Modular Load Cell Bin System for Accurate Inventory Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load cell or scale-like devices in automated dispensing units require the removal of the platform or device for changing bin dimensions and configurations, which is inconvenient and can lead to gross errors in stock tracking due to items partially resting or wedging against compartment walls, causing friction and mechanical interference.
Innovation Solution
A load cell bin system that allows for flexible bin dimension and configuration changes without removing the platform or overall device, using a platform bin supported by load cells with a microprocessor board for accurate measurements and a modular design with interchangeable components like side walls and rear walls to adjust bin depths and widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the platform or device is removed to change bin dimensions and configuration, then the bin can be adjusted to accommodate different stock sizes, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The bin is divided into modular components including side walls, rear walls, and platform sections that can be independently adjusted or removed. This segmentation allows bin dimensions to be changed without removing the entire platform or device, resolving the contradiction between adaptability and ease of operation.
Solution Approach 2:
The bin configuration is made dynamic through adjustable side walls and rear walls that can be repositioned or removed as needed. This dynamic design enables flexible adaptation to different stock sizes while maintaining the platform in place, eliminating the need for complete device removal.
2Device complexity
If items are allowed to rest or wedge against compartment walls, then the bin configuration is simple, but gross errors occur in stock tracking due to friction and mechanical interference
Solution Approach 1:
A platform is introduced as an intermediary element between the items and the compartment walls. This platform provides a stable, level surface for items to rest on, preventing direct contact with compartment walls that would cause wedging and measurement errors, while maintaining relatively simple bin structure.
Solution Approach 2:
The platform's physical parameters such as its surface level, slope, and positioning are optimized to ensure items rest properly without wedging against walls. By controlling these parameters, the system maintains measurement precision while keeping the bin structure simple.

AI summary
A reconfigurable bin system for dispensing units, the system having a platform bin and a base member with load cells configured to support the platform bin. The platform bin itself comprises a platform plate, an optional front gate, a rear wall, and a plurality of side walls extending from the front of the platform plate to the rear wall so as to form an open-top bin. The platform plate includes a front flange disposed below the upper surface to define a trough extending across the front of the platform plate. Each of the plurality of side walls includes a rear tab received within a slot in the rear wall and a depending front tab received within the trough. A cap member may be removably secured over the trough to capture the depending front tabs within the trough, thereby securing the plurality of side walls in place.
