Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional controllers (mouse, keyboard) are used for positioning sound images, then the system is simple to operate, but the depth and precision of control in three-dimensional space is limited
Solution Approach 1:
The patent replaces traditional mechanical input devices (mouse, keyboard) with a three-dimensional motion sensing input device that uses optical fields and gesture recognition. This substitution enables precise three-dimensional positioning of sound images by capturing natural hand movements and gestures, transforming mechanical control into spatially-aware gesture-based control while maintaining ease of operation through intuitive hand motions.
2Adaptability or versatility
If more features and functions are added to the digital audio workstation, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal gesture control system where a single three-dimensional motion sensing input device can control multiple functions and features within the digital audio workstation. Pre-defined gestures map to various operations including sound image positioning, parameter adjustment, and tool selection, allowing one device to perform multiple functions without increasing physical complexity.
Solution Approach 2:
The patent adds a third spatial dimension to the control interface by using gesture recognition in three-dimensional space. This dimensional expansion allows users to interact with sound images and controls in a more natural and intuitive manner, accommodating increased functionality without proportionally increasing operational complexity.
3Loss of information
If traditional two-dimensional controllers are used, then the device complexity is low, but the sense of depth for three-dimensional positioning is insufficient
Solution Approach 1:
The patent replaces two-dimensional mechanical controllers with a three-dimensional motion sensing system that uses optical fields and gesture recognition. This substitution restores depth perception by capturing the spatial coordinates and movement trajectories of hand gestures, providing intuitive depth cues for positioning sound images in three-dimensional space without requiring complex mechanical structures.
