Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional underwater tracking cameras are used, then underwater surveillance capability is provided, but the system complexity and manufacturing cost increase significantly

Engineering Contradiction:
Improveunderwater surveillance capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the trigger weight function with the camera mounting platform into a single integrated device. The trigger weight serves dual purposes: providing the necessary weight for the coring operation and simultaneously supporting the camera and accessories. This merging eliminates the need for separate control systems for both the coring operation and camera stabilization, thereby reducing overall system complexity while maintaining reliable underwater surveillance capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The trigger weight device is designed as a multi-functional platform that performs multiple functions: (1) provides ballast weight for the coring operation, (2) mounts and stabilizes the camera, (3) supports additional accessories like lights and laser scalers, and (4) serves as a positioning structure. This universality allows a single device to replace what would otherwise require multiple separate components and control systems, reducing complexity while ensuring reliable surveillance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If conventional underwater tracking cameras are used, then underwater imaging is achieved, but manufacturing cost and implementation difficulty increase

Engineering Contradiction:
Improveunderwater imaging qualityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The camera mounting platform is designed as a modular, segmented structure with separate mounting points and attachment mechanisms. This segmentation allows the system to be assembled from standard, off-the-shelf components rather than requiring custom-manufactured integrated units, significantly reducing manufacturing costs while maintaining the ability to provide high-quality underwater imaging.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The platform utilizes simple, inexpensive materials and construction methods that prioritize functionality over durability of the platform itself. The focus is on creating a cost-effective solution that achieves the imaging goal for each deployment, rather than investing in expensive, highly durable conventional camera systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If conventional underwater tracking cameras are used, then tracking capability is provided, but equipment stability and positioning accuracy deteriorate

Engineering Contradiction:
Improvetracking capabilityVSAvoidcamera stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The trigger weight itself serves as a counterweight that stabilizes the camera platform. By positioning the camera and accessories on this weighted platform, the system achieves inherent stability without requiring additional active stabilization systems. The weight provides a stable base that resists displacement and maintains correct positioning and orientation for tracking underwater objects and processes.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

4Reliability

If conventional underwater tracking cameras are used, then surveillance function is provided, but time consumption for deployment and inspection increases

Engineering Contradiction:
Improvesurveillance functionVSAvoiddeployment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The camera and accessories are pre-mounted on the trigger weight platform before deployment. This preliminary assembly eliminates the need for time-consuming on-site installation and configuration during the actual deployment process. The system is ready for immediate use upon deployment, significantly reducing the time required for setup and inspection while maintaining reliable surveillance functionality.

Inventive Principle:
Principle #10Preliminary action
