Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current quick release connection designs are used, then basic locking function is achieved, but reconfigurability for diverse applications is limited

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

Solution Approach 1:

The quick release connection is designed with a universal interface that can accommodate different ball sizes and configurations, allowing a single device type to serve multiple applications across various manufacturing sectors. The standardized female component with adjustable ball positioning enables the same connection system to adapt to different structural requirements without needing multiple specialized connection types.

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

Solution Approach 2:

The connection system is divided into modular components: a standardized female component, interchangeable male components, and adjustable ball positioning mechanisms. This segmentation allows individual parts to be replaced or reconfigured independently, enabling easy adaptation to different applications while maintaining a simple overall system architecture.

Inventive Principle:
Principle #1Segmentation

2Weight of moving object

If traditional quick release connections are used, then locking function is provided, but size, weight, and encumbrance are not optimized

Engineering Contradiction:
Improveconnection weightVSAvoidmechanical resistance
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The connection design optimizes parameters such as ball diameter, cam lever dimensions, and material properties to achieve the minimum weight necessary for reliable operation. The female component is designed with precise wall thickness and reinforcement only where structurally necessary, reducing unnecessary material while maintaining mechanical resistance and locking reliability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The connection components utilize composite material construction, combining materials with different properties to achieve optimal strength-to-weight ratios. The female component may use reinforced polymers or metal-composite structures that provide high mechanical resistance with minimal weight, while the balls and cam elements use materials optimized for friction and wear characteristics.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If existing quick release systems are used, then basic operation is achieved, but production costs are high

Engineering Contradiction:
Improveproduction costVSAvoidnumber of parts
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

Multiple functions are merged into single components to reduce the total number of parts. The female component integrates the body, ball positioning mechanism, and locking interface into one piece. The cam lever combines the unlocking action, ball retraction, and locking engagement functions. This merging simplifies manufacturing and assembly while reducing part count and production costs.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

A standardized female component design serves as a universal base that can work with various male component configurations. This universality allows for economies of scale in manufacturing the common female component, reducing per-unit costs while still providing adaptability for different applications through interchangeable male components and ball positioning.

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

4Adaptability or versatility

If prior art quick release connections are used, then locking mechanism is provided, but modular flexibility is insufficient

Engineering Contradiction:
Improvemodular flexibilityVSAvoidergonometry
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connection system is segmented into independently configurable modules: the female component with adjustable ball positions, various male component types, and interchangeable locking mechanisms. This segmentation enables modular assembly where only the necessary components are combined, providing flexibility without overwhelming complexity in operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ball positioning mechanism within the female component is designed to be dynamically adjustable, allowing the operator to reposition balls along predetermined guides during assembly. This dynamic configurability provides modular flexibility while maintaining simple operation, as the adjustment mechanism is integrated into the assembly process rather than requiring separate complex procedures.

Inventive Principle:
Principle #15Dynamics
