Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple sound output modules are used to achieve multi-directional sound coverage, then sound output range is improved, but device complexity increases

Engineering Contradiction:

Improvesound output rangeVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sound output module is divided into multiple sound output units, each with its own sound output surface. These units are arranged in different orientations (e.g., upward, downward, sideways) to achieve multi-directional sound coverage without requiring multiple separate modules, thus reducing structural complexity while expanding sound output range.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces spatial dimensionality by orienting sound output surfaces in multiple directions (upward, downward, sideways) rather than a single direction. This dimensional approach allows one sound output module to achieve the functionality of multiple modules, resolving the contradiction between sound output range and device complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple sound output modules are used to achieve multi-directional sound coverage, then sound output range is improved, but volume and weight increase

Engineering Contradiction:

Improvesound output rangeVSAvoidapparatus volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Multiple sound output units with different orientations are merged into a single integrated sound output module. This consolidation achieves multi-directional sound coverage while minimizing the overall volume and weight compared to using separate modules, as the units share common structural elements and housing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The sound output module is designed as a multi-functional unit that can output sound in multiple directions simultaneously. This universal design allows one module to perform the function of multiple specialized modules, reducing the total volume and weight required while maintaining expanded sound output range.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple sound output modules are used to achieve multi-directional sound coverage, then sound output range is improved, but weight increases

Engineering Contradiction:

Improvesound output rangeVSAvoidapparatus weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

Multiple sound output units with different orientations are merged into a single integrated sound output module. This consolidation achieves multi-directional sound coverage while minimizing the overall weight compared to using separate modules, as the units share common structural elements and housing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs thin-film or flexible membrane structures for the sound output surfaces, particularly in upward and downward facing units where rigid structures would add unnecessary weight. These thin-film solutions maintain acoustic performance while significantly reducing the weight of the apparatus.

Inventive Principle:

Principle #30Flexible shells and thin films
