Tripod Leg Lock Sealing Structure for Dirty Water Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tripods face issues with waterproofing and durability in hostile environments due to the abrasion and corrosion of rubber components in their locking mechanisms, leading to poor sealing and reduced functionality in dirty or salty water conditions.
Innovation Solution
The design incorporates a locking mechanism with a collet ramp and O-rings to create a waterproof seal between the leg sections, using a flexible rubberized knob tread and O-rings to maintain a watertight seal while minimizing drag, and includes a slit in the leg yoke for air exchange to prevent backpressure, along with a circular ring or v-shaped ring for enhanced sealing and contamination prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rubber components are used in the locking mechanism for sealing, then waterproofing is improved, but durability deteriorates due to abrasion and corrosion in hostile environments
Solution Approach 1:
The patent introduces a sealed locking mechanism that acts as an intermediary barrier between the external hostile environment and the internal locking components. The seal prevents direct contact between corrosive elements (saltwater, dirt) and the rubber components, thereby maintaining both waterproofing and durability simultaneously
2Ease of operation
If a locking mechanism is designed for efficient operation, then ease of operation is improved, but sealing performance deteriorates in dirty environments due to fouling
Solution Approach 1:
The locking mechanism is segmented into distinct functional zones: an external sealed portion that interfaces with the environment and an internal operational portion that remains protected. This segmentation allows the external seal to handle contamination while the internal mechanism maintains efficient operation, resolving the contradiction between ease of operation and sealing performance
