Massaging Device Tilting Shaft Multi-Area Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massaging devices have limited massage effectiveness as they are designed to stimulate only one area of the body simultaneously and have a short service life due to their movement mechanisms.
Innovation Solution
A massaging device with a driving assembly that includes a tilting shaft and a rotating element, allowing the device to swing and massage multiple areas of the body, featuring a flexible structure and lubrication grooves for smooth operation, thereby increasing the service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the massaging device uses a fixed vibration mechanism, then the structure is simple, but it can only massage one area of the body at a time
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed vibration mechanism into a dynamic swinging mechanism. The tilting shaft enables the massaging head to swing between multiple angles, allowing the device to massage different areas of the body sequentially. This dynamic movement resolves the contradiction by providing multi-area coverage while maintaining a relatively simple mechanical structure through controlled motion rather than multiple fixed components.
Solution Approach 2:
The patent segments the massaging function by dividing the single massaging head into multiple functional positions through the swinging mechanism. The tilting shaft creates distinct angular positions (first angle and second angle) that correspond to different massage areas, effectively segmenting the massage coverage without requiring multiple separate devices or complex multi-headed structures.
2Reliability
If the massaging device uses a rigid movement mechanism, then the structure is stable, but the service life is short due to wear and tear
Solution Approach 1:
The patent employs flexible design principles by using a flexible connection between the tilting shaft and the massaging head. This flexible connection allows for smooth angular transitions while reducing mechanical stress and wear on rigid components. The flexibility absorbs operational stresses that would otherwise lead to wear and tear, thereby extending service life without requiring overly complex reinforcement structures.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating damping or cushioning elements in the movement mechanism that anticipate and mitigate wear before it occurs. These elements protect critical components from excessive stress during the swinging motion, preventing premature failure and extending the overall service life of the device.
3Adaptability or versatility
If the tilting shaft length is increased to expand massage range, then more areas can be covered, but the structural stability decreases
Solution Approach 1:
The patent resolves this contradiction by utilizing angular dimension rather than purely linear extension. Instead of simply lengthening the tilting shaft which would compromise stability, the invention creates multiple angular positions (first angle and second angle) that expand the massage range in a different dimensional space. This allows comprehensive body coverage while maintaining a compact, stable structural base.
