible integration into various camera housing designs, allowing for diverse appearance configurations while maintaining ease of operation through the simple rotational mechanism driven by the operating member.

AI summary
A shielding structure includes a camera base, a shielding member, and an operating member. The camera base is provided with a lens module and a guiding rail. One end of the shielding member is provided with a shielding part, the other end of the shielding member is provided with a connecting part, and a pivot point arranged between the connecting part and the shielding part. The operating member is connected to the connecting part and configured to slide along the guiding rail. Sliding of the operating member along the guiding rail drives the connecting part of the shielding member to move so as to bring the shielding member to rotate around the pivot point.
