Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massaging structures are not expandable and are heavy, making them difficult to use on different parts of the body and inconvenient to carry.
Innovation Solution
A mat transmission structure with a first body, pivotally mounted operation units, and a power unit that allows for expansion and placement on any plane, providing a massaging effect by rotating operation units with eccentric construction for height variation and angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional massaging rollers with fixed mounting are used, then the massaging structure provides stable massaging function, but the structure cannot be expanded to massage other parts of the body
Solution Approach 1:
The massaging structure is divided into independent massaging units that can be selectively activated. Each massaging unit operates independently through its own driving member, allowing the system to be expanded to different body parts by activating additional units without redesigning the entire structure.
Solution Approach 2:
The massaging structure is designed with multiple massaging units that can be applied to different parts of the body. The same basic structure serves multiple functions by positioning different massaging units on various body areas, achieving versatility without increasing overall structural complexity.
2Ease of operation
If massaging rollers and motors are mounted on a base with swinging arm, then the massaging function is achieved, but the structure becomes heavy and difficult to carry
Solution Approach 1:
The heavy base and swinging arm structure is removed from the design. The massaging units are mounted directly on a simplified support structure, extracting the unnecessary weight-bearing components while maintaining the massaging function through direct mounting of the lighter massaging units.
Solution Approach 2:
Instead of mounting the massaging units on a heavy base and then moving the entire assembly, the design inverts the approach by using lightweight individual massaging units that can be independently positioned and activated, eliminating the need for a heavy supporting base.
3Ease of operation
If multiple motors are mounted in the swinging arm to drive massaging rollers, then the massaging function is achieved, but the weight of the swinging arm increases
Solution Approach 1:
The swinging arm structure is completely removed from the design. The motors are mounted directly on the simplified support structure, extracting the unnecessary swinging arm component that added weight without providing functional benefit in the new design configuration.
Solution Approach 2:
Instead of placing motors in a swinging arm that then drives the massaging rollers, the design inverts the arrangement by mounting the motors directly on the support structure with direct drive to the massaging units, eliminating the intermediate swinging arm and its associated weight.
