Hinged Cover Assembly for Automatic Replenishment Stock Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User compliance in restock requests within the kanban system is a significant shortcoming, as it relies on manual visual inspection and user-initiated actions, leading to inefficiencies and potential stockouts.
Innovation Solution
A single bin is divided into two sections, with a hinged cover assembly that automatically signals the need for restocking when the front section is depleted, using a wireless transmitter to notify the system, ensuring that restocking becomes an integral part of the user's workflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually signal restock needs by placing empty bins in a restock collection area, then the system can track inventory status, but user compliance is poor and the process is inefficient
Solution Approach 1:
The system performs restock detection automatically without requiring user action. The detector mounted on the hinged cover assembly self-activates when the cover is opened, automatically transmitting restock signals without user intervention, thus eliminating compliance issues while maintaining productivity
Solution Approach 2:
The manual mechanical process of placing bins in collection areas is replaced by an automated detection system using wireless transmitters and detectors. This substitution eliminates the need for user compliance while improving restock request efficiency through automatic sensing and signaling
2Extent of automation
If a detector is mounted on the hinged cover assembly to automatically detect when the front section is depleted, then restock requests become automatic and compliance improves, but device complexity increases
Solution Approach 1:
The hinged cover assembly serves multiple functions: it provides physical access control to the rear section, acts as a mounting structure for the detector, and triggers the restock signal when opened. This multi-functionality reduces overall system complexity by consolidating components rather than adding separate elements
Solution Approach 2:
The detector is integrated with the hinged cover assembly rather than being a separate component. This merging of the signaling mechanism with an existing structural element minimizes additional complexity while achieving automatic restock detection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances user compliance by automating the restock request process, reducing manpower requirements and minimizing the risk of stockouts, while maintaining a low-power, long-lasting wireless communication system.
Implementation Method 1
The action of lifting the lid is the only way the user can access those parts and allows a detector mounted on that hinged cover assembly to transmit a signal to indicate parts for that specific bin are needed. That signal can be wirelessly transmitted using a wide variety of wireless technologies such as Wi-Fi, Zigbee, Blue Tooth Beacon, or proprietary wireless transmitter/receiver methods.

AI summary
A system for automatic reordering of replenishment stock is described herein. The system generally comprises a storage bin defining a first compartment and a second compartment in proximity to the first compartment where the storage bin is configured to store a predetermined product. A cover assembly may normally restrict access to the second compartment. When the product is exhausted from the first compartment, opening the cover assembly to access the product in the second compartment may trigger a sensor in proximity to the second compartment. This triggering causes the sensor to wirelessly transmit a signal to a processor to reorder a quantity of the product.
