Scanner Controller Key Enable Logic for Push Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scanners may fail to perform a push-scan operation if the destination for transmitting scan data is not registered or has been deleted, leading to user inconvenience as the operation key for 'Scan to Mobile' is not enabled, preventing the transmission of scan data.
Innovation Solution
The scanner includes a controller that stores destination information in memory and enables or disables the operation key based on the presence of stored destination information, ensuring that scan data is only transmitted when a valid destination is registered, thereby preventing unauthorized data transmission and enhancing user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation key is enabled regardless of destination registration status, then user convenience is improved, but data security and proper function execution are worsened due to failed transmissions
Solution Approach 1:
The controller performs preliminary action by checking whether destination information is stored in memory before enabling the operation key. This advance verification ensures that the transmission function is only activated when a valid destination is available, preventing failed transmissions while maintaining user convenience.
2Reliability
If the operation key is disabled when no destination is registered, then data security is improved, but ease of operation is worsened due to restricted functionality
Solution Approach 1:
The system implements feedback by continuously monitoring the storage status of destination information in memory and dynamically adjusting the operation key state accordingly. When destination information is present, the key is enabled; when absent, it is disabled. This feedback mechanism ensures reliable data transmission while maintaining operational convenience through automatic state adjustment.
3Adaptability or versatility
If destination information is stored in memory, then transmission capability is improved, but device complexity is worsened due to additional memory and control requirements
Solution Approach 1:
The controller performs multiple functions using existing hardware resources: it manages destination information storage, checks storage status, controls operation key enablement, and executes transmission operations. By making the controller multi-functional, the system achieves transmission capability without adding separate dedicated hardware for each function, thus limiting the increase in device complexity.
Data Source
AI summary
A controller of a scanner is configured to determine whether use ID associated with a destination is stored in a memory. When it is determined that the user ID is not stored, the controller disables an operation key, and when it is determined that the user ID is stored, the controller enables the operation key. When the enabled operation key is operated, the controller executes a push scan process that generated scan data is transmitted to the destination.
