Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual actuation mechanism is used for gripper jaws, then device complexity is reduced, but user effort and difficulty of operation increase

Engineering Contradiction:
Improveuser effort to actuate gripperVSAvoidelectromechanical system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical actuation system with an electromechanical system. The gripper jaws are actuated by an electromechanical actuator (motor-driven mechanism) controlled by control means, eliminating the need for manual lever manipulation and reducing user effort significantly.

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

Solution Approach 2:

The electromechanical system enables the gripper to automatically grasp and release the cooking vessel without continuous manual intervention. Once activated, the system self-regulates the gripping action through the control means, reducing the complexity of manual operation.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If simple mechanical structure is used, then ease of manufacture is improved, but multifunctionality is limited

Engineering Contradiction:
Improveadditional functionalitiesVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent integrates multiple functions into a single removable gripping device. The electromechanical system can be configured to provide gripping, mixing, stirring, or other cooking辅助 functions through programmable control means, making the device versatile while maintaining manufacturability through modular design.

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

Solution Approach 2:

The device incorporates a removable and interchangeable module system where functional components can be dynamically changed. The electromechanical actuator can drive different attachments (gripper jaws, mixing blades, etc.) allowing the same base structure to perform multiple functions without requiring complete redesign.

Inventive Principle:
Principle #15Dynamics

3Reliability

If electromagnetic connection means are used for recharging, then energy supply reliability is improved, but device complexity increases

Engineering Contradiction:
Improveenergy source rechargingVSAvoidelectromagnetic connection system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses electromagnetic connection means (inductive coupling) as an intermediary for wireless energy transfer between the removable gripping device and the cooking vessel or base station. This eliminates physical contact requirements and improves recharging reliability while the integration into the existing electromechanical system minimizes additional complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
