Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional composite scanning systems can only perform a single operation in a specific state, leading to low capability setting efficiency, particularly in composite scanning devices where printing capability settings cannot be implemented until after image processing, resulting in inefficient user interaction.
Innovation Solution
A composite scanning system comprising an application module for performing initial capability settings, a configuration module for adjusting settings based on processing results, and a Data Source for managing communication, allowing for automatic capability setting adjustments during the Transfer Ready state, enabling both scanning and printing operations within the TWAIN protocol.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the composite scanning device follows the TWAIN protocol strictly with single operation per state, then the protocol compatibility is ensured, but the capability setting efficiency deteriorates
Solution Approach 1:
The patent applies the dynamics principle by enabling the Data Source to transition from a static single-operation-per-state model to a dynamic multi-operation model. The Data Source is configured to perform multiple operations (scanning, printing, copying) within the same Transfer Ready state, allowing capability settings to be adjusted flexibly based on processing results while maintaining TWAIN protocol compatibility through structured state management.
Solution Approach 2:
The patent utilizes parameter changes by modifying the operational parameters of the Data Source within the TWAIN protocol framework. The system changes the state parameters to allow multiple operations in the Transfer Ready state, and adjusts capability settings dynamically based on image processing results, thereby improving efficiency without violating protocol requirements.
2Stability of the object's composition
If printing capability setting is performed after image processing, then the workflow sequence is maintained, but the user interaction efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by configuring the Data Source to perform printing capability settings in advance during the Transfer Ready state, before the image processing is completed. The system prepares printing parameters and settings proactively, allowing users to review and adjust capabilities while the image is being processed, thereby improving interaction efficiency without disrupting the overall workflow sequence.
Solution Approach 2:
The patent implements feedback by enabling the system to adjust printing capability settings based on the image processing results. The Data Source receives feedback about the processed image characteristics and automatically modifies printing parameters accordingly, creating an interactive loop that improves user experience while maintaining workflow stability.
3Device complexity
If only single operation is implemented per TWAIN state, then the protocol implementation is simple, but the operational versatility deteriorates
Solution Approach 1:
The patent applies universality by configuring the Data Source to perform multiple operations (scanning, printing, copying) within the same Transfer Ready state. The system is designed to handle diverse operational modes through a unified state management approach, enabling a single Data Source to serve multiple functions without significantly increasing protocol implementation complexity.
Solution Approach 2:
The patent utilizes dynamics by enabling the Data Source to transition between different operational modes flexibly within the Transfer Ready state. The system dynamically adjusts its behavior based on user needs and processing results, allowing scanning, printing, and copying operations to be performed in sequence or combination without requiring separate protocol states for each operation.
