Illuminated Powder Spray Cap for Dark Wind Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind detection methods fail to effectively determine wind direction in low-light or dark conditions, as they rely on visible reflection from powder clouds, which is not feasible in these conditions.
Innovation Solution
An illuminated wind detection device with a container for holding powder, a spray cap that disperses the powder and illuminates it with a built-in light, powered by a source within the cap, activated by a plunger mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a powder cloud is projected into the air to detect wind direction, then wind direction can be detected, but it cannot be seen in dark conditions
Solution Approach 1:
The patent combines the wind detection function with an illumination function by integrating a light source into the spray device. The light source is positioned to illuminate the powder cloud as it is dispensed, allowing the cloud to be visible in dark conditions while maintaining accurate wind direction detection capability.
Solution Approach 2:
The patent introduces a light source as an intermediary element that mediates between the powder cloud and the observer's vision in dark conditions. The light illuminates the powder particles, making them visible without interfering with the wind direction detection function.
2Illumination intensity
If a light source is added to illuminate the powder cloud, then visibility in dark conditions is improved, but device complexity increases
Solution Approach 1:
The patent merges the illumination function with the existing spray mechanism by integrating the light source into the spray cap or container structure. This combined design allows both functions to work together without requiring separate independent systems, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The spray device is designed to perform multiple functions: dispensing the powder cloud for wind detection and providing illumination for visibility in dark conditions. This multi-functionality reduces the need for separate dedicated devices, thereby limiting complexity increase.
3Duration of action of stationary object
If a power source is integrated into the spray cap, then continuous illumination is achieved, but weight and size of the device increase
Solution Approach 1:
The patent employs a disposable or replaceable power source (such as a battery) that can be easily replaced when depleted. This approach allows for extended illumination duration without permanently increasing the device's base weight, as the power source can be swapped rather than built-in as a permanent heavy component.
Solution Approach 2:
The patent may utilize high-efficiency, compact power sources such as lithium batteries or energy-dense battery technologies that provide extended illumination duration while minimizing weight and size increases. This parameter optimization allows longer operation without proportionally increasing device mass.
