Protrusion Portion Prevents Display Contact in Receiving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for image forming apparatuses face challenges in accurately distinguishing between user input operations and near-field wireless communication interactions, particularly when a wireless communication device comes into proximity with the display, leading to unintended operations.
Innovation Solution
Incorporating a protrusion portion between the display and the communication unit, which is designed to facilitate near-field wireless communication while preventing accidental contact between the wireless communication device and the display, utilizing a light detecting unit to differentiate between user inputs and communication device interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication unit is disposed close to the display for near-field wireless communication, then communication functionality is improved, but unintended operations occur when a wireless communication device comes into proximity with the display
Solution Approach 1:
The user interface is segmented into distinct functional zones: a first region for touch operations on the display, and a second region for near-field wireless communication. This spatial segmentation allows the system to distinguish between touch input and wireless communication operations, preventing unintended operations while maintaining both functionalities.
Solution Approach 2:
Different regions of the user interface are assigned different functional qualities. The first region (display area) is optimized for touch sensitivity and visual output, while the second region (communication area) is optimized for electromagnetic field interaction. This local differentiation enables accurate detection of user intent based on location.
2Ease of operation
If the display surface is made flat and continuous for ease of operation, then user interface simplicity is improved, but accidental contact between wireless communication device and display cannot be prevented
Solution Approach 1:
A protrusion portion is introduced as an intermediary element between the display and the communication unit. This physical structure serves as a spatial mediator that creates a natural barrier, guiding wireless communication devices to interact with the communication unit rather than the display, thus preventing accidental contact while maintaining overall interface simplicity.
3Reliability
If hardware keys are used for input operations, then operation reliability is improved, but device complexity increases
Solution Approach 1:
The display surface serves multiple functions: it acts as both the visual output interface and the touch input interface. By making the display itself operable through touch, the system eliminates the need for separate hardware keys, reducing structural complexity while maintaining reliable operation through touch sensitivity detection.
Data Source
AI summary
A receiving device includes a display, a communication unit, and a protrusion portion. The display displays an image and receives an operation corresponding to the image in such a manner that a user comes into contact with the image. The communication unit communicates with a wireless communication apparatus performing near-field wireless communication. The protrusion portion is disposed at least between the display and the communication unit and protrudes from a surface on which the display is provided.
