Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual definition of access control systems in facilities is time-consuming and inconsistent, and poses difficulties in updating boundaries and access policies due to changes in facility layouts.
Innovation Solution
Automating the deployment of access control systems by extracting two-dimensional spaces from building information models, determining connections between spaces, defining access zones, and associating access readers with zone boundaries, thereby enabling efficient and consistent configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual definition of boundaries, security zones and access policies is used, then flexibility in customization is improved, but configuration time and inconsistency increase
Solution Approach 1:
The system performs preliminary actions by automatically extracting spatial information from building information models and pre-defining boundaries, security zones, and access policies based on the facility layout. This preliminary automated configuration eliminates the need for manual definition while maintaining adaptability, as the system can be customized by simply updating the BIM data source.
2Adaptability or versatility
If manual definition of boundaries, security zones and access policies is used, then customization control is improved, but consistency and reliability decrease
Solution Approach 1:
The system performs self-service by automatically extracting spatial data from building information models and generating consistent security zone definitions and access policies without manual intervention. This automated self-configuration ensures reliability and consistency across all facility areas, while customization control is maintained through the ability to modify the underlying BIM data or adjustment parameters.
3Adaptability or versatility
If manual updates following changes in facility spaces are performed, then adaptability to changes is improved, but difficulty and time consumption increase
Solution Approach 1:
The system performs preliminary actions by establishing automated links between building information models and access control configurations. When facility spaces change, the system proactively detects these changes in the BIM data and automatically updates boundaries, security zones, and access policies, eliminating manual update efforts and reducing complexity.
4Productivity
If automated extraction of spaces from building information models is implemented, then configuration time and consistency are improved, but system complexity increases
Solution Approach 1:
The system uses building information models as an intermediary data source that contains pre-processed spatial information. By extracting data from this standardized intermediate format, the system achieves automated configuration with high productivity while managing complexity, as the BIM serves as a prepared data layer between the facility design and access control system.
