Electronic Display Protrusion Unit Tactile Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices are limited to two-dimensional information display and rely on visual recognition, lacking the ability to provide tactile or three-dimensional recognition of objects.
Innovation Solution
An electronic display device with a protrusion unit that generates a display via a protrusion mechanism, driven by a driving unit, which can produce tactile and visual displays based on recognition signals, allowing for both tactile and visual recognition of objects through comparison with stored display information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional display devices use two-dimensional visual display, then the device complexity is low, but the measurement precision of object recognition is insufficient
Solution Approach 1:
The patent combines multiple display modalities (visual display, tactile display through protrusions, and audio output) into a single integrated display device. The protrusion unit is integrated with the display screen, allowing simultaneous visual and tactile feedback from the same device structure, thereby improving recognition precision without proportionally increasing complexity
Solution Approach 2:
The patent transitions from two-dimensional visual display to three-dimensional tactile display by generating physical protrusions that extend from the display surface. This dimensional change enables users to perceive object information through touch in addition to vision, significantly enhancing measurement precision for object recognition
2Loss of information
If display devices provide only visual information, then the ease of operation is high, but the loss of information is significant
Solution Approach 1:
The display device is designed to serve multiple functions simultaneously: visual display, tactile feedback through protrusions, and audio output. This multi-functionality ensures that comprehensive object information is conveyed through multiple channels, reducing information loss while maintaining ease of operation through a unified interface
3Measurement precision
If the protrusion unit generates tactile display, then the measurement precision of object recognition is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a driving unit as an intermediary component between the control system and the protrusion unit. This driving unit manages the complex task of generating and controlling multiple protrusions, thereby improving tactile recognition precision while isolating the complexity within a dedicated subsystem rather than distributing it throughout the entire device
