Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multiple transducers are disposed on a plane to control object motion, then the device can generate force to move objects, but wave energy is lost due to varying distances between transducers and the object
Solution Approach 1:
The patent applies spherical geometry by positioning transducers on the surface of an imaginary sphere rather than a plane. This ensures that all transducers are equidistant from the center point where the object is located, eliminating wave energy loss due to distance variation. The curved spherical arrangement maintains consistent energy transfer efficiency across all transducers.
Solution Approach 2:
The invention transitions from a two-dimensional planar arrangement of transducers to a three-dimensional spherical arrangement. By adding the dimensional aspect of radius (distance from center), the system achieves uniform distance from all transducers to the object at the sphere's center, resolving the energy loss problem inherent in planar configurations.
2Manufacturing precision
If transducers are arranged on a plane, then the device structure is simple, but it is difficult to control precise motion such as rotational motion
Solution Approach 1:
The link unit employs spherical geometry with transfer parts positioned on an imaginary sphere. This curved arrangement enables precise control of both translational and rotational motions by allowing force vectors to be applied from multiple directions converging at the center, achieving superior motion control precision compared to planar arrangements.
Solution Approach 2:
The link unit incorporates movable link parts that can dynamically adjust their positions and orientations. This dynamic capability allows the system to adaptively control the direction and magnitude of forces applied to the object, enabling precise control of complex motions including rotation, while the spherical geometry maintains structural elegance.
3Use of energy by moving object
If transducers are placed at varying distances from the object, then the device can cover a larger area, but energy efficiency decreases
Solution Approach 1:
By arranging transducers on a spherical surface, the system achieves uniform energy efficiency across all transducers while maintaining a compact footprint. The spherical geometry ensures that each transducer operates at optimal distance from the object, preventing energy loss despite the limited spatial footprint compared to planar expansions.

AI summary
A force generating device includes: a support unit; a link unit rotatably coupled to one side of the support unit; a transfer unit that is coupled to the link unit and transfers wave energy to the outside; and a drive unit that operates the link unit. In particular, the transfer unit is moved on an imaginary sphere by a motion of the link unit, and the transfer unit transfers the wave energy to a center of the imaginary sphere.
