Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the cuff-like element and radially projecting element are formed as a one-piece structure, then the structural stability is improved, but the manufacturing cost increases and flexibility decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The modular system divides the previously one-piece structure into separate components: a cuff-like element and a radially projecting element that can be detachably connected. This segmentation allows each component to be manufactured independently using simpler, more cost-effective processes while maintaining the overall structural stability through the connection mechanism between parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The radially projecting element is designed to be detachably connected to the cuff-like element, allowing one component to be attached to or nested within the other. This nesting approach enables separate manufacturing of components followed by assembly, reducing manufacturing complexity and cost while preserving structural integrity when assembled.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If the radially projecting element is fixed or immovably attached to the cuff-like element, then the structural stability is improved, but the adaptability to various shaft geometries decreases

Engineering Contradiction:
Improvestructural stabilityVSAvoidflexibility for various shaft geometries
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection between the radially projecting element and the cuff-like element is designed to be detachable rather than fixed, introducing dynamic reconfigurability to the system. This allows the radially projecting element to be positioned, removed, or replaced based on the specific geometry of different shafts, enhancing adaptability while maintaining structural stability when assembled.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The detachable connection design enables the modular system to serve multiple functions and adapt to various shaft geometries and cross-sections. The same cuff-like element can be used with different radially projecting elements configured for specific shaft types, making the system universally applicable across different installation scenarios.

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

3Ease of manufacture

If the radially projecting element is detachably connected to the cuff-like element, then the manufacturing cost is reduced and flexibility is enhanced, but the device complexity increases

Engineering Contradiction:
Improvemanufacturing costVSAvoiddevice complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

By segmenting the structure into detachable components, the system simplifies manufacturing processes for each individual part while the overall device complexity is managed through standardized connection interfaces. The segmentation allows for simpler, more cost-effective production of each component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable connection introduces a dynamic element that, while adding some complexity to the assembly mechanism, enables greater flexibility and adaptability. This controlled complexity is offset by the benefits of reduced manufacturing costs and enhanced versatility across different applications.

Inventive Principle:
Principle #15Dynamics
