Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held computer mouse or joystick is used, then device portability is improved, but haptic feedback capability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical input devices (mouse, joystick) with a haptic hand controller that uses electromechanical actuators to generate tactile feedback. The system substitutes mechanical sliding or twisting motions with haptic actuation, enabling natural hand gestures to control digital interfaces while providing immersive tactile sensations through the controller's contact points with the hand.
Solution Approach 2:
The hand controller integrates multiple functions into a single device: it serves as both an input device for controlling digital interfaces and an output device for delivering haptic feedback. The controller simultaneously measures hand motions, translates them to digital commands, and provides tactile feedback, eliminating the need for separate input and feedback devices.
2Device complexity
If traditional computer interfaces are used, then system simplicity is improved, but interaction dimensionality deteriorates
Solution Approach 1:
The patent adds haptic feedback as a new dimension to traditional two-dimensional computer interfaces. By incorporating tactile sensations that can be felt through the hand and fingertips, the system transitions from planar interaction to multi-dimensional interaction, enabling users to perceive depth, texture, and spatial relationships in virtual environments through tactile cues.
Solution Approach 2:
The hand controller acts as an intermediary between the user's hand and the digital interface. It captures hand motions and gestures, translates them into digital commands, and simultaneously delivers haptic feedback to the hand. This intermediary device bridges the gap between physical hand movements and virtual digital interactions, enabling natural multi-dimensional control.
3Ease of operation
If haptic hand controller is designed to clasp onto hand, then interaction naturalness is improved, but device complexity increases
Solution Approach 1:
The controller is divided into multiple functional segments: a hand-clasping structural component for natural engagement, sensor arrays for measuring hand motions and forces, actuator modules for delivering haptic feedback at specific contact points, and processing electronics. This segmentation allows each component to be optimized independently while working together to achieve natural hand interaction.
Solution Approach 2:
The controller incorporates dynamic elements including adjustable spring tension in the clasping mechanism, real-time measurement of hand motions and applied forces, and adaptive haptic feedback that responds to user interactions. The system dynamically adjusts its response based on detected hand gestures and contact forces, enabling natural and intuitive control.
