Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rocker is swung by user's arm force, then the rocker can be rotated to control directions, but the uncontrollable force magnitude and swinging resistance cause poor user experience
Solution Approach 1:
The patent replaces the purely mechanical rocker system with an electromechanical system by introducing a coil assembly that generates electromagnetic force to interact with the magnetic assembly on the rocker. This substitution allows electronic control of the force applied to the rocker, replacing uncontrollable manual force with precisely controllable electromagnetic force, thereby improving force magnitude control and overall manipulation experience.
Solution Approach 2:
The patent changes the physical state and parameters of the force application system by introducing electromagnetic interaction. The coil assembly can dynamically adjust the magnitude and direction of force applied to the rocker through electrical signal control, transforming the fixed mechanical force characteristics into variable electromagnetic force characteristics, thus enabling precise control over force magnitude.
2Stability of the object's composition
If the rocker has swinging resistance, then the rocker provides stable rotation baseline, but the resistance reduces manipulation smoothness and comfort
Solution Approach 1:
The patent substitutes the mechanical friction-based resistance system with an electromagnetic force system. The coil assembly generates controllable electromagnetic forces that can compensate for or reduce the effects of mechanical swinging resistance, allowing the system to maintain rotational stability while improving manipulation smoothness by electronically counteracting resistive forces.
Solution Approach 2:
The patent applies preliminary anti-action by using the coil assembly to generate electromagnetic forces that preemptively counteract the swinging resistance before it affects manipulation smoothness. The system can detect and compensate for resistance forces in advance, maintaining stable rotation while ensuring smooth user manipulation.

AI summary
A manipulating device comprising: a rocker, a supporting member a magnetic assembly and a coil assembly, wherein the rocker is rotatable around the supporting member; the coil assembly is disposed opposite to the rocker, the magnetic assembly is disposed on one end of the rocker adjacent to the coil assembly; the magnetic assembly (3) comprising a central magnet (31) and at least one side magnets. By providing the magnetic assembly on the one end of the rocker adjacent to the coil assembly (4), the power for rotating the rocker is adjusted by interaction force between the magnetic assembly and the coil assembly, and the interaction force between the magnetic assembly and the coil assembly can be further adjusted by adjusting the magnitude of the current of the coil assembly.
