Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rotary shaft and clutch buckle are added to enable composite motion for processing bevel keys, then the adaptability for processing slot keys with bevel teeth is improved, but the device complexity increases and the ease of operation deteriorates

Engineering Contradiction:

Improvecapability to process slot keys with bevel teethVSAvoidconvenience of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The clamp installation plate is segmented into two independently rotatable components: a first rotary component that rotates around a first axial line and a second rotary component that rotates around a second axial line. This segmentation allows each component to be controlled separately, enabling composite motion for processing bevel keys while maintaining operational simplicity through one-handed control.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamp installation plate transitions from a static structure to a dynamic one with two degrees of freedom, allowing it to rotate around two different axial lines. This dynamic capability enables the plate to achieve various angular positions for processing different key types, particularly slot keys with bevel teeth, while the user can control the motion conveniently with one hand.

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If two hands are used to hold the bench and installation plate for stable tooth feeding, then the manufacturing precision of key processing is improved, but the productivity deteriorates due to inability to perform simultaneous axial feeding

Engineering Contradiction:

Improvestability of tooth feedingVSAvoidcontinuity of processing

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The first rotary component and second rotary component are merged into a single integrated clamp installation plate structure that can perform composite motion. This merging allows the user to control both rotational movements with one hand, freeing the other hand to perform axial feeding operations simultaneously, thereby improving productivity while maintaining processing stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The clamp installation plate's dual rotary mechanism is designed to be self-contained and controllable with one hand, eliminating the need for two-handed operation. The structure itself provides the necessary stability for tooth feeding while allowing the user to perform additional feeding operations with the freed hand, creating a self-sufficient system that improves workflow efficiency.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the clamp installation plate is made rotatable around two axial lines for processing bevel keys, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

Improveability to process different key typesVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamp installation plate with dual rotary components serves multiple functions: it can process ordinary keys with straight teeth by rotating around one axial line, and process slot keys with bevel teeth by performing composite motion around two axial lines. This multi-functionality is achieved through a unified structure that integrates both rotational capabilities, avoiding the need for separate specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The rotary mechanism is nested within the clamp installation plate structure, with the first rotary component and second rotary component integrated into each other. This nesting approach allows the complex dual-rotation functionality to be contained within a compact design, minimizing the increase in device complexity while maximizing adaptability.

Inventive Principle:

Principle #7Nested doll (Nesting)
