Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional 2D input devices (keyboard, mouse) are used for 3D computer modeling applications, then device simplicity is maintained, but user efficiency and ease of operation deteriorate due to inability to provide required range of motion
Solution Approach 1:
The housing transforms between different form factors (spherical, cylindrical, conical, pyramidal, flat) to dynamically adapt to different input modes. This dynamic shape changing allows the device to optimize its geometry for specific 3D manipulation tasks, resolving the contradiction between maintaining simple device design and achieving high user efficiency in 3D applications
Solution Approach 2:
A single interface device performs multiple functions by transforming between different form factors, each corresponding to different input modes (translational, rotational, combined). This multi-functionality eliminates the need for multiple specialized devices while maintaining ease of operation across various 3D modeling tasks
2Ease of operation
If special input devices are developed for 3D computer applications, then ease of operation improves, but device complexity increases and range of motion may be limited
Solution Approach 1:
The transformation assembly enables the housing to change its form factor dynamically, allowing the device to adapt its complexity to the specific task at hand. When rotational input is needed, the spherical form factor is activated; for translational input, the flat form factor is used. This dynamic adaptation resolves the contradiction by only activating the necessary complexity for each input mode
3Adaptability or versatility
If housing form factor is fixed, then manufacturing simplicity is maintained, but adaptability to different input modes deteriorates
Solution Approach 1:
The housing is divided into multiple segments or components that can be reconfigured through the transformation assembly. This segmentation allows the device to achieve multiple form factors while maintaining manufacturing feasibility through modular construction, resolving the contradiction between adaptability and manufacturing simplicity
Solution Approach 2:
The transformation assembly provides a mechanical means to change the housing form factor between different input modes. This dynamic reconfigurability achieves high adaptability to different 3D input requirements while using standardized manufacturing processes for each form factor configuration
