Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing EEG headsets use fixed and bulky structures, then electrode placement is simplified, but comfort and adaptability to varying head sizes and shapes deteriorate

Engineering Contradiction:
Improveelectrode placement simplicityVSAvoidfit for varying head sizes and shapes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The headset is divided into multiple independent strips, each with its own electrodes and fastening mechanism. These strips can be independently adjusted and positioned to accommodate different head sizes and shapes while maintaining simple electrode placement procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The headset incorporates adjustable and removable strips that can be dynamically configured to fit different head geometries. The magnetic fasteners allow for easy adjustment and repositioning, enabling the device to adapt to varying head sizes and shapes without compromising electrode placement simplicity.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If existing EEG headsets use fixed and bulky structures, then structural stability is improved, but comfort and user wearability deteriorate

Engineering Contradiction:
Improvestructural stabilityVSAvoiduser comfort and wearability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The headset is segmented into multiple independent strips rather than a single bulky structure. This segmentation reduces overall bulk while maintaining structural stability through distributed support points and magnetic fastening mechanisms that secure each strip independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Traditional mechanical fastening systems are replaced with magnetic fasteners that provide secure attachment without requiring complex mechanical structures. This substitution reduces the bulk of the headset while maintaining structural stability and improving comfort through easier adjustment and removal.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If existing EEG headsets apply excessive pressure for secure fit, then electrode contact reliability is improved, but user comfort and safety deteriorate

Engineering Contradiction:
Improveelectrode contact reliabilityVSAvoiduser comfort and safety
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Mechanical pressure-based fastening is replaced with magnetic attraction forces. The magnetic fasteners provide secure electrode contact and reliable attachment without requiring excessive pressure, thereby maintaining electrode contact reliability while significantly improving user comfort and safety.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
