Media Processing Device Web Browser Control via Markup Language
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media processing devices with reading units are limited in control methods, relying primarily on host computer control, which restricts their versatility and functionality.
Innovation Solution
Implementing a media processing device with a reading unit, communication unit, and control unit that uses markup language for controlling the reading unit, allowing control via web browsers and enabling operation without a device driver, thus expanding control methods and device compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a media processing device is controlled only by a host computer through device drivers, then the control method is simple and reliable, but the device versatility and adaptability are limited
Solution Approach 1:
The patent implements multiple control interfaces (host computer control via device driver and web browser control via markup language) within a single media processing device. The control unit can process both traditional device driver commands and markup language instructions, enabling the device to function in multiple control modes without requiring separate systems for each method.
Solution Approach 2:
The patent introduces a communication unit that acts as an intermediary between the web browser and the control unit. This communication unit receives markup language control data from the web browser and translates it into commands that the control unit can execute, thereby mediating between the new web-based control method and the existing device control architecture.
2Ease of operation
If a device driver is required for controlling the reading unit, then the control is reliable and precise, but the device cannot operate independently without a host computer
Solution Approach 1:
The patent enables the media processing device to serve itself by accepting control commands directly from a web browser without requiring a host computer. The control unit processes markup language instructions and executes reading operations independently, allowing the device to function autonomously while maintaining its existing host computer integration capabilities.
3Adaptability or versatility
If markup language control data is used to control the reading unit, then web browser compatibility is improved, but the control precision and reliability may be reduced
Solution Approach 1:
The patent transforms the control interface parameters from proprietary device driver commands to standardized markup language instructions. This parameter change enables web browser compatibility while the control unit maintains precise control over the reading unit by translating markup language commands into precise control actions.
