Solution Approach 1:

The invention transitions from single-direction (vertical or rotational) power generation to multi-directional power generation by incorporating hinge connection units that can rotate around horizontal axes. This allows the moving body to convert kinetic energy from movements in various directions including diagonal and spiral motions, effectively adding dimensional versatility to the power generation system

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The invention employs dynamic hinge connection units that can adaptively change their rotation axes and orientations based on the direction of external forces. The connector with hinge joints allows the system to dynamically respond to wind, tidal, or wave forces from any direction, converting kinetic energy efficiently regardless of the force direction

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a moving body is used to convert kinetic energy from various directions, then power generation versatility improves, but device complexity increases due to hinge connection units and multiple conversion mechanisms

Engineering Contradiction:

Solution Approach 1:

The hinge connection unit serves multiple functions simultaneously: it acts as a connector between the moving body and support structure, provides rotational freedom for multi-directional movement, and enables kinetic energy conversion through its rotation. This multi-functionality reduces the need for separate components for each function, thereby managing complexity while maintaining versatility

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention divides the power conversion system into modular components: the moving body, the connector with hinge joints, and the power conversion unit. This segmentation allows each component to be optimized independently and facilitates easier maintenance and scalability, managing overall system complexity

Inventive Principle:
Principle #1Segmentation
