Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage sticks with single vibration function and movement mode fail to provide a fully satisfying experience for users, lacking multi-directional touch sensation.
Innovation Solution
A telescopic machine core design that incorporates a shell, sliding wheel disc, bracket, motor, reciprocating screw rod, spiral grooves, driving block, eccentric wheels, and massage beads, allowing the sliding wheel disc to move up and down and the vibrating head to swing, enhancing multi-directional touch sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vibration function is used in the massage stick, then the structure is simple, but the massage experience and user satisfaction are insufficient
Solution Approach 1:
The patent combines multiple massage functions (vibration, sliding, swinging) into a single machine core structure. The sliding wheel disc assembly integrates both sliding motion (for pressing massage) and swinging motion (for rolling massage), while the vibration module provides additional vibration function. This merging of multiple functions into one unified structure increases adaptability without proportionally increasing device complexity.
Solution Approach 2:
The machine core is designed as a multi-functional unit that can perform vibration, sliding, and swinging operations. The sliding wheel disc can both slide along the rotating shaft for pressing massage and swing left-right for rolling massage, making the same component serve multiple massage purposes. This multi-functionality directly addresses the need for varied massage experiences while controlling structural complexity.
2Adaptability or versatility
If only vibration motion is provided, then the movement mode is simple, but the multi-directional touch sensation cannot be achieved
Solution Approach 1:
The patent introduces dynamic motion capabilities to the massage stick through the sliding wheel disc assembly. The wheel disc can slide along the rotating shaft to create pressing motion, and simultaneously swing left-right to create rolling motion. This dynamic addition of sliding and swinging capabilities transforms the static vibration-only motion into multi-directional dynamic massage movements, achieving varied touch sensations.
Solution Approach 2:
The patent adds spatial dimensions to the massage motion. The sliding wheel disc moves not only in the vertical vibration direction but also slides along the shaft (adding one dimension) and swings left-right (adding another dimension). This multi-dimensional movement capability enables the massage beads to contact the user's body from multiple angles, creating rich multi-directional touch sensations.
