Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional quick connection structure is used, then the camera can be connected to the tripod, but the structure is complex and inconvenient to assemble or disassemble

Engineering Contradiction:
ImproveConvenience of assembly and disassemblyVSAvoidConstruction complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking mechanism is divided into separate functional components: a locking component with locking portions, reset components for automatic resetting, and an unlocking portion. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process while maintaining functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reset components automatically reset the locking component after unlocking, eliminating the need for manual intervention. When the unlocking portion is actuated, the locking component moves to unlock the connection, and the reset components automatically return the locking component to its original position, enabling single-handed operation.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual locking mechanisms are used, then connection security is achieved, but continuous manual force application is required

Engineering Contradiction:
ImproveConnection securityVSAvoidManual force requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The reset components automatically reset the locking component after unlocking, eliminating the need for continuous manual force application. The system self-regulates the locking state, maintaining connection security while reducing operational effort.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking component moves periodically between locked and unlocked states through the interaction of the reset components and unlocking portion. This periodic action allows the mechanism to maintain security while enabling easy transitions between states without continuous manual intervention.

Inventive Principle:
Principle #19Periodic action

AI summary

A quick connection structure includes a first component, a second component, a locking component and a first reset component. The second component includes a mounting portion defining a mounting groove, a first locking portion, a second locking portion and an unlocking portion. The locking component is movably connected to the mounting portion. The first reset component is arranged between the locking component and the mounting portion. The locking component drives the first locking portion to a locking position during the movement thereof to a first position and enables the first locking portion to an unlocking position when moving to a second position. The first locking portion at the locking position locks the first component, and at the unlocking position unlocks the first component. The second locking portion locks the locking component at the second position, and the unlocking portion drives the second locking portion to unlock the locking component.
