Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote probe technologies face challenges in providing controlled orientation and movement within confined or inaccessible spaces due to high power requirements for mechanical drive systems, which are often impractical in such environments.
Innovation Solution
The use of a rotatable external magnetic field to apply rotational forces to a remote object with a magnetic dipole, allowing for controlled orientation and movement without the need for a power source within the object, by manipulating the external magnet to change the object's support points and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical drive systems are used to provide movement capabilities to remote probes, then movement control is achieved, but power requirements become significant and difficult to provide within limited space
Solution Approach 1:
The patent replaces mechanical drive systems with a magnetic field-based actuation system. An external rotating magnetic field interacts with a magnetic dipole within the remote probe to generate rotational force, eliminating the need for mechanical motors and power sources inside the probe. This substitution resolves the contradiction by achieving movement control without significant power requirements.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the external controller and the remote probe. The rotating magnetic field serves as a mediator that transmits rotational force through space without direct mechanical contact, allowing controlled movement of the probe while avoiding the need for power-intensive mechanical drive systems within the probe itself.
2Ease of operation
If mechanical drive systems are used to provide movement capabilities to remote probes, then movement control is achieved, but device complexity increases due to power supply requirements
Solution Approach 1:
The patent replaces complex mechanical drive systems with a simple magnetic dipole and external rotating magnetic field system. This eliminates the need for motors, batteries, and power management circuits within the probe, significantly reducing device complexity while maintaining movement control capability.
Solution Approach 2:
The patent extracts the power supply and mechanical drive components from the remote probe, placing them externally. The probe itself only contains the magnetic dipole and sensing components, simplifying its design. The external rotating magnetic field generator handles all power-intensive functions outside the probe's limited space.
3Adaptability or versatility
If wireless capsules are carried by peristalsis or fluid flow, then movement through confined spaces is achieved, but orientation control is left to chance
Solution Approach 1:
The patent incorporates magnetic sensors within the probe to detect the orientation of the external rotating magnetic field. This feedback information is used to control the probe's orientation relative to the field, enabling precise directional control while maintaining the ability to move through confined spaces via the peristaltic-like motion induced by the rotating field.
Solution Approach 2:
The patent creates a dynamic interaction between the rotating external magnetic field and the magnetic dipole in the probe. This dynamic coupling enables the probe to actively adjust its orientation and movement direction in response to changing field conditions, providing both adaptability to confined spaces and controlled orientation capability.
