Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an existing earphone is worn, then the earphone can be used to provide auditory experience, but the portion that hangs on the human ear has poor elasticity which adversely affects wear experience

Engineering Contradiction:
Improvewear experienceVSAvoidelasticity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The ear hook is divided into multiple sections: a first section with a first curvature radius, a second section with a second curvature radius, and a third section with a third curvature radius. Each section has different curvature characteristics to provide localized elasticity and adaptability to different parts of the ear, resolving the contradiction between overall structural integrity and localized elastic adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ear hook incorporates multiple curved sections with different curvature radii that can dynamically adapt to the ear's shape. The varying curvatures allow the structure to flex and conform to different ear geometries while maintaining its functional integrity, thereby improving both reliability and adaptability.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the ear hook structure is simplified for easier manufacture, then manufacturing cost decreases, but the elasticity and fit to different ear shapes deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidelasticity
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

By segmenting the ear hook into distinct curved sections, each with specific curvature radii, the design achieves complex elastic behavior through relatively simple geometric elements. This segmented approach allows for easier manufacturing compared to creating a single complex curved structure, while still providing the needed adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design varies the curvature radius parameter across different sections of the ear hook. This parameter change allows each section to have optimized elastic properties for its specific location, achieving high adaptability through controlled variation of a single geometric parameter rather than complex multi-parameter design.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If a rigid structure is used for the ear hook, then structural stability improves, but comfort and adaptability to different ear shapes deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidelasticity
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The ear hook is segmented into multiple curved sections where each section maintains structural integrity through its defined curvature while the combination of sections provides overall flexibility. This segmentation allows the structure to remain stable in each local region while adapting globally to different ear shapes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ear hook utilizes multiple curved sections with different curvature radii instead of straight or uniform curved lines. These varying curvatures provide inherent flexibility and elastic deformation capability while maintaining structural stability, allowing the rigid-looking structure to adapt comfortably to different ear geometries.

Inventive Principle:
Principle #14Spheroidality (Curvature)
