Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a conventional square-shaped charging box is used, then the structure is simple and easy to manufacture, but the endurance is short and insufficient electric energy is provided

Engineering Contradiction:
ImproveenduranceVSAvoidstructure complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The charging box incorporates a dynamic pendulum bob that swings freely within the box body, converting mechanical motion into electrical energy through electromagnetic induction. This dynamic component enables the box to generate additional energy during movement, extending its endurance while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces a purely mechanical energy storage system with an electromagnetic induction system. The pendulum bob equipped with a magnet interacts with a coil structure to generate electricity through relative motion, substituting mechanical energy conversion with electromagnetic energy conversion to achieve extended endurance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Quantity of substance

If a square-shaped charging box is used, then the manufacturing process is simple, but the charging capacity is insufficient

Engineering Contradiction:
Improvecharging capacityVSAvoidmanufacturing complexity
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The dynamic pendulum bob design allows the charging box to accumulate energy through repeated swinging motions. The magnet and coil arrangement enables multiple charging cycles during a single swing, effectively increasing the total charging capacity without requiring a proportionally larger battery or more complex manufacturing processes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pendulum bob's periodic swinging motion creates repeated instances of electromagnetic induction, allowing the coil to generate electricity multiple times during each swing cycle. This periodic energy generation increases the overall charging capacity while maintaining a simple manufacturing approach.

Inventive Principle:
Principle #19Periodic action

3Power

If the box body is designed with a curved bottom surface, then the swinging motion is enabled for energy generation, but the structural stability may be reduced

Engineering Contradiction:
Improveenergy generation capabilityVSAvoidstructural stability
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The curved bottom surface creates a stable equilibrium position for the pendulum bob, allowing it to swing naturally when disturbed while returning to its resting position. This dynamic design enables energy generation through swinging motion while the curved geometry itself provides structural stability by distributing forces evenly across the base.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pendulum bob acts as a counterweight that, when positioned at the lowest point of the curved surface, stabilizes the box structure. The gravitational force on the pendulum bob creates a restoring torque that returns the box to its stable equilibrium position, thereby maintaining structural stability while enabling swinging motion for energy generation.

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