Tripod Leg One-Button Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tripod legs require multiple independent lock/unlock switches for each telescopic section, making height adjustment complicated and slow.
Innovation Solution
A one-button operation support leg with an interlocking mechanism that synchronizes the locking and unlocking of multiple sections through a single active locking mechanism, using a combination of active and passive locking mechanisms and an interlocking mechanism to ensure simultaneous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent lock/unlock switches are used for each telescopic section, then each section can be locked securely, but the operation becomes complicated and slow
Solution Approach 1:
The patent combines multiple independent locking mechanisms into a unified system where a single operating member controls both the active locking mechanism (between first and second section brackets) and the passive locking mechanism (between second and third section brackets) through an interlocking mechanism. This merging allows simultaneous locking/unlocking of multiple sections, reducing operational complexity while maintaining secure locking through the coordinated action of both mechanisms
2Reliability
If multiple independent lock/unlock switches are used for each telescopic section, then each section can be locked securely, but the adjustment speed becomes slow
Solution Approach 1:
The patent merges the operation of multiple locking mechanisms into a single action through the interlocking mechanism. When the operating member is actuated, it simultaneously triggers both the active locking mechanism and the passive locking mechanism, enabling rapid adjustment of the tripod leg height by locking multiple sections at once, thereby significantly increasing adjustment speed while preserving reliable locking
3Ease of operation
If an interlocking mechanism is added to synchronize locking mechanisms, then operation is simplified to one button, but device complexity increases
Solution Approach 1:
The patent introduces an interlocking mechanism as an intermediary component that connects the active locking mechanism and the passive locking mechanism. This intermediary synchronizes the operation of both mechanisms through a single operating member, simplifying user interaction to one-button operation while the internal complexity is encapsulated within the interlocking mechanism itself, managing the trade-off between operational simplicity and mechanical complexity

AI summary
One-button operation type support leg and support foot frame includes a first bracket, a second bracket and a third bracket. The second bracket may slide relative to the first bracket, and the third bracket may slide relative to the second bracket in the length extension direction. An active locking mechanism locks or unlocks the first bracket and the second bracket being disposed between the first bracket and the second bracket, and a drive locking mechanism locks or unlocks the second bracket and the third bracket being disposed between the second bracket and the third bracket. An interlocking mechanism may be disposed between the active locking mechanism and the drive locking mechanism. The active locking mechanism drives the driven locking mechanism to move through the interlocking mechanism, so the drive locking mechanism and the active locking mechanism are in a locked state or in an unlocked state at the same time.
