Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If real-time computing is used to generate 3D model in real time, then the virtual character motion can be generated dynamically, but the computing resources required increase substantially
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing multiple sets of 3D mesh data corresponding to different mouth shapes and facial expressions in a database. Instead of computing 3D models in real-time during playback, the system retrieves pre-computed mesh data based on voice recognition results, significantly reducing computing resource requirements while maintaining dynamic motion generation capability.
2Adaptability or versatility
If real-time computing is used to generate 3D model, then the virtual character can respond dynamically to input, but the production cost increases substantially
Solution Approach 1:
The patent reduces production cost by performing 3D model generation work in advance and storing the results. The pre-computed 3D mesh data is retrieved during playback based on voice recognition, eliminating the need for expensive real-time computing hardware and reducing overall production costs while maintaining dynamic response capability.
Solution Approach 2:
The patent uses copying by storing multiple pre-generated 3D mesh models in a database that can be quickly retrieved and applied. Instead of generating unique 3D models in real-time, the system selects and applies appropriate pre-computed mesh copies from the database based on voice recognition results, reducing both computing costs and production expenses.
3Use of energy by moving object
If low frame rate is used due to insufficient hardware performance, then the computing load is reduced, but the motion of 3D model becomes inconsistent and image quality deteriorates
Solution Approach 1:
The patent ensures motion consistency by pre-generating 3D mesh data for various mouth shapes and facial expressions at appropriate frame rates and storing them in the database. During playback, the system retrieves the corresponding pre-computed mesh data based on voice recognition, ensuring smooth and consistent motion without requiring high computing load during real-time operation.
4Adaptability or versatility
If complex algorithms are used for real-time 3D model generation, then the virtual character motion can be generated dynamically, but the production cost increases
Solution Approach 1:
The patent reduces algorithm complexity by performing complex 3D model generation algorithms in advance during the production phase and storing the results. During playback, the system only needs to retrieve pre-computed mesh data based on simple voice recognition, significantly reducing the complexity of algorithms required during real-time operation while maintaining dynamic generation capability.
