Camera Strap Locking Mechanism With Dual Locking and Width Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera strap locking mechanisms have a limited adaptation range, require complex operations for replacement, and lack a stable double fixing mechanism, leading to potential safety issues during quick hanging and increased risk of camera detachment.
Innovation Solution
A strap locking mechanism with a primary and secondary locking mechanism, where the secondary locking is achieved through a rotating pressing plate that controls the secondary locking mechanism to form a locking force or release force, using a driving mechanism to rotate and lock or unlock the strap, and a hook with adjustable clamping grooves for various strap widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single locking mechanism is used, then the device complexity is reduced, but the reliability of strap fixation deteriorates
Solution Approach 1:
The locking mechanism is divided into two independent parts: a primary locking mechanism (buckle and strap assembly) and a secondary locking mechanism (screw and pressing plate assembly). Each locking mechanism performs a specific locking function, and the two work together to achieve reliable strap fixation. The primary locking mechanism provides initial clamping, while the secondary locking mechanism provides additional securement, thereby improving overall reliability without requiring a completely complex integrated system.
Solution Approach 2:
The secondary locking mechanism acts as a backup or cushioning measure against the potential failure of the primary locking mechanism. By pre-installing the secondary locking mechanism, the system ensures that even if the primary mechanism fails under large forces, the camera remains securely attached through the secondary mechanism, thus preventing camera detachment before it can occur.
2Adaptability or versatility
If a fixed clamping structure is used, then the manufacturing precision is improved, but the adaptability to different strap widths deteriorates
Solution Approach 1:
The pressing plate is designed to be movable rather than fixed, allowing it to be adjusted to different positions along the base. This dynamic adjustment capability enables the clamping structure to adapt to various strap widths while maintaining precise clamping force through the screw mechanism. The pressing plate can be positioned at different locations to accommodate different strap thicknesses and widths, thereby achieving both adaptability and manufacturing precision.
3Ease of operation
If a spherical connection structure is used, then the ease of operation is improved, but the reliability of connection deteriorates
Solution Approach 1:
The connection system is segmented into multiple independent connection points: the buckle-strap connection and the pressing plate-base connection. Instead of relying on a single spherical connection that may detach under force, the system distributes the connection functions across multiple secured points. The pressing plate with its screw mechanism provides a separate, more reliable connection that prevents the camera from detaching even if one connection point fails.
