Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods are used to reproduce face models and expressions for each different role, then the face design requirements for diverse robot roles can be met, but the process becomes complicated and costly
Solution Approach 1:
The face model is segmented into multiple independent components including base face models, facial feature objects (eyes, eyebrows, nose, mouth), and expression objects. Each component can be independently selected and configured to create different face designs for various robot roles, avoiding the need to recreate entire face models for each role.
Solution Approach 2:
A universal set of facial feature objects and expression objects is created that can be applied across multiple base face models. These reusable components serve multiple functions and can be combined in different configurations to meet diverse face design requirements for different robot roles, reducing overall system complexity.
2Adaptability or versatility
If conventional methods are used to reproduce face models and expressions for each different role, then the face design requirements for diverse robot roles can be met, but the process becomes time-consuming
Solution Approach 1:
Base face models, facial feature objects, and expression objects are pre-created and stored in a library before actual model building. This preliminary preparation allows for rapid assembly of custom face models by simply selecting and combining pre-existing components, significantly reducing the time required to create face models for different robot roles.
Solution Approach 2:
Instead of recreating face models from scratch for each role, the system uses copying and recombination of existing base face models and facial feature objects. This allows rapid duplication and adaptation of proven face model components to meet new design requirements, dramatically reducing model building time.
3Manufacturing precision
If multiple two-dimensional facial feature animation objects and three-dimensional facial feature animation objects are integrated, then the delicacy and vividness of the three-dimensional face model are improved, but the integration process becomes more complex
Solution Approach 1:
The system merges two-dimensional facial feature animation objects (providing detailed texture and expression) with three-dimensional facial feature animation objects (providing spatial structure and depth) into a unified face model. This combination leverages the strengths of both 2D and 3D representations to achieve high delicacy and vividness while managing integration complexity through standardized object interfaces.
