Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transport devices are used to transport living body specimens, then the specimens can be moved from one location to another, but the specimens are prone to adhere onto inner walls of containers due to vibration and shaking, causing loss of viability
Solution Approach 1:
The patent employs a dynamically adjustable support structure that can adapt its orientation during transport. The support structure includes adjustable support members that can be positioned at different angles to maintain the container in an optimal vertical orientation despite vehicle motion, preventing specimens from adhering to container walls
Solution Approach 2:
The patent changes the physical parameters of the transport system by using adjustable support members with variable angles and positions. This allows the container orientation to be dynamically adjusted to maintain vertical positioning of specimens throughout the transport process, counteracting the effects of vibration and shaking
2Duration of action of stationary object
If conventional transport devices are used, then specimens can be transported, but the transportation conditions are unstable causing specimens to deteriorate after long term transport
Solution Approach 1:
The patent uses dynamically adjustable support structures that can adapt to different transport durations and conditions. The adjustable support members can be repositioned throughout the transport journey to maintain optimal specimen orientation and environmental stability, enabling reliable long-term transport
Solution Approach 2:
The transport device incorporates multi-functional components including temperature control systems, humidity control systems, and adjustable mechanical supports that work together to provide stable transportation conditions for extended periods, making the device suitable for both short-term and long-term specimen transport
3Device complexity
If specimens are transported in containers without vertical stabilization, then the transport device structure is simple, but the specimens may not be soaked in preservation solution constantly
Solution Approach 1:
The patent implements a relatively simple yet effective dynamic support system with adjustable support members that can be positioned to maintain container verticality. This moderately complex mechanism ensures specimens remain submerged in preservation solution without requiring overly complicated stabilization systems
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 ensures stable and safe transport, reduces contamination, and maintains specimen viability by keeping specimens submerged in preservation solution, while facilitating efficient tracking and monitoring, thus adhering to GTP standards.
Implementation Method 1
A center of gravity of the storage assembly is lower than a pivoting point between the rotating bracket and the frame in location and is lower than a pivoting point between the storage assembly and the rotating bracket in location... the rotating brackets and the storage assemblies can rotate to be vertical by themselves because of the gravity

AI summary
A living body specimen transport device for receiving multiple living body specimens has a frame, a rotating bracket, and a storage assembly. The rotating bracket can be rotated with respect to the frame. The storage assembly can receive a container with a living body specimen and be rotated with respect to the rotating bracket. A center of gravity of the storage assembly is lower than a pivoting point where the rotating bracket is mounted on the frame and a pivoting point where the storage assembly is mounted on the rotating bracket. With such structure, even when the living body specimen transport device is vibrated and shaken during transporting and then the frame of the living body specimen transport device is tilted or turned over, the rotating bracket and the storage assembly can rotate to be vertical by themselves, which keeps the living body specimen being soaked in the preservation solution.
