Solution Overview

Problem

The existing assembling and disassembling mechanisms for shooting devices, such as camcorders and cameras, are complex and cannot be quickly assembled or disassembled in one step, often requiring additional anti-slewing mechanisms to prevent loosening, complicating the process.

Innovation Solution

A quick release and assembly connecting member comprising a connecting cover, a mounting seat, and a fixing mechanism with a clamping and locking sleeve and a toggle wrench that switches between locking and unlocking positions to facilitate easy assembly and disassembly, featuring a C-shaped clamping sleeve and anti-off locking head for secure engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If close nipples are used as assembling and disassembling mechanisms, then the shooting device can be fixed to other devices, but the assembly and disassembly process becomes complex and cannot be quickly completed

Engineering Contradiction:
Improveassembly and disassembly operationVSAvoidassembling and disassembling mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connecting member is divided into distinct components: a connecting cover with an inserting portion and a mounting seat with a clamping mechanism. This segmentation allows the locking function to be achieved through a simpler clamping action rather than a complex threaded engagement, enabling quick assembly and disassembly while reducing overall structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a traditional screw-based closing mechanism that requires rotational movement and threading, the invention inverts the approach by using a clamping mechanism that applies direct radial force through the toggle wrench. This inversion transforms the assembly process from a multi-step rotational closing to a single-step clamping action, dramatically simplifying the operation.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If an extra anti slewing mechanism is added to prevent close nipple loosening, then the anti-slewing function is achieved, but the base of quick release becomes more complex

Engineering Contradiction:
Improveanti-loosening functionVSAvoidquick release base structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The anti-loosening function is merged into the clamping mechanism itself. The toggle wrench, when activated, not only performs the locking function but also inherently prevents loosening through its mechanical geometry. The C-shaped clamping sleeve with its elastic deformation provides both the locking force and the anti-slewing capability in a single integrated mechanism, eliminating the need for separate anti-loosening components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamping mechanism is designed to be self-locking through the toggle wrench mechanism. Once the toggle wrench is activated to clamp the inserting portion, the mechanical advantage of the toggle mechanism automatically maintains the clamping force without requiring additional anti-slewing components. The elastic C-shaped clamping sleeve provides continuous radial pressure that prevents loosening, making the system self-sufficient for preventing sleeve loosening.

Inventive Principle:
Principle #25Self-service

3Reliability

If traditional screw-based methods are used for assembly, then the connection is secure, but the assembly and disassembly process is time-consuming and complex

Engineering Contradiction:
Improveconnection securityVSAvoidassembly and disassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The clamping mechanism transitions from a static threaded connection to a dynamic toggle-based system. The toggle wrench can be quickly activated to engage the clamping sleeve, and just as quickly deactivated to release it. This dynamic mechanism allows the connection to be securely established and released in seconds, dramatically improving assembly and disassembly speed while maintaining connection security through the elastic clamping force.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the fundamental parameter of connection establishment from rotational movement (screwing) to linear radial movement (clamping). By changing the motion parameter from rotational to radial clamping, the assembly process becomes much faster while the elastic deformation of the C-shaped clamping sleeve ensures secure connection. The toggle mechanism amplifies the applied force to achieve reliable clamping with minimal user effort.

Inventive Principle:
Principle #35Parameter changes

AI summary

A quick release and assembly connecting member and a shooting device are provided. The quick release and assembly connecting member includes a connecting cover, a mounting seat, and a fixing mechanism. The connecting cover includes an inserting portion. The mounting seat includes a mounting and locking mechanism. The fixing mechanism is arranged on the connecting cover and/or the mounting seat, and configured for mounting and fixing the quick release and assembly connecting member with a device. The mounting and locking mechanism includes a clamping and locking sleeve and a locking member. The clamping and locking sleeve is configured to enclose a mounting space for mounting the inserting portion, and the locking member is capable of switching between a first position and a second position, so that when the inserting portion is mounted in the mounting space, the locking member is capable of locking or unlocking the inserting portion.
