Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in setting up communication between mobile terminals and printers, particularly in temporary usage scenarios, as they need to manually select the printer as the destination for print instructions, which can be burdensome.
Innovation Solution
Incorporating a visible light communication system where the printer transmits designation information using an imaging light unit, allowing the mobile terminal to receive this information and establish wireless communication without manual selection, enabling seamless print instruction transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of printer destination is required, then communication setup can be precise and controlled, but user operation becomes complex and time-consuming
Solution Approach 1:
The mobile terminal performs automatic printer selection by itself through visible light communication. The terminal captures light signals from the printer containing designation information, automatically extracts printer identification, and establishes wireless connection without requiring user intervention in the selection process, thus resolving the contradiction between ease of operation and time consumption
Solution Approach 2:
The printer preliminarily transmits its designation information through visible light communication before the actual print instruction is sent. This preliminary action allows the mobile terminal to obtain and store printer identification information in advance, eliminating the need for manual selection at the time of printing and reducing both operational complexity and time
2Extent of automation
If visible light communication is used for designation information transfer, then communication setup becomes automatic and convenient, but additional hardware components are required
Solution Approach 1:
The visible light communication system serves multiple functions: it transmits printer designation information for automatic selection, provides visual feedback for connection status, and enables wireless communication establishment. By making the light communication system multi-functional, the patent reduces the need for separate dedicated components, thereby managing device complexity while achieving high automation
Solution Approach 2:
Visible light acts as an intermediary carrier for transmitting printer designation information from the printer to the mobile terminal. This optical intermediary enables automatic identification and connection establishment without requiring complex direct wireless communication protocols between the terminal and printer, thus achieving automation while controlling system complexity

AI summary
A printer includes an imaging unit, an imaging light unit, a transmitter, and a receiver. The transmitter transmits designation information via visible light communication by using the imaging light unit. The designation information is information for designating the printer as a destination of wireless communication. The receiver receives a print instruction from a mobile information processing apparatus via the wireless communication in accordance with the designation information.
