Automated Storage Rack Carrier Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage product carriers lack effective access control, leading to potential errors in picking items, which can result in incorrect parts being selected, causing machinery failure, customer dissatisfaction, or even safety issues, especially in cases like medication retrieval.
Innovation Solution
The proposed storage product carrier and automated storage rack implement controlled access to compartments using locking devices with indicators and a centralized control system, allowing only authorized users to access specific compartments, with locking mechanisms that can be independently controlled and remotely managed, and include features like inspection openings and position detectors for secure and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access control is implemented using locking devices for each compartment, then security and error prevention are improved, but device complexity increases
Solution Approach 1:
Multiple locking devices are controlled through a single centralized control unit that receives access requests and sends unified control signals to all locking devices. This merging of control functions reduces operational complexity while maintaining individual compartment security through centralized management.
Solution Approach 2:
The control unit serves multiple functions: it manages access rights for different user groups, controls multiple locking devices, provides visual feedback through indicators, and coordinates with the automated storage/retrieval system. This multi-functionality consolidates what would otherwise be separate systems into a single integrated solution.
2Ease of operation
If indicators are provided for each compartment to show access status, then user orientation and ease of operation are improved, but device complexity increases
Solution Approach 1:
Visual indicators use color changes or light emission to communicate compartment access status to users. This provides immediate, intuitive feedback about which compartments can be accessed, improving user orientation without requiring complex interfaces or user education.
Solution Approach 2:
The indicator system automatically provides access status information without requiring user intervention or external control. The system self-regulates by displaying which compartments are accessible based on the user's access rights and the current state of locking devices.
3Ease of operation
If centralized control device is used to manage all locking devices, then ease of operation and control are improved, but device complexity increases
Solution Approach 1:
The control unit consolidates multiple control functions into a single device that manages all locking devices, indicators, and access rights. This merging eliminates the need for separate control mechanisms for each compartment, simplifying user interaction while centralizing system intelligence.
Solution Approach 2:
The control unit acts as an intermediary between the user interface and the physical locking devices. It translates user access requests into appropriate control signals for individual locking devices, providing a simplified interface while managing the complexity of individual device control in the background.
4Ease of operation
If inspection openings are provided in closing means, then ease of operation and verification are improved, but security may be compromised
Solution Approach 1:
The inspection opening extracts only the verification function from the closing means, allowing users to check compartment contents without fully opening the compartment. This separates the inspection function from the access function, maintaining security while enabling verification.
Solution Approach 2:
The inspection opening serves as an intermediary that allows partial viewing of compartment contents without providing full access. It mediates between the security requirement (keeping compartments closed) and the verification need (allowing users to check contents), enabling one function without completely compromising the other.

AI summary
A storage product carrier (10) for a storage rack comprising a plurality of carrier supports spaced one above the other, arranged in pairs on opposite side walls of the storage rack and able to support the storage product carrier (10) which is conveyable by means of an automatic storage/retrieval device and an access opening for accessing the storage product carriers (10) has a multitude of compartments (16) having openings. Closing means (18) are provided to cover at least one of the openings, wherein a locking means is provided to lock the closing means (18) in the openings and wherein the locking means can be controlled to lock the closing means (18) in the opening or to allow the closing means (18) to be moved such that the opening becomes accessible.
