Multi-Compartment Key Safe for Time-Limited Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing key safe systems lack individual control over access, leading to multiple safes, uncontrolled access by multiple people, no timing management, and inefficient coordination of key access for different users.
Innovation Solution
A key access system with electronic locks, remote communication modules, and digital locks that allow controlled access to multiple compartments with time-limited access based on predefined criteria, using RFID technology for key management and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple safes are used to control access to different keys, then access control is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple key storage compartments into a single key safe unit, allowing multiple keys to be stored and accessed through one integrated system rather than requiring separate safes for each key. This reduces the number of physical devices while maintaining access control capabilities.
Solution Approach 2:
The key safe is designed with multiple key compartments that can store different keys, making a single device capable of managing multiple access credentials. The system provides universal access control functionality for various keys through one unified interface and control mechanism.
2Ease of operation
If master keys are used to provide access to multiple people, then ease of operation is improved, but access control and security deteriorate
Solution Approach 1:
The system segments access control by providing individual codes or credentials to different users, allowing each user to access only their authorized keys. This divides the master key functionality into multiple controlled access points, maintaining ease of operation while improving security and access control.
Solution Approach 2:
The key safe system incorporates feedback mechanisms to track and record which user accessed which key compartment and when. This provides accountability and control over key distribution, ensuring that access is properly monitored and managed without requiring physical presence of the authorizing user.
3Reliability
If individual control systems are provided for each user, then access control is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent merges individual access control capabilities into a single key safe system with multiple key compartments. Each compartment can be accessed by different users with different codes, providing individual control within one unified device rather than requiring separate systems for each user.
Solution Approach 2:
The key safe provides universal access control functionality by accommodating multiple users and multiple keys within one system. The single device performs the functions of multiple individual control systems through its multiple compartments and code-based access mechanism.
4Reliability
If the authorizing user must physically attend to the safe to provide access, then access control is improved, but productivity and convenience deteriorate
Solution Approach 1:
The key safe system enables self-service access by allowing users to independently open compartments using their assigned codes without requiring the authorizing user to be physically present. The system automatically validates credentials and provides access, eliminating the need for manual intervention while maintaining security.
Solution Approach 2:
The patent replaces the mechanical system of physical key insertion and manual locking with an electronic code-based access system. This substitution allows for automated authentication and compartment release, improving efficiency and eliminating the need for physical attendance by the authorizing user.

AI summary
A method and apparatus for use in aiding provision of services requiring access through a physical key including the steps of providing a plurality of compartments with a digital lock for receiving the physical key and including the step of transmitting to a user providing the service with one or more of a digital keycode, time access key, and identity tag. The digital lock is activatable to open the identified compartment by receipt through a sensor of digital keycode and time access key and comparison of the time access key with the clock.
