Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If object texture images are translated into tactile features using a generative model, then realistic tactile sensations can be generated, but the system complexity increases due to the need for encoding units, verification units, and control units
Solution Approach 1:
The system is divided into distinct functional modules: an encoding unit that processes texture images into latent representations, a generative model that infers tactile features from these representations, and a verification unit that ensures feature accuracy. This segmentation allows each component to be optimized independently while maintaining overall system reliability for generating realistic tactile sensations.
Solution Approach 2:
The encoding unit acts as an intermediary that translates visual texture information into a latent space representation that the generative model can process. This intermediary layer enables the system to bridge the gap between visual input and tactile output without requiring direct complex mapping, thereby managing system complexity while maintaining tactile realism.
2Measurement precision
If texture tactile feature information is verified against predetermined conditions, then the accuracy of tactile feedback is improved, but the processing time increases
Solution Approach 1:
The verification unit checks whether inferred tactile features meet predetermined conditions before final output. By performing this verification as a preliminary check in the processing pipeline, the system ensures accuracy requirements are met while allowing the main generative process to continue efficiently, minimizing overall processing time and feedback delay.
3Manufacturing precision
If a generative model is trained with multiple texture image samples under parameter constraints, then the quality of inferred tactile features is improved, but the training time and computational resources increase
Solution Approach 1:
The training process uses parameter description information and predetermined constraints to guide the generative model's learning. By carefully selecting and constraining the parameters during training on multiple texture image samples, the system achieves high-quality tactile feature inference while managing training computational requirements through focused parameter optimization rather than exhaustive training.
