Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reflective display technologies, such as E-INK or MARISOL, have not been effectively integrated with touch-based input devices and lack haptic feedback, dynamic adjustment to power states, and user customization, limiting their use in information handling devices.
Innovation Solution
Implementing a touchable control area with reflective display technology, capacitive touch sensing, and haptic feedback within information handling devices, allowing dynamic configuration and low power consumption by only drawing power when display contents change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reflective display technology is integrated with touch-based input devices, then user interaction capability is improved, but device complexity increases
Solution Approach 1:
The patent merges reflective display technology with touch-based input devices into a single integrated component. The display layer and touch sensing layer are combined in one device structure, allowing the same surface to provide both visual output and tactile input functionality, thereby improving user interaction capability while managing device complexity through integration.
Solution Approach 2:
The integrated device serves multiple functions simultaneously - it acts as both a display device and a touch input device. This multi-functionality allows the device to replace separate components (display + keyboard or touchscreen), enhancing adaptability and versatility while the unified structure helps control overall complexity.
2Illumination intensity
If reflective display is used continuously, then display visibility is maintained, but power consumption increases
Solution Approach 1:
The reflective display operates using periodic updates rather than continuous power consumption. The display contents are updated only when changes occur, and the reflective nature of the display technology allows the image to persist without continuous energy input, thereby maintaining visibility while significantly reducing power consumption compared to traditional illuminated displays.
3Ease of operation
If touch-based control area is made fully functional, then user control capability is improved, but manufacturing complexity increases
Solution Approach 1:
The touch-based control area is divided into distinct functional zones or segments that correspond to different input regions. This segmentation allows for modular manufacturing approaches where different areas can be optimized independently, simplifying the overall manufacturing process while maintaining full functional capability across the control surface.
