System and Method for Facilitating Access to a Secured Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable barrier operator systems do not effectively limit access to secured areas once a guest has passed through the initial barrier, such as a garage door, potentially allowing unauthorized access to adjacent areas like homes or buildings.
Innovation Solution
A system that includes a movable barrier operator and a passageway door lock, where the operator receives a control signal with a code to determine whether it is a primary or secondary signal. Primary signals allow access to both the garage door and the passageway door, while secondary signals only open the garage door and keep the passageway door locked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If temporary or one-time use codes are provided to guests for garage access, then guest convenience is improved, but security of adjacent areas deteriorates because guests can access the garage without restriction on further movement
Solution Approach 1:
The access control system is segmented into two distinct components: a movable barrier operator for the garage door and a stationary door lock for the passageway door. This segmentation allows independent control of each barrier, enabling the garage door to open for guests while the passageway door remains locked, thus resolving the security issue without compromising guest convenience
Solution Approach 2:
A control system acts as an intermediary between the garage door operator and the passageway door lock. This intermediary receives signals from the garage door operator and automatically responds by locking or unlocking the passageway door based on whether the signal is primary or secondary, eliminating the need for manual key management while maintaining security
2Adaptability or versatility
If multiple guests are granted temporary entry codes, then guest access capability is improved, but the need for physical keys increases and security management becomes more complex
Solution Approach 1:
The mechanical key system is replaced with an electronic access control system that uses coded signals. The stationary door lock responds automatically to signals from the garage door operator, eliminating the need for physical keys and simplifying access management while maintaining the ability to grant access to multiple guests
Solution Approach 2:
The garage door operator is given multiple functions: it not only controls the garage door but also serves as a signal source for the passageway door lock. This multi-functionality allows a single device to manage both barriers, reducing overall system complexity while providing versatile access control
3Reliability
If the passageway door is kept locked to prevent unauthorized access, then security is improved, but ease of access for authorized persons deteriorates requiring them to carry keys
Solution Approach 1:
The passageway door lock is pre-configured to respond automatically to signals from the garage door operator. When a primary signal is detected, the lock automatically unlocks before the person needs to manually access it, eliminating the need to carry keys while maintaining security through automatic authentication
Data Source
AI summary
In one aspect, a portable electronic device is provided for accessing a secured area to deliver a package therein. The portable electronic device includes a sensor configured to detect an indicium of the package and communication circuitry configured to communicate a message to a server computer associated with the package upon the sensor detecting the indicium. The communication circuitry is further configured to receive delivery information from the server computer, the delivery information including at least a location of the secured area. The portable electronic device further includes a processor operatively coupled to the sensor and the communication circuitry. The processor is configured to cause, via the communication circuitry, the movable barrier operator to open a movable barrier associated with the secured area.
