Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the electronic device uses a conventional flat structure with single-directional sound transmission, then the device structure is simple, but the sound transmission directionality is limited

Engineering Contradiction:
Improvesound transmission directionalityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The electroacoustic component is divided into multiple independent sound output units (first sound output unit and second sound output unit) positioned at different locations. Each unit can independently transmit sound signals in its own direction, enabling multi-directional sound transmission without requiring a completely redesigned structural framework.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from single-directional sound transmission to multi-directional transmission by adding spatial dimensionality. The first sound output unit transmits in a first direction while the second sound output unit transmits in a second direction, creating sound propagation in multiple spatial dimensions simultaneously.

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

2Adaptability or versatility

If multiple electroacoustic holes are added for multi-directional sound transmission, then sound transmission capability improves, but manufacturing complexity increases

Engineering Contradiction:
Improvesound transmission capabilityVSAvoidmanufacturing process
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The electroacoustic component is segmented into multiple independent sound output units, each with its own electroacoustic hole. This segmentation allows each hole to be manufactured independently using standard drilling processes, and the units can be assembled together, simplifying the overall manufacturing compared to creating a single complex multi-directional transmission structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electroacoustic holes serve multiple functions: they provide sound transmission paths for different directions, act as structural support elements, and can be integrated with the device housing. This multi-functionality reduces the need for additional separate components, thereby simplifying manufacturing.

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