Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the throwing wheel device is fixed parallelly at front end and rear end, then the structure is simple, but the three throwing force gears are susceptible to rotational inertia force and gravity, resulting in unstable and unsmooth rotation

Engineering Contradiction:
Improvestructure simplicityVSAvoidrotation stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The device is divided into two rotatable discs (front and rear) with the central shaft rotatably locked on their centers. Each disc independently supports throwing force gears, allowing them to rotate separately and reducing mutual interference. This segmentation enables stable rotation by distributing the rotational load across multiple independent units rather than a single fixed parallel structure.

Inventive Principle:
Principle #1Segmentation

2Force

If conventional planetary gear type generating system is used, then large torque can be produced, but the throwing wheel device causes energy waste due to unstable rotation

Engineering Contradiction:
ImprovetorqueVSAvoidenergy waste
Core Design Contradiction:
ForceVSLoss of energy

Solution Approach 1:

Counterweight elements are disposed on the throwing force gears to balance the gravitational force and rotational inertia. These counterweights offset the unstable forces acting on the gears during rotation, enabling smooth and stable operation. This eliminates energy waste caused by unstable rotation while maintaining the large torque production capability of the planetary gear system.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

3Device complexity

If the generator immediately loses ability to generate electricity when there is no wind or water, then the system is simple, but the power generation is not continuous

Engineering Contradiction:
Improvesystem simplicityVSAvoidpower generation continuity
Core Design Contradiction:
Device complexityVSDuration of action of stationary object

Solution Approach 1:

The system uses two rotatable discs with throwing force gears that can rotate independently and continuously. The dynamic structure allows the gears to maintain rotation through their own momentum and the counterbalancing effect of counterweight elements, enabling continuous power generation without relying on external wind or water flow. This dynamic design maintains system simplicity while ensuring continuous operation.
