Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household electrical appliances connected to networks are vulnerable to computer virus infections, leading to potential malfunctions and damage, and not all family members may be equipped to take appropriate countermeasures, posing a risk of further damage if left unaddressed.
Innovation Solution
A processing apparatus with a detection unit, status retrieval unit, and countermeasure storage unit that can detect viruses and perform appropriate countermeasures based on the appliance's status and user information, including proactive measures like scheduling backup and disconnecting from networks to prevent spread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic virus detection and countermeasure execution is implemented, then virus response effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple countermeasure options (data backup, network disconnection, power shutdown) in the countermeasure storage unit before virus infection occurs. When a virus is detected, the system automatically selects and executes the appropriate pre-prepared countermeasure based on the current operational status, eliminating the need for complex real-time decision-making algorithms and reducing system complexity while maintaining high response effectiveness.
Solution Approach 2:
The system achieves self-service through the automatic virus detection and countermeasure execution mechanism. The detection unit continuously monitors for viruses, and upon detection, the countermeasure unit autonomously retrieves and implements the appropriate countermeasure from storage without requiring user intervention. This self-service capability improves virus response effectiveness while keeping the system relatively simple by eliminating the need for complex user interfaces or manual intervention protocols.
2Reliability
If multiple countermeasure options are prepared based on operational status, then virus damage minimization is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality by tailoring the countermeasure to the specific operational status of the device. Different countermeasures (data backup for recording status, network disconnection for playback status, power shutdown for idle status) are prepared and stored for different operational conditions. This status-specific approach ensures optimal damage minimization for each scenario while keeping the management complexity manageable through clear status-based categorization.
Solution Approach 2:
The system utilizes parameter changes by transitioning between different operational statuses (recording, playback, idle) and corresponding countermeasure selections. The countermeasure storage unit organizes multiple countermeasure options associated with different status parameters, allowing the system to adaptively select the appropriate countermeasure based on the current status parameter value. This parameter-driven approach improves damage minimization effectiveness while maintaining systematic organization.
3Adaptability or versatility
If user information is considered in countermeasure selection, then countermeasure appropriateness is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-storing user information (such as user identifiers, contact information, and authority levels) in the countermeasure storage unit alongside the countermeasure options. When a virus is detected, the system retrieves the current user information and automatically matches it with the appropriate countermeasure based on pre-defined criteria. This pre-configured user information integration improves countermeasure appropriateness while avoiding complex real-time user assessment algorithms.

AI summary
A processing apparatus is connected to a network and has a content recording/playback function. The processing apparatus stores therein, in correspondence, (i) statuses of the recording/playback process and (ii) computer virus-handling processes to be performed if a detection unit detects a computer virus. If the computer virus is detected, the processing apparatus performs one of the computer virus-handling processes in correspondence with one of the statuses of the recording/playback processes.
