Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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.
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
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.
