Voice Printing Server Time-Adaptive Content Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printing systems using smart speakers for cloud printing services lack the ability to select appropriate content for printing based on time-dependent probabilities, often resulting in inappropriate content being printed when multiple contents are available without proper names, leading to user dissatisfaction.
Innovation Solution
A printing system that includes a server and a printing apparatus connected via a network, where the server acquires voice instructions, selects content from a group based on time-dependent probabilities stored in a weight table, and transmits print data to the printing apparatus for execution, ensuring that content is printed according to its designated time-dependent probabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the server randomly selects content from a content group when multiple contents are available without proper names, then the printing system can execute printing, but the content printed may not be appropriate to the time of the print instruction
Solution Approach 1:
The patent applies dynamics by making the content selection process adaptive to time changes. The server dynamically adjusts selection probabilities based on the current time, selecting from time-dependent contents with different probabilities at different times. This resolves the contradiction by maintaining easy voice-based printing execution while ensuring content appropriateness through time-adaptive probability-based selection.
Solution Approach 2:
The patent changes the parameter of selection probability based on time. Each time-dependent content is assigned a probability that varies according to the time of print instruction. This allows the system to maintain simple voice-based operation while improving content appropriateness by adjusting selection parameters (probabilities) according to temporal context.
2Reliability
If the server selects content based on time-dependent probabilities, then the content printed is appropriate to the time, but the system complexity increases due to probability management
Solution Approach 1:
The patent applies self-service by enabling the server to automatically manage time-dependent selection probabilities without requiring external intervention or complex user input. The server independently determines appropriate probabilities based on time information and executes selection accordingly, resolving the contradiction by automating the probability management process and minimizing system complexity.
Solution Approach 2:
The patent introduces time information as an intermediary element that mediates between the print instruction and content selection. Rather than directly managing complex selection logic, the server uses time as a mediator to determine selection probabilities, simplifying the selection mechanism while ensuring content appropriateness.
3Reliability
If the server uses time-dependent probability selection, then user satisfaction improves, but the processing time increases due to probability calculations
Solution Approach 1:
The patent applies preliminary action by pre-establishing time-dependent probability settings for different contents. The server prepares selection probabilities in advance based on time information, allowing rapid selection execution when a print instruction is received. This resolves the contradiction by performing probability setup beforehand, reducing actual selection processing time while maintaining user satisfaction through appropriate content selection.

AI summary
A server of a printing system includes a print instruction acquisition unit acquiring a print instruction of a content contained in a content group by a voice from a voice mediation device, a selection unit selecting the content to be printed from the content group according to the print instruction, and a transmission unit transmitting print data for printing of the selected content to a printing apparatus of the printing system, wherein the content group contains a plurality of time-dependent contents having different probabilities for selection according to a time when the print instruction is acquired, the selection unit selects the content to be printed from the content group so that each of the plurality of time-dependent contents is selected with the probability according to the time when the print instruction is acquired. The printing apparatus receives the print data and executes printing according to the print data.
