Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the weight of the robot increases to provide more solidity and stronger torque, then the robot can support more components and perform more functions, but the agility and mobility are slowed and the cost increases

Engineering Contradiction:

ImprovetorqueVSAvoidagility

Core Design Contradiction:

StrengthVSSpeed

Solution Approach 1:

The patent applies the anti-weight principle by using a thruster to generate an upward propulsive force that counteracts the robot's weight. This allows the robot to effectively operate with reduced gravitational impact, enabling agile movements without requiring excessive structural strength or torque to support heavy components for weight compensation.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

2Strength

If the weight of the robot increases to provide more solidity and stronger torque, then the robot can support more components and perform more functions, but the robot takes a great deal of time to perform any posture or motion

Engineering Contradiction:

ImprovesolidityVSAvoidtime to perform posture

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The thruster-generated propulsive force counteracts the robot's weight, reducing the gravitational burden on the mechanical structure. This enables faster posture changes and motion execution without requiring excessive structural strength, thereby reducing the time needed to perform postures while maintaining solidity.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

3Ease of operation

If advanced components and hardware capable of high-level computation are used to control the posture of a heavy robot, then the posture control can be achieved, but the cost is increased and the types of components that can be used are limited

Engineering Contradiction:

Solution Approach 1:

The patent replaces the conventional mechanical approach of using heavy-duty components and advanced computational hardware for posture control with a propulsive force-based system. The thruster provides the necessary force to enable posture changes without requiring complex mechanical structures or high-performance computational hardware, thereby reducing component complexity and expanding component selection options.

Inventive Principle:

Solution Approach 1:

The patent substitutes the mechanical approach of increasing component quantity for solidity and torque with a propulsive force-based solution. The thruster provides the necessary force to enable various motions without requiring an increased number of mechanical components, thereby reducing manufacturing cost while maintaining versatility.
