Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional wearable bio-signal measurement devices are designed for specific body-wearing locations (e.g., smart watch for wrist, electrocardiogram patch for heart), then the device can provide specialized measurement functions for that location, but the device becomes difficult to modularize and cannot be easily adapted to other body parts

Engineering Contradiction:

Improveadaptability to different body-wearing locationsVSAvoidmodularization difficulty

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into two main segments: a reusable dock that attaches to various body-wearable products (clothing, bands, belts, underwear, electrode patches) and a detachable sensor unit containing the bio-signal measurement components. This segmentation allows the sensor to be detached and reattached to different docks on various body parts, enabling versatility without requiring complete redesign for each application scenario

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dock is designed with universal attachment capabilities that can be installed on multiple types of body-wearable products including clothing, bands, belts, underwear, and electrode patches. The magnetic attachment mechanism and guide member structure are standardized to work across different product types, allowing a single sensor unit to function with multiple dock configurations on various body locations

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the sensor is permanently fixed to a specific body-wearable product, then the device structure is simplified, but the device loses flexibility and cannot be easily detached or transferred to other products

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The traditional mechanical fastening systems (screws, clips, adhesives) are replaced with a magnetic attachment mechanism. The dock and sensor incorporate magnetic elements that enable automatic alignment and secure attachment through magnetic attraction, while allowing easy detachment by overcoming the magnetic force. This substitution simplifies the user operation while maintaining a relatively simple overall device structure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic field acts as an intermediary force between the dock and sensor, enabling attachment and detachment without direct mechanical contact or complex coupling mechanisms. The guide member serves as a physical intermediary that ensures proper alignment during attachment, working in conjunction with the magnetic force to achieve both ease of operation and structural simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the sensor includes multiple sensing modules (heart rate, ECG, body temperature, galvanic skin response, oxygen saturation, body fat, EMG, motion), then the device can measure various bio-signals comprehensively, but the device size and complexity increase

Engineering Contradiction:

Improvebio-signal measurement capabilityVSAvoidsensor size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Multiple sensing modules for different bio-signal measurements (heart rate, ECG, body temperature, galvanic skin response, oxygen saturation, body fat, EMG, and motion sensing) are merged into a single integrated sensor unit. This consolidation allows comprehensive bio-signal measurement capabilities while minimizing the overall sensor size through shared components, circuits, and processing electronics, rather than using separate devices for each measurement type

Inventive Principle:

Principle #5Merging (Combining)
