Solution Overview
Problem
Test boards on carrier carts are prone to sliding off during transportation due to uneven road surfaces or excessive speed, posing a risk of damage and instability.
Innovation Solution
A mobile device with a frame featuring movable rods and resettable components, including a reset member and limiting plate, limits the test boards in sliding regions to prevent sliding, and allows for easy insertion into testing slots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carrier cart has a free surface to allow test boards to slide out for insertion into slots, then the ease of operation is improved, but the stability of the test board during transportation deteriorates
Solution Approach 1:
The patent applies the dynamics principle by implementing movable limiting plates that can shift between two positions: a first position that restricts the test board during transportation to prevent sliding, and a second position that allows the test board to slide freely for insertion into the slot. This dynamic reconfiguration enables the system to adapt its stability characteristics based on operational requirements, resolving the contradiction between stability during transport and ease of insertion.
Solution Approach 2:
The patent employs parameter changes by modifying the position parameter of the limiting plates between two discrete states. When the limiting plates are in the first position, they constrain the test board's movement parameters; when shifted to the second position, they allow free movement. This parameter switching mechanism enables the system to transition between stable confinement and easy accessibility, effectively resolving the technical contradiction.
2Ease of operation
If the carrier cart allows free sliding of test boards for easy insertion, then the ease of operation is improved, but the reliability of preventing accidental falls deteriorates
Solution Approach 1:
The movable limiting plates dynamically adjust their position based on operational phase: during transportation, they occupy the first position to provide reliable containment and prevent accidental falls; during insertion operations, they shift to the second position to enable easy sliding. This dynamic behavior ensures both reliability during transport and ease of operation during insertion, resolving the contradiction between these two requirements.
3Stability of the object's composition
If the carrier cart has fixed limiting structures to prevent sliding, then the stability is improved, but the ease of operation for insertion deteriorates
Solution Approach 1:
The patent transforms fixed limiting structures into dynamic, movable limiting plates that can change their position and function. During transportation, the limiting plates are positioned to provide stable confinement; during insertion, they are moved to allow free access. This dynamic characteristic eliminates the need to choose between fixed stability and operational ease, as the system provides both at appropriate times.
Solution Approach 2:
The system changes the position parameter of the limiting plates between two states: a constrained state during transport that provides stability, and an unconstrained state during insertion that provides ease of operation. This parameter switching resolves the contradiction by allowing the system to optimize for stability or ease of operation depending on the operational context.
