Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional pressure regulation methods are used, then fluid pressure can be maintained, but dynamic adjustment to match pre-selected amplitude and frequency values is not achieved
Solution Approach 1:
The patent replaces conventional mechanical pressure regulation mechanisms with a magnetically driven system. An electromagnetic force generator creates magnetic fields that act on a flexible member containing magnetic particles, causing it to flex and change the volume of the enclosed space. This substitution of mechanical actuation with magnetic field control enables precise dynamic pressure adjustment matching pre-selected amplitude and frequency values while reducing mechanical complexity.
Solution Approach 2:
The patent utilizes changes in magnetic field parameters (strength, frequency) to control the flexure of the flexible member. By varying the electrical current supplied to the electromagnetic force generator, the magnetic field parameters are changed, which directly controls the amplitude and frequency of flexible member flexure, thereby dynamically adjusting fluid pressure to match pre-selected values.
2Manufacturing precision
If magnetic force generators are used to control flexible member flexure, then precise pressure control is achieved, but device complexity increases
Solution Approach 1:
The patent employs a flexible member containing magnetic particles that responds to magnetic fields. This flexible membrane structure allows precise volume changes of the enclosed space when actuated by magnetic forces, enabling accurate pressure control. The flexible member's ability to deform elastically under magnetic influence provides precise control without requiring complex mechanical linkages or actuators.
Solution Approach 2:
The patent introduces a flexible member containing magnetic particles as an intermediary between the electromagnetic force generator and the fluid. This intermediary converts electrical signals to magnetic field variations, which then translate to mechanical flexure and volume changes, providing precise pressure control while isolating the complexity of magnetic field generation from the pressure control mechanism.
3Ease of operation
If the volume of enclosed space is changed to adjust pressure, then fluid pressure and flow can be controlled, but the mechanism for volume change becomes complex
Solution Approach 1:
The patent replaces complex mechanical volume control mechanisms (such as pistons, diaphragms with mechanical actuators, or variable geometry chambers) with a magnetically driven flexible member. The electromagnetic force generator creates magnetic fields that directly cause the flexible member to flex, changing the enclosed space volume in a simple and controllable manner, making pressure adjustment easy through electrical control.
Solution Approach 2:
The patent creates a dynamic volume control system where the flexible member continuously changes shape in response to varying magnetic field inputs. This dynamic response allows real-time pressure adjustment to match pre-selected amplitude and frequency values, replacing static or slowly responsive mechanical volume control mechanisms with a fast, electronically controllable magnetic system.
