Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional hair curler operation is used, then temperature control and curling function are achieved, but operator experience is required and operation becomes complex and cumbersome

Engineering Contradiction:
Improveease of operationVSAvoidoperation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The hair curling hammer incorporates automatic temperature control through PTC and NTC temperature sensors that monitor and regulate heating without user intervention. The motor automatically controls the rotation of the curling arm and steel wires, eliminating the need for manual operation and making the device self-regulating and easier to use.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device uses temperature sensors (PTC and NTC) to continuously monitor the temperature of the heat cover and provide feedback to the control system. This closed-loop feedback mechanism automatically adjusts the heating power to maintain optimal temperature, simplifying operation while ensuring consistent performance without requiring user experience.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple control functions are added for temperature and time adjustment, then user requirements are met, but device structure becomes more complex

Engineering Contradiction:
ImproveadaptabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control member integrates multiple functions including temperature regulation, timing control, and rotation direction control into a single unified interface. The motor serves multiple purposes by controlling both the curling arm rotation and the steel wire movement, reducing the need for separate mechanisms and simplifying the overall structure while maintaining versatility.

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

Solution Approach 2:

The patent combines the temperature control circuit, timing control circuit, and motor control circuit into an integrated control system managed by a single microcontroller or control chip. This merging of control functions into a unified electronic system reduces structural complexity compared to having separate mechanical control mechanisms for each function.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If detachable housing and modular components are used, then ease of repair and manufacturing are improved, but assembly complexity increases

Engineering Contradiction:
Improveease of manufactureVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The hair curling hammer is divided into distinct modular components including a detachable housing, a separate control member, a heating member assembly, and a power member assembly. Each module can be manufactured independently and assembled through standardized connections, simplifying manufacturing processes and enabling specialized production for each component while maintaining overall system integration.

Inventive Principle:
Principle #1Segmentation
