Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional movement transmission mechanisms (epicyclic gear trains, crankshafts) are used, then the machine structure is simple and easy to manufacture, but the energy yield is not satisfactory and energy consumption is high
Solution Approach 1:
The mechanism is divided into independent functional modules: pendulum assembly, eccentric elements, cog wheels, and connecting rods. Each module performs a specific function (oscillation, force generation, motion transmission), allowing the system to achieve complex energy-saving motion through coordination of simple components rather than a single complex mechanism
Solution Approach 2:
The mechanism employs dynamic elements including a pendulum that oscillates, eccentric elements that rotate off-center, and connecting rods that transmit variable forces. These dynamic components create time-varying forces and motions that improve energy yield compared to static conventional mechanisms
2Productivity
If the mechanism uses eccentric elements and pendulum with slanting suspension rods to generate centrifugal forces and thrust forces, then energy efficiency is improved, but the device complexity increases
Solution Approach 1:
The pendulum acts as a counterweight system that oscillates to generate thrust and traction forces. The slanting suspension rods at 45-80 degrees create a mechanical advantage that amplifies these forces, enabling the mechanism to overcome friction and gravitational resistance more efficiently
Solution Approach 2:
The mechanism changes the orientation parameter of suspension rods to slanting angles between 45-80 degrees rather than vertical alignment. This parameter change optimizes the decomposition of gravitational force into thrust and traction components, significantly improving energy efficiency
3Loss of energy
If centrifugal forces are increased to facilitate rotation of cog wheels and eccentric elements, then energy consumption is reduced, but the mechanism requires higher initial driving force
Solution Approach 1:
The pendulum is designed to oscillate and build up centrifugal forces in advance before the cog wheels and eccentric elements need to rotate. This preliminary action stores energy in the oscillating pendulum, which then facilitates the rotation of other components with reduced additional force input
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism reduces the energy needed for cog wheels and eccentric elements to rotate by leveraging centrifugal forces, with the thrust or traction energy of the pendulum being significantly higher than the initial driving force, resulting in improved energy efficiency and yield.
Implementation Method 1
the equilibrium of the eccentric elements and the centrifugal forces that they generate enable to reduce the energy necessary for the cog wheels and the eccentric elements in rotation
Implementation Method 2
the thrust or traction forces resulting from the movements of the pendulum
Implementation Method 3
The cog wheels engage one with the other using a unitary transmission ratio and are mobile in rotation in opposing directions

AI summary
The present invention concerns a mechanism (1), comprising: one support (2) including a base (3), one pendulum (4), and connecting suspension rods (5) articulated on the base (3) and on the pendulum (4); two mobile cog wheels (12; 22) in rotation around their respective axis (A1; A2); two eccentric elements (14; 24) integral with the cog wheels (12; 22) in rotation and generating moments of gravity force around their axis (A1; A2); and one connecting link rod (60; 160) comprising a rotary head (62) and an eccentric head (63). The axis (A1; A2) are parallel within a horizontal or vertical reference plane (P0). The pendulum (4) supports the axis (A1; A2) of the cog wheels (12; 22) and of the eccentric elements (14; 24). The connecting rods (5) are slanting in accordance with an angle comprised between 45 degrees and 80 degrees in relation to a vertical plane. The cog wheels (12; 22) engage one with the other using a unitary transmission ratio and are mobile in rotation in opposing directions. When the mechanism (1) is in operation, the eccentric elements (14; 24) follow an elliptical movement, whereas the pendulum (4) follows a travel movement having a vertical component and a horizontal component. The moments of gravity force of the eccentric elements (14; 24) have a same value and a same direction, both being variable depending on their angular position around the axis (A1; A2). For each angular position of the cog wheels (12; 22) and of the eccentric elements (14; 24) around the axis (A1; A2), the mechanism (1) presents an equilibrium configuration at rest.
