Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of executable functions on portable terminals like smartphones increases, the amount of information displayed on the screen also increases, leading to degraded operability in interactions with printers.
Innovation Solution
A printing system comprising a printer and a terminal that can wirelessly communicate, where the printer includes a movement detection unit and a control signal transmission unit to adjust the operation screens displayed on the terminal based on the printer's movement, improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of executable functions on the portable terminal is increased, then the functionality of the printing system is improved, but the amount of information displayed on the terminal screen increases leading to degraded operability
Solution Approach 1:
The patent applies dynamics by making the display screen adaptable and changeable based on the printer's movement state. The terminal dynamically adjusts which operation screens are displayed according to whether the printer is in horizontal or vertical orientation, allowing the interface to evolve based on physical conditions rather than being static. This resolves the contradiction by enabling multiple functions to be accessed through context-appropriate displays rather than overwhelming the user with all functions simultaneously
Solution Approach 2:
The patent changes the parameter of display content based on the printer's movement detection. When the printer detects a change in orientation (horizontal vs vertical), it transmits control signals to the terminal to switch between different operation screens. This parameter change approach allows the system to maintain full functionality while presenting only relevant operations at any given time, thus preserving operability
2Adaptability or versatility
If multiple operation screens are displayed on the terminal, then more functions are accessible, but the complexity of the interface increases making operation more difficult
Solution Approach 1:
The patent segments the operation interface into multiple distinct screens that are displayed based on the printer's movement state. Instead of presenting all functions on a single complex screen, the system divides operations into different categories (e.g., printing functions when horizontal, scanning functions when vertical) and displays them on separate screens. This segmentation reduces the cognitive load on users while maintaining comprehensive functionality across different contexts
3Ease of operation
If the printer automatically switches operation modes based on movement detection, then ease of operation is improved, but the complexity of the control system increases
Solution Approach 1:
The printer performs self-service by automatically detecting its own movement state and autonomously determining which operation mode should be displayed on the terminal. The movement detection unit monitors the printer's orientation, and based on this self-detected information, the control unit automatically transmits appropriate control signals to the terminal without requiring manual user configuration. This self-service capability simplifies user operation while the added complexity is confined to the automated detection and control mechanisms

AI summary
A printing system includes a printer and a terminal capable of wirelessly communicating with each other. The printer include a portable printer main body, a movement detection unit that detects a movement of the printer main body, and a first processor configured to transmit a first control signal to the terminal in a case where a first movement is detected by the movement detection unit, and transmit a second control signal to the terminal in a case where a second movement is detected by the movement detection unit. The terminal includes a display unit, a second processor configured to receive the control signals from the printer; and display a first operation screen on the display unit in a case where the first control signal is received, and display a second operation screen on the display unit in a case where the second control signal is received.
