Solution Overview

Problem

Existing personal massagers lack interchangeable massager heads that can be vibrated or heated, and they do not have an auxiliary grip for improved handling and compactness.

Innovation Solution

A personal massager system with an elongated handle, a controller module that can be mounted to the handle and includes a vibration motor and heating capabilities, and interchangeable massager heads that can be attached to the controller module or a massager mount. The system also includes an auxiliary grip that can be attached to the handle or the controller module for enhanced grip and compactness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a personal massager uses a simple elongated handle without additional components, then the device complexity is reduced and manufacturing cost decreases, but the massager lacks interchangeable heads with vibration or heating capabilities and cannot provide versatile massage options

Engineering Contradiction:

Improvemassage therapy optionsVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The massager is divided into separate functional modules: a handle, a controller module, and interchangeable massager heads. Each module can be independently manufactured and assembled, allowing versatility through different head combinations while keeping individual component complexity manageable

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The controller module and handle are designed as universal components that can work with multiple types of massager heads. The standardized interface allows a single controller to support vibration, heating, and different massage head types, achieving multi-functionality without proportionally increasing overall device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the handle is designed without an auxiliary grip, then the device structure is simpler and easier to manufacture, but the user experiences reduced grip comfort and handling difficulty when massaging hard-to-reach areas

Engineering Contradiction:

Improvegrip comfortVSAvoidhandle structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The auxiliary grip is designed as a separate, detachable component rather than an integrated part of the handle. This allows the grip to be added only when needed for specific massage positions, improving ease of operation without permanently increasing the base device complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The auxiliary grip can be selectively attached or removed from the handle based on the user's needs for different massage positions. This dynamic configuration allows the device to adapt its ergonomics without being permanently more complex

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If interchangeable massager heads with vibration motors and heating elements are integrated into the handle, then versatile massage therapy options are provided, but the device complexity and manufacturing cost increase significantly

Engineering Contradiction:

Improvemassage therapy optionsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Complex functions like vibration motors and heating elements are isolated in separate, interchangeable massager heads rather than being integrated into the main handle. This allows each head type to be manufactured independently using optimized processes for that specific function, reducing overall manufacturing complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The massager heads are designed with standardized interfaces and mounting mechanisms that can be replicated across different head types. This modular copying approach allows versatile functionality while maintaining consistent, manageable manufacturing processes for each module

Inventive Principle:

Principle #26Copying

AI summary

A personal massager assembly for facilitating a user to massage the user's own shoulders includes a handle which is elongated between a first end and a second end and comprises a shoulder portion which is shaped and configured to extend around the shoulder of the user. A controller module with a vibration motor is selectively mountable to the second end of the handle, and a massager head is selectively mountable to the controller module such that the vibration motor is operable to vibrate the massager head. In some embodiments, multiple massager heads may be interchangeably mountable to the controller module or a massager mount that does not have another vibration motor. A heater massager may be configured to mount to the controller module and be caused to heat by the controller module. An auxiliary grip may attach to the handle or interchangeably to any of the massager heads.
