Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial environments, implementing security guidelines on IoT devices can impair ongoing operations due to potential delays and safety risks, making it difficult to enforce security policies without disrupting regular processes.
Innovation Solution
A method for operating networked IoT devices in automation networks that dynamically selects security functions based on device states, allowing continuous operation without disrupting productivity by using a database of security measures tailored to the device's current state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security measures are implemented on IoT devices, then security protection is improved, but productivity deteriorates due to process interruptions and delays
Solution Approach 1:
The system dynamically selects security functions based on current device state and operational context. Rather than enforcing security measures uniformly, the system adapts security enforcement to match current productivity requirements and operational priorities, allowing critical processes to maintain high productivity while still receiving appropriate security protection.
Solution Approach 2:
The patent implements partial security enforcement by selecting specific security functions based on device state rather than applying all security measures uniformly. This partial action approach applies security protection where and when it is most needed, avoiding unnecessary security overhead that would reduce productivity while maintaining adequate security coverage.
2Reliability
If encryption and security protocols are enforced on all terminals, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments security functions into multiple selectable options rather than implementing a single comprehensive security protocol on all devices. Different security functions are assigned to different device states and operational contexts, reducing the complexity burden on individual devices while maintaining overall system security through diversified security approaches.
Solution Approach 2:
The system applies different security functions to different local contexts (device states, applications, communication environments). Rather than enforcing uniform security protocols across all terminals, each device receives security measures tailored to its specific operational context, reducing unnecessary complexity while maintaining appropriate security levels.
