Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic rotating massagers are heavy and bulky due to the need for two motors, making them inconvenient to carry and limited to single massage functions.
Innovation Solution
A telescopic rotating negative pressure massager design that uses a single motor to achieve telescopic rotating motion, integrating a suction pump and solenoid valve within a compact housing, allowing for both telescopic rotary and negative pressure massage functions through a snap-in detachable connection between the elastic cylinder and telescopic drive bracket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two motors are used to achieve telescopic rotating motion, then the massage function is improved, but the weight and volume of the massager increase
Solution Approach 1:
The patent combines the telescopic mechanism and rotating mechanism into a single integrated structure. The telescopic drive bracket incorporates both the telescopic motor and rotating motor, allowing one motor to drive both telescopic and rotating motions through a shared transmission system, thereby reducing the total number of motors from two to one while maintaining dual massage functions
Solution Approach 2:
The telescopic drive bracket is designed as a multi-functional component that performs both telescopic motion and rotating motion. The single motor in the telescopic drive bracket can switch between driving the elastic cylinder for telescopic massage and driving the massaging head for rotating massage, making the component universal and eliminating the need for separate motors
2Adaptability or versatility
If two motors are arranged one after another to drive telescopic rotating motion, then the massage function is improved, but the length and volume of the device increase
Solution Approach 1:
The patent employs a nested structure where the rotating mechanism is integrated within the telescopic mechanism. The massaging head with rotating function is nested inside the telescopic drive bracket, and the elastic cylinder is nested within the housing. This nested arrangement allows both telescopic and rotating functions to coexist in a compact space without requiring sequential arrangement of two motors
Solution Approach 2:
The telescopic mechanism and rotating mechanism are merged into a single integrated drive system within the telescopic drive bracket. The transmission components for both telescopic and rotating motions are combined in one structure, reducing the overall length and volume compared to having two separate motors arranged one after another
3Weight of moving object
If a compact design with single motor is used, then the portability is improved, but the massage function may be limited
Solution Approach 1:
The single motor in the telescopic drive bracket is designed to perform multiple functions by switching between driving the elastic cylinder for telescopic massage and driving the massaging head for rotating massage. This universal design ensures that despite using only one motor, the device maintains both telescopic and rotating massage functions
Solution Approach 2:
The patent merges the control of telescopic and rotating functions into a single motor system. The transmission mechanism within the telescopic drive bracket allows one motor to sequentially or alternatively drive both the elastic cylinder and the massaging head, combining multiple massage functions into a single motor-driven system
