Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the underwater device uses a conventional integrated design, then it provides stable protection for electrical components, but it becomes large, complex, and time-consuming to adapt to different applications
Solution Approach 1:
The housing is divided into a first housing part and a second housing part that can be detachably connected. The cavity containing the hyperspectral camera is separated from the other cavity containing electrical energy storage device and electrical loads by a wall section. This segmentation allows the device to be disassembled for quick adaptation to different applications while maintaining protection during operation.
Solution Approach 2:
The connection between the first housing part and the second housing part is designed to be releasable and detachable, allowing the device structure to dynamically change from a closed protected state to an open accessible state. This enables quick adaptation to different applications by allowing easy access to and replacement of electrical components.
2Ease of operation
If the underwater device uses a sealed integrated housing, then it protects electrical components from water, but it requires significant time to install and remove electrical devices
Solution Approach 1:
The housing is segmented into detachable parts with a releasable connection, allowing the cavity to be accessed by separating the first housing part from the second housing part. This enables quick installation and removal of electrical devices without requiring complex sealing operations.
Solution Approach 2:
The wall section is pre-designed to completely separate the cavity from the other cavity in a watertight manner. This preliminary structural arrangement ensures that when the housing parts are detached for component replacement, water cannot accidentally enter the cavity, eliminating the need for time-consuming waterproofing procedures during maintenance.
3Adaptability or versatility
If the underwater device uses a compact modular design with detachable housing, then it allows quick adaptation and component access, but it risks water ingress during maintenance
Solution Approach 1:
The housing is divided into sealed segments with a wall section that completely separates the cavity from the other cavity. This segmentation maintains watertight protection for the hyperspectral camera in the cavity while allowing access to electrical components in the other cavity through the releasable connection between housing parts.
Solution Approach 2:
The wall section acts as an intermediary barrier between the cavity and the other cavity, completely preventing water from flowing into the cavity when the housing parts are detached. This intermediary structure enables quick adaptation while maintaining reliability by blocking the water ingress path.
4Measurement precision
If the underwater device surveys large areas with fine spatial resolution, then it captures detailed organism data, but it requires extensive time and resource consumption
Solution Approach 1:
The hyperspectral camera provides high spectral resolution with 30-200 contiguous channels, enabling the device to capture detailed information about diverse organisms. This multi-functional capability allows the same device to survey large areas efficiently while maintaining fine spatial resolution for detailed organism detection, addressing both measurement precision and productivity requirements.
