Dual Wireless Image Recording System Communication Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing image recording system burdens the communication process between mobile terminals and image recording apparatuses due to frequent acquisitions of path information using lower-capacity communication channels, leading to increased communication load.
Innovation Solution
The system employs dual wireless communication channels - a short-range communication for setting up connections and a higher-capacity channel for data transfer, allowing the mobile terminal to store image data and specific information, and the image recording apparatus to record data using either channel based on availability, thereby reducing the communication burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If path information is acquired frequently using the second communication function (higher transmission rate), then the image data transfer speed is improved, but the communication burden between mobile terminal and image recording apparatus increases
Solution Approach 1:
The patent divides the communication process into two distinct phases: (1) path information acquisition phase using the first communication function (lower rate, less burden), and (2) image data transfer phase using the second communication function (higher rate, faster transfer). This segmentation allows each communication function to be optimized for its specific purpose, reducing overall communication burden while maintaining high transfer speeds when needed.
Solution Approach 2:
The patent performs path information acquisition in advance using the first communication function before the actual image data transfer. By establishing the communication path and exchanging necessary routing information beforehand, the system prepares the higher-capacity second communication function for efficient data transfer without incurring repeated setup overhead during the transfer process.
2Loss of energy
If the first communication function (lower transmission rate) is used for all data communication, then the communication burden is reduced, but the image data transfer efficiency decreases
Solution Approach 1:
The patent segments the data communication tasks based on their requirements: control and path information (small data volume, frequent exchanges) are handled by the first communication function to reduce burden, while bulk image data transfer (large data volume, less frequent) utilizes the second communication function for high efficiency. This task-based segmentation optimizes both communication burden and transfer efficiency.
Solution Approach 2:
The patent dynamically changes the transmission rate parameter by selecting different communication functions based on the data type and transfer requirements. For path information, the lower rate of the first function is sufficient and less burdensome; for image data, the higher rate of the second function maximizes efficiency. This parameter adaptation resolves the contradiction between burden and efficiency.
3Adaptability or versatility
If dual communication functions are implemented, then communication flexibility and efficiency are improved, but the device complexity increases
Solution Approach 1:
The patent implements a control mechanism that universally manages two communication functions through a single control unit. This control unit intelligently selects and coordinates the first and second communication functions based on communication requirements, providing multi-functionality without requiring separate control systems for each function. The universal control approach maintains flexibility while minimizing the increase in overall system complexity.

AI summary
When first wireless communication is established, a mobile terminal sends image data specific information for specifying a set of image data to an image recording apparatus by the first wireless communication. When a set of image data associated with the image data specific information corresponding to the image data specific information received by the first wireless communication is stored, an image recording apparatus records an image corresponding to the stored set of image data onto a recording medium. When such a set of image data is not stored, the image recording apparatus receives the set of image data from the mobile terminal by the second wireless communication and records an image corresponding to the received set of image data onto the recording medium. The image recording apparatus then stores the received set of image data and the image data specific information in association with each other.
