Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a virtual machining simulator is created to provide accessible training, then training accessibility and cost are improved, but haptic feedback accuracy deteriorates
Solution Approach 1:
The patent replaces complex mechanical haptic feedback systems with an electrical motor system controlled by a processor. The motor receives voltage input from the processor based on user inputs and database comparisons, converting electrical signals into haptic responses. This substitution maintains training accessibility while achieving sufficient haptic feedback accuracy through electronic control rather than complex mechanical mechanisms.
Solution Approach 2:
The patent dynamically adjusts haptic feedback parameters by comparing user inputs against ideal values stored in a database. The processor calculates the difference between actual and ideal inputs, then adjusts motor voltage accordingly to provide proportional haptic feedback. This parameter-based approach enables accurate haptic responses without requiring expensive mechanical systems, making training accessible while maintaining precision.
2Reliability
If haptic feedback is added to virtual simulator to improve training effectiveness, then training quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical haptic feedback systems with a streamlined electrical motor system. The motor is controlled by a processor that receives user inputs, compares them to database values, and generates appropriate voltage signals. This electrical approach achieves reliable training effectiveness while minimizing device complexity compared to traditional mechanical haptic systems.
Solution Approach 2:
The patent implements a feedback loop where user inputs are continuously compared against ideal values in the database, and the processor adjusts motor voltage based on the difference. This feedback mechanism provides reliable haptic guidance for skill development without requiring complex mechanical systems, maintaining training effectiveness while controlling device complexity.
