Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic inspection apparatuses are deployed in cable trenches, then cable inspection capability is improved, but the apparatuses malfunction when water accumulates in the trench
Solution Approach 1:
The patent applies the anti-weight principle by using buoyancy force from water accumulation to lift the inspection apparatus above the water surface through a float component. When water accumulates in the cable trench, the float component activates, raising the apparatus via a lifting frame and pull rope mechanism, preventing water contact with electronic components and ensuring continued operation.
2Duration of action of moving object
If inspection apparatus wades through water accumulation, then continuous inspection is maintained, but the monitoring component and driving component are damaged
Solution Approach 1:
The patent implements preliminary anti-action by detecting water accumulation in advance and activating the lifting mechanism before water can contact and damage the monitoring and driving components. The float component senses water presence and preemptively raises the apparatus, preventing the harmful effect of water exposure before it occurs.
3Reliability
If float component lifts the device above water, then component protection is improved, but device complexity increases
Solution Approach 1:
The patent applies the self-service principle by designing a float component that automatically activates and operates the lifting mechanism when water accumulation is detected. The system self-regulates based on water presence, eliminating the need for complex external control systems, sensors, or manual intervention, thereby achieving component protection with relatively simple structure.
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 device avoids damage from water contact, enabling timely detection and drainage of accumulated water, facilitating continuous cable inspection and reducing maintenance costs.
Implementation Method 1
the float component drives the main body to rise along the lifting frame under the buoyancy force of the accumulated water
Implementation Method 2
After the accumulated water is drained, the float component drives the main body to descend along the lifting frame under its own gravity

AI summary
The present invention discloses a cable inspection device, including a main body, a monitoring component, a driving component and a water-wading component. The monitoring component is disposed on the main body, and is adapted to acquire and output a monitoring signal. The driving component is disposed at the bottom of the main body, and is adapted to be movably connected to a cable. The water-wading component is movably connected to the main body, and has a protection state that drives the driving component away from the cable, and a movement state that drives the driving component to contact the cable. The water-wading component can drive the main body away from the water surface, avoiding damage to the components by the accumulated water. The monitoring component can output a monitoring signal at the water accumulation location, so that the staff can timely drain the accumulated water in the cable trench.
