Solution Overview

Problem

Conventional methods for increasing joint flexibility often require large-scale apparatuses and cause muscle pain or require continuous effort, leading to difficulty in sustained muscle stretching and limited effectiveness.

Innovation Solution

An instrument designed to stimulate the Pacinian corpuscles in the palm using a specific pressing mechanism, reducing muscle pain and promoting muscle stretching to enhance joint range of motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional stretching methods are used, then muscle stretching can be achieved, but muscle pain and suffering occur during the process

Engineering Contradiction:

Improveease of muscle stretchingVSAvoidmuscle pain

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a Pacinian corpuscle pressing instrument as an intermediary tool that indirectly facilitates muscle stretching. By pressing the Pacinian corpuscle in the palm, the instrument mediates the stretching process, reducing direct muscle pain and suffering while still achieving the desired stretching effect.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical stretching actions with a different mechanical mechanism - pressing the Pacinian corpuscle. This substitution transforms the stretching approach from direct muscle manipulation to a indirect neural-mediated process, eliminating the harmful muscle pain while maintaining stretching effectiveness.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional stretching apparatuses are used, then stretching can be performed, but large-scale apparatuses are required making them difficult to use continuously

Engineering Contradiction:

Improveease of continuous stretchingVSAvoidapparatus scale

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of stretching promotion from large-scale apparatuses and concentrates it into a small, portable instrument that presses the Pacinian corpuscle. By taking out only the critical functional element (Pacinian corpuscle stimulation), the instrument becomes compact and easy to use continuously without requiring large-scale equipment.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The instrument is designed to be self-sufficient and portable, allowing users to perform stretching exercises continuously without external apparatus support. The Pacinian corpuscle pressing instrument can be easily carried and used anywhere, enabling continuous stretching practice without dependency on large-scale facility equipment.

Inventive Principle:

Principle #25Self-service

3Duration of action of stationary object

If conventional stretching methods are used, then stretching can be performed, but the flexibility returns to original state unless stretching is performed for a while

Engineering Contradiction:

Improveduration of stretching effectVSAvoidtime required to maintain flexibility

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The patent applies preliminary action by stimulating the Pacinian corpuscle before and during the stretching process. This preliminary neural stimulation prepares the muscle system to maintain stretching effects longer, reducing the time needed to sustain flexibility compared to conventional methods that lack this preparatory neural activation.

Inventive Principle:

Principle #10Preliminary action
