Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex mechanical switching device with multiple components (bushings, cogs, springs, cams) is used, then the mode switching function is achieved, but the device complexity and manufacturing difficulty increase significantly
Solution Approach 1:
The patent replaces the complex mechanical switching system (bushings, cogs, springs, cams) with a magnetic field-based system using permanent magnets. The magnets interact with ferromagnetic elements to control the latch position, eliminating the need for complex mechanical components while achieving the same mode switching function.
Solution Approach 2:
The invention extracts and removes unnecessary mechanical components from the switching device. By using permanent magnets to provide the controlling force, the patent eliminates springs, cogs, and complex bushing assemblies, retaining only the essential latch mechanism and magnetic field generation elements.
2Ease of operation
If manual intervention is required to switch modes by moving and rotating bushings, then the switching function is achieved, but the ease of operation during performance deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the permanent magnets automatically control the latch position based on the pole's orientation. The magnetic field naturally attracts or repels ferromagnetic elements to engage or disengage the latch, eliminating the need for manual intervention and allowing performers to switch modes simply by rotating the pole to the appropriate position.
Solution Approach 2:
The switching mechanism becomes dynamic and responsive to the pole's position. The permanent magnets are positioned to create different magnetic field configurations that automatically activate based on whether the pole is in dynamic or static position, making the switching process intuitive and rapid without requiring separate manual操作步骤.
3Reliability
If multiple machine works and qualification assembly are required for manufacturing, then the switching device functionality is achieved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent replaces precision mechanical components that require extensive machining and assembly (bushings with cogs, spring mechanisms, cam profiles) with permanent magnets and simple ferromagnetic elements. These magnetic components can be manufactured using standard magnetizing processes and assembled with simple positioning, dramatically reducing manufacturing complexity while maintaining reliable switching functionality.
4Reliability
If the main recess for the latch is closed, then the magnetic lock is effective, but the ease of operation and accessibility deteriorates
Solution Approach 1:
The patent segments the recess structure into multiple parts: a main recess for magnetic engagement and an access slot or opening. The slot allows the latch to be manually manipulated when needed while the main recess provides the enclosed magnetic field environment for reliable automatic engagement. This segmentation enables both manual control and automatic magnetic locking to function effectively.

Function Achieved in This Case
Enables quick and effortless switching between dynamic and static modes without manual effort, enhancing performance and reducing manufacturing complexity, allowing for double-sided pylon designs with adjustable screw placement.
Implementation Method 1
the detail with the main recess for the latch is performed at least partially of magnetically soft material... the permanent magnet is installed in a cavity therefor with a sinking... ensuring that an attraction force of the permanent magnet to the detail with the main recess is more than attraction force of the permanent magnet to the latch
