Removable Tripod Foot With O-Ring Anti-Loosening Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Removable tripod feet often face difficulties in being securely tightened and resisting loosening due to threaded connections, leading to instability and potential detachment, especially under cyclic loads and vibrations.
Innovation Solution
Incorporation of a resilient element, such as an elastomeric o-ring, at the interface between the foot and the ferrule, which increases friction and maintains contact between the interfacing surfaces to resist loosening, facilitated by an undercut groove and compression mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded connection is used to attach the removable foot to the tripod leg, then the foot can be easily removed and replaced, but the connection becomes difficult to tighten and may loosen under cyclic loads and vibrations
Solution Approach 1:
A resilient element (such as a rubber or elastomeric ring) is introduced as an intermediary component between the foot and the tripod leg. This element increases friction at the interface, preventing the foot from loosening during use while still allowing it to be removed when needed. The resilient element acts as a mediator that maintains the threaded connection's integrity without permanently fixing the foot.
2Reliability
If the threaded connection is tightened sufficiently to prevent loosening, then the foot becomes secure, but the installation becomes difficult and time-consuming
Solution Approach 1:
The resilient element serves as a mediator that increases friction between the foot and tripod leg, allowing the connection to be secure without requiring excessive tightening force. This makes installation easier while maintaining reliability.
Solution Approach 2:
The resilient element changes the friction parameter at the interface between the foot and tripod leg. By increasing friction through the elastic properties of the resilient material, the system achieves secure attachment with less tightening effort, improving ease of operation while maintaining reliability.

AI summary
Installation of a removable tripod foot is facilitated by a cross-axis aperture in the foot and loosening of the threaded connection of the foot and the tripod's leg is resisted by a resilient element engaging interfacing surfaces of the foot and the leg.
