Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid connection is used between the magnetic control device and the main body, then the connection stability is improved, but the adaptability to uneven ground environments deteriorates
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid fixed connection with a dynamic suspension system. The magnetic control device is suspended through a suspension member that can dynamically adjust its posture, allowing the system to adapt to uneven ground while maintaining connection stability through active control mechanisms.
Solution Approach 2:
The patent implements parameter changes by using an adsorption component that can change its adsorption force to control the suspension member's posture. By adjusting the adsorption force parameter, the system can lock or adjust the suspension member's position, enabling adaptation to different ground conditions while maintaining stable connection.
2Reliability
If the magnetic control device is fixedly installed, then the connection stability is improved, but the mobility and ease of operation deteriorates
Solution Approach 1:
The patent resolves this contradiction by creating a mobile magnetic control system where the magnetic control device can be moved to different locations while maintaining stable connection through the suspension system. The suspension member with adjustable posture control allows the device to be relocated and then stabilized for operation.
Solution Approach 2:
The suspension member acts as an intermediary between the mobile magnetic control device and the main body. It provides the necessary isolation and adjustment capability, allowing the device to be mobile during transport while maintaining stable connection during operation through posture control.
3Ease of operation
If a mobile magnetic control system is used, then the ease of operation is improved, but the stability under tilted conditions deteriorates
Solution Approach 1:
The patent addresses this issue by using the adsorption component to change the adsorption force parameter, which controls the suspension member's posture. When tilt is detected or anticipated, the system adjusts the adsorption force to reposition the suspension member and compensate for the tilt, maintaining operational stability in mobile conditions.
4Reliability
If the suspension member is always locked, then the connection stability is improved, but the ability to adjust posture deteriorates
Solution Approach 1:
The patent applies periodic action through the adsorption component that periodically adjusts the suspension member's posture. The system alternates between locked and adjustable states, using periodic adsorption force changes to maintain stability during operation while enabling posture adjustment when needed, such as during setup or when environmental conditions change.
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 suspension device maintains stability and ensures accurate posture adjustment of the magnetic control device, enhancing the reliability and effectiveness of capsule endoscope examinations.
Implementation Method 1
an adsorption component (400), which is disposed above the intermediate member (300)... when the adsorption component (400) has an adsorption force, the intermediate member (300) is driven to move vertically
Implementation Method 2
the suspension device comprises at least one elastic member, and the at least one elastic member applies an elastic force on the intermediate member such that the suspension member and the pairing portion abut against each other

AI summary
A suspension device and a capsule endoscope magnetic control system are provided. The suspension device includes a base, including a pairing portion; a suspension member, at least part of the suspension member is disposed within the base; an intermediate member, which is disposed on an upper end of the suspension member; and an adsorption component, which is disposed above the intermediate member. When the adsorption component has no adsorption force, the intermediate member is pressed against the upper end of the suspension member so that at least part of the suspension member abuts against the pairing portion and the suspension member is locked. When the adsorption component has the adsorption force, the intermediate member is driven to move vertically so that at least part of the suspension member is separated from the pairing portion and a posture of the suspension member is appropriate for adjustment.
