Solution Overview

Problem

Existing handheld massagers require manual reciprocating motion for massage, leading to inconvenience in use.

Innovation Solution

A peristaltic massager with a reciprocating driving mechanism that drives a peristaltic sliding member to achieve linear reciprocating motion of massage heads, facilitated by a peristaltic mechanism with intersecting spiral tracks and a linkage member to ensure smooth transitions between tracks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual reciprocating motion is used to operate the massager, then the structure can be simple, but the ease of operation deteriorates due to continuous reciprocating motion requirement

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The massager performs the reciprocating motion automatically through the peristaltic mechanism driven by rotation, without requiring the user to manually reciprocate the device. The system serves itself by converting rotational input into automatic back-and-forth massage motion.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual reciprocating mechanical operation is replaced by a rotational driving mechanism coupled with a peristaltic sliding mechanism. The rotation-driven peristaltic structure substitutes the need for manual back-and-forth motion, transforming the operating mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If the peristaltic sliding member moves quickly along the spiral tracks, then productivity is improved, but the comfort of massage deteriorates due to high reciprocating speed

Engineering Contradiction:

ImproveproductivityVSAvoidcomfort of massage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The speed parameter of the peristaltic sliding member is optimized to achieve a balance between productivity and comfort. By adjusting the reciprocating speed to an appropriate range, the system maintains efficient massage coverage while ensuring comfortable contact pressure and rhythm for the user.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the fitting portion switches between first spiral track and second spiral track, then adaptability is improved, but device complexity worsens due to transition mechanism

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fitting portion is designed to dynamically switch between the first spiral track and the second spiral track based on the rotational position. This dynamic track switching enables the massager to adapt its motion path while the rotatable linkage provides the mechanical flexibility needed for smooth transitions between tracks.

Inventive Principle:

Principle #15Dynamics

AI summary

A peristaltic massager, where a reciprocating driving mechanism drives a peristaltic sliding member to reciprocate to realize linear motion of massage heads on the peristaltic sliding member along a length direction of a gripping body, and the motion drives the massage heads to move to achieve the effect of automatic massage, making the use of the peristaltic massager more convenient.
