Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid damping devices lack the ability to adjust resistance, requiring users to replace liquids of varying viscosity, which is labor-intensive and ineffective in adjusting resistance levels.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If liquid replacement method is used to adjust resistance, then resistance adjustment is achieved, but labor consumption increases and adjustment effectiveness is poor
Solution Approach 1:
The patent changes the parameter of liquid level height in the damping device. By adjusting the liquid level height through the adjusting disc with through holes, the resistance experienced by the rotating disc is modified without replacing the liquid. This allows continuous resistance adjustment while maintaining the same liquid medium, resolving the contradiction between adaptability and ease of operation.
2Adaptability or versatility
If fixed resistance design is used, then device structure is simple, but user needs cannot be accommodated
Solution Approach 1:
The patent segments the cavity into multiple regions using an adjusting disc with through holes. This segmentation allows different portions of the liquid to be exposed or hidden based on the disc's rotational position, enabling resistance adjustment without complex mechanical structures. The simple segmentation approach adds adaptability while minimizing structural complexity.
3Adaptability or versatility
If liquid viscosity replacement is used for resistance adjustment, then resistance control is achieved, but adjustment range is limited and labor intensive
Solution Approach 1:
The patent enables self-service resistance adjustment by allowing users to rotate the adjusting disc to change the liquid level height and thus the resistance. This eliminates the need for external intervention or time-consuming liquid replacement processes, as the system provides its own adjustment mechanism that is both rapid and user-operable.
