Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If motion mechanisms are added to printed characters, then expressiveness and storytelling possibilities are enhanced, but device complexity increases

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

Solution Approach 1:

The character is divided into multiple independently printable components (body parts, limbs, accessories) that can be manufactured separately and assembled later. This segmentation allows complex motion-capable characters to be created without requiring the entire assembly to be printed as one complex piece, thereby managing device complexity while maintaining expressiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system enables printed characters to transition from static to dynamic states by incorporating motion mechanisms such as linkages, motors, and propagation mechanisms. These dynamic elements allow characters to perform periodic motions and expressive movements, directly enhancing adaptability and versatility.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If visual design tools are provided to users, then creative vision expression is improved, but technical difficulties in character creation remain

Engineering Contradiction:
Improveease of useVSAvoidtechnical difficulties
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The software application serves as an intermediary between the user's creative vision and the complex mechanical character creation process. It provides visual design tools that abstract away technical complexities, allowing users to define desired motions and poses without needing to understand the underlying mechanical principles of linkages, motors, and propagation mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system automatically computes mechanical parameters and generates linkage designs based on user-defined motion requirements. This self-service capability eliminates the need for users to manually calculate complex mechanical parameters, thereby reducing technical barriers while maintaining ease of use.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If motion parameters are precisely controlled, then periodic motion accuracy is improved, but computational complexity increases

Engineering Contradiction:
Improvemotion accuracyVSAvoidcomputational complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The software computes and determines all mechanical parameters (linkage lengths, motor positions, propagation mechanism configurations) before the actual character creation and printing process. This preliminary computation ensures that motion accuracy requirements are met while avoiding the need for complex real-time calculations during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system transforms user-defined motion requirements into specific mechanical parameters through automated computation. By changing parameters from abstract motion descriptions to concrete mechanical dimensions, the system achieves precise periodic motion control while managing computational complexity through pre-processing.

Inventive Principle:
Principle #35Parameter changes

AI summary

There are provided an interactive design system and method for character crafting. An example system includes a memory storing a machine software application and a processor configured to execute the machine software application to receive a plurality of components for a character, the plurality of components including at least a first component and a second component, receive a movement for the character, the movement including a first pose for the character and a second pose for the character, calculate a linkage for the first component and the second component based on the movement, and generate an updated character by connecting the second component to the first component using the linkage. The linkage may include at least one of a connector, a trimmer, and a propagation mechanism.
