Solution Overview
Problem
Existing systems fail to adequately accommodate individuals with physical disabilities, such as automatically controlled doors that open and close too quickly and lack guidance on wheelchair-accessible facilities.
Innovation Solution
A security system with a kiosk that verifies credentials, uses cameras for mobility analysis, and issues special access cards to accommodate individuals with disabilities, adjusting door opening times and providing facility guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If standard automatic doors are used, then door operation speed is improved, but accessibility for physically challenged individuals deteriorates
Solution Approach 1:
The door opening time is made dynamic and adjustable based on visitor type. The system automatically detects whether a visitor has impaired mobility and adjusts the door opening duration accordingly - extending it for visitors with mobility impairments while maintaining standard timing for able-bodied visitors. This dynamic adjustment resolves the contradiction by allowing fast operation for most cases while providing extended time when needed.
Solution Approach 2:
The parameter of door opening time is changed from a fixed value to a variable parameter that adapts to visitor needs. The system modifies this temporal parameter based on detected mobility impairment status, transforming a static door operation into a flexible system that balances speed and accessibility by adjusting the timing parameter in response to visitor characteristics.
2Measurement precision
If manual door operation is required, then door control precision is improved, but operational efficiency deteriorates
Solution Approach 1:
The door control system performs self-service by automatically detecting visitor type and adjusting door opening time without manual intervention. The system uses sensors and algorithms to autonomously determine whether extended door opening is needed, eliminating the need for manual control while maintaining precise timing. This resolves the contradiction by achieving automated precision that matches or exceeds manual control while significantly improving operational efficiency.
Solution Approach 2:
The system implements feedback mechanisms where sensors detect visitor characteristics (such as mobility impairment) and feed this information back to the door control system. Based on this feedback, the system automatically adjusts door opening parameters in real-time, achieving precise control through automated feedback loops rather than manual operation, thus resolving the contradiction between precision and efficiency.
3Ease of operation
If individualized accommodation is provided, then visitor satisfaction is improved, but system complexity deteriorates
Solution Approach 1:
The system uses visual copying/detection of visitor characteristics through cameras and sensors to automatically identify mobility impairment status. Instead of requiring complex manual assessment procedures, the system creates visual copies of the visitor's movement patterns and compares them against stored profiles of mobility impairment characteristics. This automated copying approach provides individualized accommodation while keeping system complexity manageable through pattern recognition rather than complex decision-making algorithms.
Solution Approach 2:
The system replaces complex manual assessment mechanisms with automated sensor-based detection. Instead of requiring human judgment or complex mechanical evaluation procedures, the system uses optical sensors, cameras, and algorithmic analysis to automatically detect mobility impairment. This substitution of mechanical/manual systems with sensor-based automation reduces overall system complexity while enabling more sophisticated individualized accommodation through objective data collection and processing.
Data Source
AI summary
Systems, methods and software products directed to allowing a user to access a facility or other controlled space using credentials. The user is queried as to whether the user has impaired mobility. In response to an affirmative response to the query, the user's status is confirmed such as by reference to security camera data to confirm the user's impaired mobility. If the user is confirmed as having mobility, a special access card and assistance are provided to the user by the security or access control system and, otherwise, a normal access card is provided.
