Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional manufacturing processes are used to manufacture end effectors with intricate sub-substructures, then manufacturing precision can be achieved, but productivity is significantly reduced and manufacturing cost increases

Engineering Contradiction:
Improvemanufacturing precisionVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent changes the manufacturing parameter from traditional subtractive or assembly-based methods to additive manufacturing (3D printing). This parameter change enables the production of intricate sub-substructures that would be difficult or impossible to manufacture traditionally, while simultaneously improving productivity by creating complex geometries in a single manufacturing process rather than through multiple assembly steps.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If conventional interface methods are used with nozzles of nodes, then compatibility is maintained, but the manufacturing process becomes time-consuming and inefficient for mass assembly

Engineering Contradiction:
ImprovecompatibilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The end effector is segmented into distinct functional components: a body portion that interfaces with the nozzle, a retention feature portion with movable retention features, and integrated fluid channels. This segmentation allows each component to be optimized independently while maintaining overall compatibility with existing nozzle interfaces, and the modular design facilitates faster manufacturing and assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The end effector design incorporates multiple functions within a single component: it provides mechanical retention of the nozzle through movable retention features, fluid distribution through integrated channels, and structural support. This multi-functionality eliminates the need for separate components, reducing assembly time while maintaining adaptability to various nozzle configurations.

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

3Adaptability or versatility

If intricate sub-substructures are incorporated into end effectors to improve functionality, then device capability is enhanced, but device complexity increases making manufacturing more difficult

Engineering Contradiction:
Improvedevice capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions and structural elements into a single integrated end effector component. The body portion, retention features, and fluid channels are combined into one additively manufactured part, eliminating the need for multiple separate components and complex assembly procedures. This merging reduces device complexity while maintaining enhanced functionality through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)
