Light-Shielding Cover for Mobile Measuring Apparatus Shadow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile measuring apparatuses face challenges in accurately detecting measurement targets due to shadows caused by the measuring device, its frame, and harness, especially under light sources like the sun, tunnel illumination, and street lights, leading to irregular shadows and potential erroneous detection of road surface conditions.
Innovation Solution
Incorporating a light-shielding cover between the vehicle and the measuring device to block light from reaching the road surface, thereby simplifying the shadow shape and reducing boundaries between shadow and non-shadow areas in captured images, ensuring accurate measurement of road surface conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a measuring device is mounted on a mobile object to capture external environment, then measurement capability is provided, but complex shadows are generated on the measurement target
Solution Approach 1:
A light-shielding cover is introduced as an intermediary component between the mobile object and the measuring device. This cover blocks light from reaching the measurement target through the harness and frame, thereby preventing complex shadow formation while maintaining the measuring device's functionality.
Solution Approach 2:
The light-shielding cover is designed as a separate, modular component that can be independently attached to the mobile object. This segmentation allows the shadow-control function to be added without modifying the core measuring device structure, maintaining adaptability while solving the shadow problem.
2Object-generated harmful factors
If light-shielding cover is added to block light from reaching measurement target, then shadow complexity is reduced, but device complexity increases
Solution Approach 1:
The light-shielding cover serves as a simple intermediary barrier that requires minimal structural complexity. It is designed as a basic light-blocking component that can be easily integrated without adding complex mechanisms or control systems.
Solution Approach 2:
The light-shielding cover is designed as a simple, potentially disposable component rather than a complex permanent structure. This approach reduces overall device complexity by using a straightforward light-blocking element that can be easily replaced or adjusted if needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The light-shielding cover effectively prevents complex shadow formation, reducing erroneous determinations of road surface damage and allowing for successful measurement of road surface properties like unevenness, rutting depth, and crack ratio, enhancing the accuracy of maintenance control indices.
