Solution Overview

Problem

Conventional spinal thermal massage devices are limited in their ability to effectively massage areas with varying widths, such as the cervical spine, due to fixed acupressure tool spacing that is suitable only for wider intervals like the thoracic or lumbar spine.

Innovation Solution

A massage device with adjustable pressing positions in the width direction, featuring adjustable distance between pressing members using an interval adjusting member, allowing for customizable spacing to accommodate both narrow and wide intervals along the spine.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the distance between acupressure tools in the width direction is fixed, then the device structure is simple, but the device cannot effectively massage parts with narrow intervals such as the cervical spine

Engineering Contradiction:
Improveadaptability to different spinal regionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the distance between pressing members adjustable rather than fixed. The interval adjusting member enables the pressing members to dynamically change their spacing, allowing the device to adapt to different spinal regions (cervical, thoracic, lumbar) with varying width intervals, thus resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by allowing the interval between pressing members to be modified. The interval adjusting member changes the spatial parameter (distance) between pressing members, enabling the same device to effectively massage different spinal regions by adjusting this key parameter, thereby achieving versatility without requiring multiple dedicated devices.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the acupressure tools are positioned for wide intervals, then the device is suitable for thoracic or lumbar spine, but ineffective for narrow intervals like cervical spine

Engineering Contradiction:
Improveapplicability to various body partsVSAvoidmassage effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The dynamics principle is applied by enabling the pressing members to dynamically adjust their spacing through the interval adjusting member. This allows the device to transition between configurations suitable for wide intervals (thoracic/lumbar spine) and narrow intervals (cervical spine), ensuring reliable massage effectiveness across different body parts while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the pressing members are fixed in position, then the device structure is simple, but the thermal massage effect decreases for narrow intervals

Engineering Contradiction:
Improveoperational simplicityVSAvoidthermal massage effectiveness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent resolves the contradiction between operational simplicity and massage effectiveness by implementing a straightforward adjustment mechanism. The interval adjusting member provides an intuitive way to change the spacing between pressing members, maintaining ease of operation while enabling the device to achieve reliable thermal massage effectiveness on narrow intervals like the cervical spine through proper positioning.

Inventive Principle:
Principle #15Dynamics
