Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack the capability to perform effective underwater photographing and inspection in muddy water areas due to limited light penetration and sediment interference.
Innovation Solution
A photographing apparatus comprising a camera, a light supplementing structure, and a closed housing with a transparent photographing portion, which emits light to the object and allows the camera to capture images through the portion, integrated with an inspection device that includes a rack, lifting, and dredging mechanisms to clear sediment, enabling clear underwater imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional photographing methods are used in muddy water areas, then the apparatus structure remains simple, but clear underwater imaging cannot be achieved due to insufficient lighting and sediment interference
Solution Approach 1:
The patent combines multiple functions into an integrated apparatus: the housing serves as both protective enclosure and mounting structure, the photographing portion integrates optical window and sealing functions, and the light supplementing structure merges illumination with the housing body. This consolidation achieves clear underwater imaging while controlling overall device complexity.
Solution Approach 2:
The transparent photographing portion acts as an intermediary between the external muddy water environment and the internal camera system. It allows light transmission while protecting the camera from water ingress, and the light supplementing structure serves as an intermediary to provide adequate illumination through the photographing portion to the target object.
2Measurement precision
If light supplementing structure is added to improve underwater visibility, then imaging quality improves, but energy consumption increases
Solution Approach 1:
The light supplementing structure provides illumination locally at the photographing portion rather than requiring system-wide lighting. The lights are positioned to illuminate only the immediate area of interest through the photographing portion, reducing overall energy consumption while maintaining adequate lighting for clear imaging of the target object.
3Illumination intensity
If photographing portion is made transparent for imaging, then light transmission improves, but structural strength and sealing performance deteriorate
Solution Approach 1:
The photographing portion utilizes composite construction combining transparent materials (for light transmission) with reinforcing structures (for strength and sealing). The transparent portion allows adequate light passage while the composite design provides necessary mechanical strength to withstand water pressure and maintain sealing performance against the housing.
