Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the sound pickup hole is disposed in a conventional location, then the device structure is simple, but the sound pickup quality is poor due to wind noise interference during motion

Engineering Contradiction:

Improvesound pickup qualityVSAvoidwind noise interference

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The sound pickup hole is relocated from a conventional location to the hollow portion of the concave structure, utilizing the three-dimensional space created by the concave geometry. This dimensional repositioning allows the sound pickup hole to be situated in a location that is naturally shielded from wind flow, thereby improving sound pickup quality while maintaining structural simplicity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The concave structure, which initially might be seen as an aesthetic or structural feature, is utilized to create a hollow portion that serves as a wind shield. The concave geometry that could potentially catch wind is instead designed to redirect airflow away from the sound pickup hole, converting a potential harmful interaction with wind into a beneficial shielding effect.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If the sound pickup hole is disposed at the hollow of concave portion, then the wind noise interference is reduced, but the device structure becomes more complex

Engineering Contradiction:

Improvewind noise interferenceVSAvoidhousing structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The concave structure serves multiple functions: it provides the structural form of the housing, creates the hollow portion that shields the sound pickup hole from wind, and defines the positional relationship between the sound pickup hole and other components. By making the concave structure multi-functional, the design avoids adding separate complex wind shielding components while still achieving wind noise reduction.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wind shielding function is merged with the housing structure itself through the concave geometry. Instead of adding a separate shield or enclosure, the concave portion of the housing is designed to inherently provide wind protection, combining the structural and acoustic shielding functions into a single integrated feature.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If the first sound pickup hole is disposed at the bottom of the hollow, then the wind noise is minimized, but the sound pickup directionality is affected

Engineering Contradiction:

Improvewind noiseVSAvoidsound pickup directionality

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The concave structure creates different local acoustic environments: the hollow portion provides wind shielding while the opening orientation maintains sound pickup capability. The local geometry of the concave structure is optimized to provide wind protection in the direction of airflow while preserving the sound pickup function in the desired direction, allowing both wind noise reduction and directional sound pickup to coexist.
