Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a haptic feedback apparatus is designed to transfer tactile sensation to a user's finger, then the user can intuitively recognize power applied to a robot or virtual object, but the apparatus becomes complex requiring multiple actuators and controllers to achieve 3D physical movement
Solution Approach 1:
The power feedback portion is divided into multiple independent actuator systems (first actuators for vertical movement, second actuators for horizontal movement) that can be controlled separately. This segmentation allows each actuator to handle a specific degree of freedom, making the complex 3D movement task manageable through modular control while maintaining effective tactile feedback
Solution Approach 2:
The power feedback portion acts as an intermediary element between the sensor that detects power applied to virtual objects and the user's finger. This intermediary converts sensed power data into physical movements that replicate tactile sensations, effectively bridging the gap between virtual interaction and physical sensation without requiring direct complex mechanisms at the user interface
2Ease of operation
If the power feedback portion is moved in multiple directions to express sensed power accurately, then intuitive control is enhanced, but the precision of movement control decreases due to the complexity of coordinating multiple actuators
Solution Approach 1:
The system dynamically adjusts the movement of the power feedback portion based on real-time sensed power data. The controllers continuously modify the position and movement of each actuator to accurately replicate the tactile sensations being experienced, allowing the system to adapt its complexity to the specific interaction requirements rather than maintaining fixed precision mechanisms
Solution Approach 2:
The sensor provides continuous feedback about the power applied to virtual objects, which is then processed by controllers that adjust the power feedback portion's movement in real-time. This feedback loop ensures that the physical movement accurately reflects the virtual interaction, maintaining precision through active control rather than passive mechanical precision
3Reliability
If actuators are used to move the power feedback portion, then tactile sensation can be transferred to the user, but the device requires significant energy to operate multiple actuators and controllers
Solution Approach 1:
The power feedback portion serves multiple functions simultaneously: it is both the actuator that moves to create tactile feedback and the contact surface that transfers force to the user's finger. This multi-functionality reduces the need for separate energy-consuming components, as the same structure performs both movement generation and force transmission, thereby reducing overall energy consumption while maintaining effective tactile feedback
