Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional loudspeakers are used, then they can provide audio output, but they cannot be connected in parallel and lack flexibility for various applications

Engineering Contradiction:
Improveconnectability and application flexibilityVSAvoidsystem configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The loudspeaker system is divided into multiple independent electret loudspeaker units, each capable of being connected to others through connection ports. This segmentation allows flexible parallel connections while maintaining individual unit functionality, resolving the contradiction between adaptability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each electret loudspeaker unit is designed with universal connection ports that enable parallel connection to other units and compatibility with various audio sources. This multi-functionality allows the same basic unit to serve different applications and configurations without increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple electret loudspeaker units are connected in parallel, then adaptability and application range are improved, but connection and circuit structure complexity increases

Engineering Contradiction:
Improveparallel connection capabilityVSAvoidcircuit board and connection structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple electret loudspeaker units are merged into a parallel connection system where each unit maintains its independence but functions collectively. The connection ports and circuit boards are designed to facilitate this merging without requiring complex wiring or control structures, thus enabling parallel connection capability while managing complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of moving object

If electret loudspeaker units are made small and thin, then they offer advantages in size and efficiency, but they lack the presence and impact of conventional loudspeakers

Engineering Contradiction:
Improveloudspeaker unit sizeVSAvoidapplication scope in interior design and decoration
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The design transitions from considering only the individual unit dimensions to utilizing the two-dimensional arrangement of multiple small units. By connecting multiple compact electret loudspeaker units in parallel, the system achieves both the size advantages of small units and the visual impact/adaptability of larger configurations through spatial arrangement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
