Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If motion detection is implemented to enable gesture-based control, then ease of operation is improved, but device complexity increases due to additional sensors and control logic

Engineering Contradiction:
Improveease of control sequence switchingVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The motion sensor serves multiple functions: it detects both user gestures for control sequence switching and device motion for operational mode detection. This multi-functionality reduces the need for separate sensors and control logic, thereby improving ease of operation while minimizing the increase in device complexity.

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

Solution Approach 2:

The patent combines the gesture recognition function and the motion detection function into a single motion sensor unit. By merging these functions, the device achieves easier operation for control sequence switching without proportionally increasing complexity, as the same hardware component handles multiple control tasks.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple control sequences are made available for different operations, then adaptability is improved, but ease of operation deteriorates due to difficulty in switching between sequences

Engineering Contradiction:
Improvecontrol sequence adaptabilityVSAvoidease of control sequence switching
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent replaces manual switching mechanisms (such as physical buttons or menus) with motion-based gesture control. Users can switch between control sequences by performing specific gestures detected by the motion sensor, making the switching process more intuitive and easier to operate while maintaining adaptability across multiple control sequences.

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

Solution Approach 2:

The system automatically detects user gestures and switches control sequences based on the detected motion patterns. This self-service approach eliminates the need for users to manually navigate through menus or press multiple buttons, thereby improving ease of operation while preserving the adaptability of multiple control sequences.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If control sequence switching is enabled during substrate insertion, then ease of operation is improved, but reliability deteriorates due to potential interference with insertion operation

Engineering Contradiction:
Improvecontrol sequence switching during insertionVSAvoidreliability of substrate insertion
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements preliminary anti-action by detecting the substrate insertion motion first and temporarily disabling control sequence switching during this critical operation. The system recognizes the insertion gesture pattern and suppresses switching functions until the insertion is complete, thereby preventing interference and ensuring reliable substrate placement while still allowing ease of operation during normal usage.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The control system dynamically adjusts its responsiveness based on the detected operation state. During substrate insertion, the system transitions to a mode where control sequence switching is restricted, while during normal operation, switching is fully enabled. This dynamic behavior ensures reliability during critical operations while maintaining ease of operation during standard use.

Inventive Principle:
Principle #15Dynamics
