Image Processing System Job Request Confirmation Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing systems face issues with erroneous job execution due to simultaneous job requests from multiple terminals, leading to information leakage and decreased usability, as users may mistakenly assume their job requests have been accepted when they have not, especially when terminals are shared or used consecutively.
Innovation Solution
The image processing system employs a receiving unit to manage job requests and an accepting unit to display different execution instruction acceptance screens based on whether multiple job requests are received, providing confirmation information for overlapping requests to prevent errors while omitting it for single requests to improve usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the image processing apparatus accepts multiple job requests simultaneously, then the productivity increases, but the reliability decreases due to erroneous job execution and information leakage
Solution Approach 1:
The patent segments the job request handling process into distinct phases: request reception, confirmation display, and job execution. By introducing a confirmation phase between request reception and execution, the system maintains the ability to handle multiple requests while preventing erroneous executions through user verification at the confirmation stage.
Solution Approach 2:
The patent implements a feedback mechanism by displaying confirmation information (such as destination address and job details) to the user before job execution. This feedback loop allows users to verify the job parameters and correct any errors, thereby maintaining reliability while enabling simultaneous request handling.
2Reliability
If the image processing apparatus displays confirmation information for all job requests, then the reliability improves, but the ease of operation decreases due to increased interface complexity
Solution Approach 1:
The patent dynamically adjusts the interface behavior based on the job request context. Confirmation information is displayed only when necessary (e.g., for fax transmissions where destination verification is critical), while simpler interfaces are used for routine operations. This dynamic adaptation maintains reliability where needed without unnecessarily complicating the interface for all operations.
Solution Approach 2:
The patent applies different levels of confirmation requirements to different job types and scenarios. High-risk operations (such as fax transmissions to unverified destinations) require confirmation displays, while low-risk operations proceed without confirmation. This localized application of confirmation mechanisms maintains reliability for critical operations while preserving ease of operation for routine tasks.
3Reliability
If the image processing apparatus rejects duplicate job requests, then the reliability improves, but the productivity decreases due to lost opportunities for simultaneous processing
Solution Approach 1:
The patent uses feedback mechanisms to distinguish between intentional duplicate requests (which should be rejected) and unintentional duplicate requests resulting from simultaneous operations (which should be accepted). By displaying confirmation information and seeking user verification, the system can identify genuine duplicates and reject them while allowing simultaneous requests to proceed, thus maintaining both reliability and productivity.
Solution Approach 2:
The patent dynamically adjusts the acceptance criteria for job requests based on the current system state and user interactions. When confirmation information is displayed and verified, the system accepts the request even if similar requests are pending, allowing simultaneous processing. When unverified duplicate requests are detected, the system rejects them. This dynamic approach maintains reliability without unnecessarily reducing productivity.

AI summary
An image processing system that prevents erroneous job execution without significantly decreasing the usability includes receiving a request relating to a job, accepting a job execution instruction, and executing the job in response to acceptance of the execution instruction. If a plurality of requests relating to jobs is received, information for confirmation of the job is provided. If a single request relating to a job is received, information for confirmation of the job is not provided.
