Vibration Equipment Rolling Guide Unit to Reduce Noise and Friction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitness beds that vibrate strongly are not suitable for exercising while sleeping or resting, leading to obesity and related health issues among office workers due to lack of exercise opportunities.
Innovation Solution
A multifunctional vibration equipment with a fixed frame, movable frame, first driving member, and rolling guide unit, where the movable frame moves backwards and forwards, and the rolling guide unit reduces friction and wear by using rollers in slots, allowing for adjustable vibration frequency and reduced noise, enabling exercise during sleep or rest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bed board vibrates strongly and violently to provide exercise effect, then the exercise effectiveness is improved, but the noise level increases and user comfort deteriorates
Solution Approach 1:
The patent introduces a rolling guide unit with rollers as an intermediary mechanism between the driving mechanism and the bed board. The rollers convert sliding friction into rolling friction, enabling smooth vibration movement with significantly reduced noise and energy loss, thus allowing strong vibration exercise effectiveness without the harmful noise typically associated with such movements
Solution Approach 2:
The patent replaces the traditional direct vibration mechanism with a rolling-based mechanical system. By using rollers in guiding slots, the system substitutes direct mechanical contact and sliding friction with rolling motion, achieving the same exercise vibration effect while dramatically reducing noise levels and mechanical wear
2Productivity
If the bed board vibrates strongly and violently to provide exercise effect, then the exercise effectiveness is improved, but the user comfort deteriorates
Solution Approach 1:
The rolling guide unit acts as a mediator that smooths out the vibration transmission. The rollers provide a cushioning effect through rolling motion, reducing the violent and jarring movements while maintaining the exercise effectiveness, thus improving user comfort during the vibration exercise
Solution Approach 2:
The patent incorporates rolling elements that inherently provide cushioning before the vibration force is fully transmitted to the user. The rolling mechanism absorbs and dampens shock peaks, preparing a smoother vibration profile that maintains exercise benefits while protecting user comfort
3Device complexity
If traditional sliding connection is used between fixed frame and movable frame, then the structure is simple, but the friction and wear are high
Solution Approach 1:
The patent employs cylindrical rollers instead of flat sliding surfaces. The curved rolling surfaces convert sliding friction into rolling friction, dramatically reducing wear and friction while maintaining structural simplicity. The rollers fit into guiding slots, providing a reliable low-friction connection between the fixed and movable frames
4Productivity
If strong vibration is applied to achieve exercise effect, then the exercise benefit is improved, but the equipment wear increases
Solution Approach 1:
The patent substitutes sliding mechanical contact with rolling contact through the rolling guide unit. This substitution dramatically reduces mechanical wear on the equipment components while maintaining the strong vibration necessary for exercise benefits, thereby extending equipment lifespan
