Quick-Release Plate Locking Structure to Prevent Camera Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-assembly plates for photographic and digital products tend to loosen easily during use, posing a risk of accidental detachment and equipment damage due to constant motion and shaking, especially in dynamic shooting scenarios.
Innovation Solution
An anti-loosening and anti-rotation quick-assembly plate featuring a storage groove with a large screw, connection and positioning holes, and a fastener (small screw) for secure attachment, along with anti-slip silicone pads to enhance stability and prevent loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional quick-assembly plate is secured to photographic equipment using a screw, then the mounting process is quick and convenient, but the screw tends to loosen easily during use due to constant motion and shaking
Solution Approach 1:
The fastening system is divided into multiple independent components: a large screw for primary fastening, multiple small screws for secondary reinforcement, connection holes in the large screw head, and positioning holes in the plate. This segmentation creates a multi-stage locking mechanism where each component contributes to preventing loosening, while maintaining the quick-assembly benefit through modular design.
Solution Approach 2:
The quick-assembly plate is pre-equipped with connection holes in the large screw head and positioning holes in the plate body before mounting occurs. These features are built into the structure in advance, allowing the operator to quickly engage the fastening system without complex assembly steps, thus maintaining ease of operation while enabling enhanced reliability through pre-positioned reinforcement points.
2Strength
If a large screw is used to secure the quick-assembly plate, then the initial fastening strength is improved, but the screw is still prone to loosening under vibrations and motion
Solution Approach 1:
The solution merges multiple fastening elements (large screw + multiple small screws) into a unified fastening system. The small screws are positioned to work in conjunction with the large screw, creating a composite fastening structure where the combined effect of all screws provides both high initial strength and superior anti-loosening performance under vibrations and motion.
Solution Approach 2:
The fastening system uses a composite approach combining different screw sizes and functions. The large screw provides primary clamping force, while the smaller screws provide additional reinforcement at critical points. This composite fastening structure leverages the strengths of different screw configurations to achieve both high strength and reliability against loosening.
3Reliability
If multiple fastening components are added to prevent loosening, then the anti-loosening performance is improved, but the device complexity increases
Solution Approach 1:
The quick-assembly plate design integrates multiple functions into unified components. The large screw serves both as the primary fastening element and as a carrier for connection holes that accept small screws. The plate body incorporates positioning holes that guide and support the fastening system. This multi-functionality reduces the need for separate dedicated components, thereby improving reliability without proportionally increasing complexity.

AI summary
This application belongs to the technical field of fittings for photography and video recording and digital products and provides an anti-loosening and anti-rotation quick-assembly plate for photographic and digital products, including a quick-assembly plate and a large screw. A storage groove is formed in a lower side of the quick-assembly plate, and the large screw is disposed within the storage groove. An anti-loosening fastening assembly for preventing loosening of photographic equipment is disposed between the large screw and the quick-assembly plate, and includes a connection hole formed in a head of the large screw, a positioning hole formed in an inner top surface of the storage groove, and a fastener threadedly connectable between the connection hole and the positioning hole. This application solves the problem that a traditional quick-assembly plate becomes loose from photographic equipment in use.
