Solution Overview
Problem
Existing environment condition measurement devices using sound waves face challenges in effectively measuring conditions in non-cubic spaces due to significant sound wave attenuation and data loss in propagation paths, particularly when sound wave units do not face each other directly.
Innovation Solution
The environment condition measurement device employs sound wave units installed at corner portions of a measurement space with inclined directivity axes relative to boundary planes, ensuring equal installation angles and symmetrical orientations to minimize sound wave attenuation and enhance data propagation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound wave units are installed on boundary planes of non-cubic measurement spaces, then the device can measure environment conditions in diverse space shapes, but significant sound wave attenuation and data loss occur in propagation paths
Solution Approach 1:
The patent applies local quality by configuring sound wave units with specific installation angles tailored to their local positions on boundary planes. Each sound wave unit's directivity axis is inclined at a predetermined angle relative to the boundary plane, creating locally optimized sound wave propagation paths that adapt to the global non-cubic space shape while maintaining reliable measurements.
Solution Approach 2:
The patent changes the installation angle parameter of sound wave units relative to boundary planes. By inclining the directivity axis at a predetermined angle rather than installing units perpendicular to boundary planes, the system optimizes sound wave propagation characteristics and reduces attenuation in non-cubic measurement spaces.
2Ease of manufacture
If sound wave units are installed with directivity axes perpendicular to boundary planes, then installation is simple, but sound wave propagation efficiency decreases and data loss increases
Solution Approach 1:
The patent modifies the installation angle parameter from perpendicular (90 degrees) to an inclined predetermined angle relative to the boundary plane. This parameter change optimizes the directivity axis orientation to improve sound wave propagation efficiency and reduce data loss in non-cubic measurement spaces.
3Reliability
If sound wave units are inclined at predetermined angles relative to boundary planes, then sound wave propagation efficiency improves and data loss reduces, but installation complexity increases
Solution Approach 1:
The patent applies local quality by providing specific installation angle guidance for each sound wave unit based on its position on the boundary plane. This localized configuration approach maintains measurement reliability while managing installation complexity through clear, position-specific orientation instructions.
Solution Approach 2:
The patent applies preliminary action by pre-calculating and specifying the predetermined inclination angles for sound wave units before installation. This allows installers to follow predetermined orientation guidelines, reducing on-site decision-making complexity while ensuring optimal propagation paths are achieved.
