Solution Overview

Problem

Existing therapeutic massage devices face complications in changing components, and the vibrations during use cause them to become loose, necessitating a system that securely attaches multiple treatment elements to a reciprocal massage or therapeutic treatment device.

Innovation Solution

An adapter assembly with a main body portion featuring top and bottom attachment members, arms, and detents or balls for secure attachment of treatment members to a reciprocal massage or therapeutic treatment device, ensuring stable connection and easy interchangeability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple attachment mechanism is used, then the device complexity is reduced and ease of operation is improved, but the treatment members may become loose during use due to vibrations

Engineering Contradiction:
Improveease of changing componentsVSAvoidstability of attachment during use
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The attachment mechanism uses spring-loaded balls that dynamically adapt to the treatment member surface. The balls are biased outward by springs to engage with detents on the treatment member, providing automatic adjustment and maintaining secure engagement despite vibrations or position changes during use.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The attachment mechanism is divided into multiple independent ball-detent pairs distributed around the circumference. Each ball-detent pair independently secures the treatment member, so that if one engagement point experiences stress or misalignment, other points maintain the secure connection, preventing the treatment member from becoming loose.

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple treatment members are attached simultaneously, then the productivity and treatment effectiveness are improved, but the device complexity and difficulty of attachment increase

Engineering Contradiction:
Improvenumber of treatment members attachedVSAvoidcomplexity of attachment system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The attachment mechanism uses identical ball-detent pairs at multiple locations around the circumference, all functioning according to the same principle. This universal design allows the same simple mechanism to secure multiple treatment members simultaneously without requiring different attachment systems for each position, thus increasing productivity without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple treatment members are attached to a single hub structure that integrates all attachment points. The hub combines multiple ball-detent mechanisms into one unified component, allowing simultaneous attachment of several treatment members while maintaining a compact, organized structure rather than having separate attachment systems for each member.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a secure attachment mechanism with multiple engagement points is used, then the reliability and stability are improved, but the device complexity increases

Engineering Contradiction:
Improvesecurity of attachmentVSAvoidnumber of attachment components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring-loaded balls provide dynamic engagement where the springs automatically adjust the engagement force. This dynamic mechanism maintains reliable attachment without requiring complex adjustment mechanisms, as the springs self-regulate to provide consistent securing force across multiple engagement points.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The attachment mechanism is self-securing through the spring-loaded balls that automatically engage with detents on the treatment member. The springs provide continuous outward bias to maintain engagement, and the detents provide automatic positioning, eliminating the need for additional locking mechanisms or complex assembly procedures despite having multiple engagement points.

Inventive Principle:
Principle #25Self-service
