Solution Overview

Problem

Existing massage devices face issues with the continuous and stable operation of their heating modules due to poor contact between the brush and conductive copper rings, leading to inconsistent thermotherapy delivery.

Innovation Solution

The massage device incorporates a heating module fixed relative to the base, eliminating the need for a brush and ring-shaped conductive plate, and features a heating chamber formed by the enclosure and massage head to ensure consistent heat distribution and prevent heat loss, allowing the heating module to operate continuously and stably.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a brush and ring-shaped conductive plate are used to power the heating module, then the heating module can be powered, but the contact is poor leading to unstable operation

Engineering Contradiction:

Improveheating module operation stabilityVSAvoidheating module structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the brush and ring-shaped conductive plate from the heating module structure, eliminating the components that caused poor contact and unstable operation. The heating module is directly integrated with the base, extracting the problematic intermediate connection elements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The heating module is merged with the base structure, creating an integrated assembly where the heating module is fixed to the base. This merging eliminates the need for separate conductive components and ensures stable electrical connection.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If the heating module is not enclosed, then the structure is simple, but heat is lost leading to inconsistent thermotherapy

Engineering Contradiction:

Improvethermotherapy consistencyVSAvoidheating chamber structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the internal structure by introducing an enclosure that divides the space into a heating chamber and other areas. This segmentation allows the heating module to be isolated and enclosed, preventing heat loss while maintaining structural organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The enclosure acts as a shell structure that surrounds the heating module, creating a contained heating chamber. This shell structure traps and directs heat toward the massage head while preventing heat loss to the surrounding environment.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of operation

If the massage head rotates freely, then the massage function works well, but the heating module cannot maintain stable contact

Engineering Contradiction:

Improvemassage head rotationVSAvoidheating module contact

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the device into a stationary base containing the heating module and a rotating massage head. This segmentation allows the heating module to remain fixed for stable operation while the massage head rotates independently for massage function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent separates the heating module in the horizontal plane (fixed to base) from the rotating massage head, using vertical positioning and enclosure structure to maintain stable heating contact while allowing rotational movement at the massage head level.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A massage device includes a base, a driving module, a massage head, and a heating module. The massage head is connected to the driving module, a side of the massage head away from the base is provided with a massage protrusion, and a first cavity is formed on a side of the massage head facing the base. The heating module is fixed relative to the base and located between the base and the massage head, wherein the heating module is configured to generate heat when energized to heat the air in the first cavity, so as to provide thermotherapy from the massage device to a part of a user's body.
