Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a handheld digital drawing device projects output onto external surfaces, then the display area and interactivity are improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (digital drawing, sensing, projection, and display environment generation) into a single handheld device. The determining component integrates processing of user inputs, sensing component data, and projection output generation, merging what would traditionally be separate systems into one unified device that can project interactive content onto external surfaces.
Solution Approach 2:
The device is designed to perform multiple functions: receiving user inputs via screen, sensing device orientation and acceleration, determining appropriate output, projecting onto external surfaces, and generating display environments. This multi-functional approach allows one device to replace multiple separate tools while expanding the effective display area to external surfaces.
2Adaptability or versatility
If the device adapts projection to orientation and movement, then the adaptability is improved, but the measurement precision requirements increase
Solution Approach 1:
The sensing component continuously monitors device orientation and acceleration, providing real-time feedback to the determining component. This feedback loop enables the system to automatically adjust the projected output and display environment based on the device's physical state, improving adaptability while managing measurement precision requirements through integrated processing.
Solution Approach 2:
The projection system is designed to be dynamic, automatically adjusting the projected content and display environment based on real-time sensing data. The device transitions from a static projection system to one that dynamically adapts to user movement and orientation changes, enhancing versatility while managing measurement requirements through integrated control.
