Methods and apparatus for designing animatronics units using animation data to determine control signals, which are applied to physically control the units, allowing for a software simulation to estimate and output the behavior of the animatronics, enabling more faithful representation of animated characters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If animatronics units are custom-built for specific purposes, then they can be tailored to specific performance requirements, but they cannot accurately represent computer-generated character animations because animation data has not been utilized for their construction or control

Engineering Contradiction:
Improveaccuracy of representing CG character animationsVSAvoidcustom-building process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by creating a software simulation model of the animatronics unit before physical construction. Animation data from CG characters is used to pre-determine control signals and predict behavior in virtual space, allowing design optimization before committing to expensive custom physical construction. This resolves the contradiction by enabling accurate representation planning without immediately requiring complex custom-building.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating a virtual software simulation that replicates the animatronics unit's expected behavior. This digital twin is driven by animation data to copy the movements and behaviors of CG characters, allowing accurate representation to be achieved and tested virtually before physical implementation, thereby reducing the risk of custom-building failures.

Inventive Principle:
Principle #26Copying

2Reliability

If animation data from CG characters is used to control animatronics units, then faithful representation of animated characters is achieved, but new challenges arise in converting animation data into physical control signals

Engineering Contradiction:
Improvefaithfulness of character representationVSAvoidcontrol signal conversion process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary software simulation that acts as a bridge between animation data and physical animatronics control. The simulation converts animation data into control signals in a virtual environment, allowing the complex conversion process to be tested and optimized before applying it to physical units, thereby achieving reliable representation while managing conversion complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical control conversion with a software-based simulation approach. Instead of directly converting animation data to physical control signals through complex mechanical systems, the patent uses software to simulate and predict behavior, substituting the mechanical conversion process with computational modeling that can be more easily adjusted and optimized.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If software simulation is used to estimate animatronics behavior before construction, then design accuracy is improved, but additional time and computational resources are required

Engineering Contradiction:
Improvedesign accuracy of animatronics unitVSAvoidsimulation and testing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing behavior estimation through software simulation before physical construction begins. This allows design accuracy to be improved upfront by identifying and correcting issues in the virtual model, preventing costly rework during physical construction and reducing overall development time despite the initial simulation investment.

Inventive Principle:
Principle #10Preliminary action
