Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The hospitality industry faces significant operational costs due to the inadvertent disposal of metal flatware and equipment in waste receptacles, with existing solutions either requiring users to reach into the receptacle to retrieve items or lacking in ease of use and maintenance.
Innovation Solution
A metal detection apparatus comprising a base with a pivotally attached tray and handle, equipped with a metal detector and control electronics that alerts users to the presence of metal articles, allowing for easy retrieval before disposal and featuring a button-activated mechanism for convenient operation and low maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal detector is mounted on a waste receptacle to detect metal flatware, then metal articles can be detected and retrieved, but the device complexity increases
Solution Approach 1:
The metal detection apparatus is nested within the waste receptacle structure itself. The base fits over the receptacle opening, the tray nests within the base, and the detector coil is integrated into the tray assembly. This nesting approach allows the detection system to be mounted on existing waste receptacles without requiring separate complex mounting structures, thereby improving detection reliability while minimizing device complexity.
Solution Approach 2:
The waste receptacle serves multiple functions: it collects food waste and simultaneously houses the metal detection apparatus. The base provides both structural support for the detector and a mounting interface for the waste receptacle. The tray serves as both a food waste container and a platform for the detection coil. This multi-functionality reduces the need for separate dedicated detection devices, lowering overall system complexity.
2Ease of operation
If a tray is added to allow easy retrieval of metal items, then ease of operation improves, but the device complexity increases
Solution Approach 1:
The tray is designed to be removable from the base, providing dynamic adaptability. When metal detection is needed, the tray is in place to catch and display detected items for easy retrieval. When not in use, the tray can be removed to simplify the structure and reduce cleaning requirements. This dynamic configuration improves ease of operation for metal retrieval while avoiding permanent complexity in the device structure.
Solution Approach 2:
The apparatus is segmented into distinct removable components: the base, the tray, and the detector assembly. This segmentation allows the tray to be easily removed and reattached, improving ease of operation for both metal retrieval and device maintenance. The segmented design enables users to access the tray without disassembling the entire device, reducing operational complexity while maintaining ease of use.
3Measurement precision
If a detector coil surrounds the vertical walls to detect metal, then detection precision improves, but the device complexity increases
Solution Approach 1:
The detector coil is nested within the tray structure, specifically positioned beneath the tray bottom to form a detection zone. This nested arrangement allows the coil to surround the vertical walls of the tray, creating an effective detection field for metal objects placed on or in the tray. The nesting approach integrates the detection function into the existing tray structure without requiring separate complex coil mounting arrangements, thereby improving detection precision while minimizing added complexity.

AI summary
An apparatus to prevent workers from inadvertently discarding metal articles is used in the hospitality industry. The apparatus includes a base suitable for mounting to an open end of a waste receptacle, a tray pivotally mounted to the base, and a metal detector mounted to the underside of the tray. The metal detector detects the presence of metal articles deposited in the tray amidst food scraps or other waste. The metal detector signals an audible alarm alerting workers to the presence of metal articles in the waste. Once the metal articles are removed, the worker can use a handle or a button system to pivot the tray, so as to deposit the food scraps or other waste in the waste receptacle.
