Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If existing apparatuses for interoceptive tactile stimulation are used, then tactile stimulation can be provided, but automatic regulation based on skin characteristics is not achieved and specialized personnel are required

Engineering Contradiction:
Improveautomatic regulation of tactile stimulationVSAvoidrequirement for specialized personnel
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The apparatus automatically detects skin characteristics (such as skin thickness and mechanical properties) and adjusts stimulation parameters (force, velocity, frequency) without requiring specialized personnel. The system serves itself by using sensors to monitor skin properties and control algorithms to maintain optimal stimulation parameters throughout the treatment session.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates sensors that continuously monitor skin characteristics and provide feedback to the control unit. Based on this feedback, the apparatus dynamically adjusts stimulation parameters to maintain optimal conditions for activating C-Tactile afferents, ensuring automatic regulation adapts to individual user variations.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If existing apparatuses are used, then tactile stimulation is provided, but portability for use in different locations and on multiple body parts is limited

Engineering Contradiction:
Improveportability and multi-site use capabilityVSAvoidapparatus portability
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The apparatus is designed as a portable, handheld device that can be easily moved to different body parts. The stimulation mechanism is segmented into modular components that allow the device to be applied to various locations on the body while maintaining consistent stimulation quality across different sites.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If manual regulation of stimulation parameters is used, then specialized control is achieved, but consistency of stimulation parameters across varying skin conditions is not maintained

Engineering Contradiction:
Improveconsistency of stimulation parametersVSAvoidparameter regulation mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The apparatus performs preliminary detection of skin characteristics before initiating stimulation. By measuring skin thickness, mechanical properties, and other relevant parameters in advance, the system pre-configures optimal stimulation parameters specific to each user's skin conditions, ensuring consistent and precise stimulation throughout the treatment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes stimulation parameters (force, velocity, frequency) based on detected skin characteristics. The control unit adjusts these parameters in real-time to maintain optimal activation of C-Tactile afferents across varying skin conditions, achieving precision through automated parameter adaptation rather than manual regulation.

Inventive Principle:
Principle #35Parameter changes
