Waterproofing Ring for Rotary Knob Manipulation Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manipulation devices with waterproof functions are complex, generate excessive rotational resistance, and fail to effectively handle pivoting operations, making them difficult to operate and bulky.
Innovation Solution
A multifunction manipulation device featuring a rotary knob, button, and a waterproofing ring that rotates with the rotary knob, providing a simple and inexpensive configuration for waterproofing while allowing easy operation and reduced rotational resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an anti-drip member is installed to waterproof the gap between the rotary dial and push button knob, then waterproofing function is improved, but the structure becomes complicated and rotational resistance increases
Solution Approach 1:
The patent merges the waterproofing function with the rotary dial structure by integrating the anti-drip member as a groove on the rotary dial itself rather than as a separate component. This eliminates the need for additional anti-drip members and simplifies the overall structure while maintaining waterproofing effectiveness.
Solution Approach 2:
The rotary dial is designed to serve multiple functions: it acts as both the rotary operation interface and the waterproofing structure through its integrated groove design. This multi-functionality reduces the number of separate components needed and simplifies the device structure.
2Reliability
If an anti-drip member is installed to waterproof the gap between the rotary dial and push button knob, then waterproofing function is improved, but rotational resistance increases causing parts to wear out
Solution Approach 1:
The waterproofing structure is merged into the rotary dial itself through an integrated groove, eliminating the need for separate anti-drip members that would create friction. This reduces rotational resistance and prevents wear on moving parts while maintaining effective waterproofing.
3Reliability
If a bellows mechanism is provided to waterproof the joystick, then waterproofing function is improved, but the device size increases
Solution Approach 1:
The waterproofing function is merged into the existing manipulation device structure through integrated grooves on the rotary dial and button, eliminating the need for separate bellows mechanisms. This maintains compact device dimensions while achieving effective waterproofing.
Solution Approach 2:
The patent uses thin groove structures formed on the rotary dial and button surfaces to provide waterproofing without adding significant volume. These thin-film-like grooves effectively seal gaps without requiring bulky bellows mechanisms.
