Multi-Shape Article Supply Device With Detection-Based Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article supply devices are limited to supplying articles of a specific shape, requiring separate devices for different shapes, which is inefficient and inflexible.
Innovation Solution
An article supply device capable of accommodating and dispensing both spherical and flat articles, utilizing detection units to identify the presence or absence of each type, and a lock mechanism to prevent dispensing when empty, with visual and light-based notification systems to inform users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated article supply device is designed for a specific article shape, then the supply reliability for that shape is improved, but the adaptability to various article shapes deteriorates
Solution Approach 1:
The patent implements a single article supply device that can handle multiple types of articles (spherical articles and flat articles) by providing different accommodation units for different article shapes. The detection unit identifies the article type and the lock unit controls supply accordingly, allowing one device to perform functions that would traditionally require multiple dedicated devices, thus improving adaptability while maintaining supply reliability for each article type.
2Manufacturing precision
If multiple dedicated article supply devices are used for different article shapes, then the supply precision for each shape is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple dedicated article supply devices into a single integrated device. Different accommodation units (first accommodation unit for spherical articles, second accommodation unit for flat articles) are merged within one device body, sharing common components like the detection unit and lock unit. This merging maintains the supply precision of dedicated devices while reducing overall system complexity and space requirements.
Solution Approach 2:
The device employs dynamic configuration where the accommodation units can be selectively attached or detached from the main body based on the type of articles to be supplied. This dynamic adaptability allows the device to optimize its structure for different article types, maintaining high supply precision while avoiding the complexity of permanently incorporating all possible accommodation units.
3Reliability
If the lock unit prevents supply when articles are absent, then the operational reliability is improved, but the ease of operation deteriorates due to additional locking mechanisms
Solution Approach 1:
The lock unit operates autonomously based on signals from the detection unit. When the detection unit identifies that no articles are present in the accommodation unit, the lock unit automatically engages to prevent supply operations. When articles are detected, the lock unit automatically releases. This self-service mechanism eliminates the need for manual locking/unlocking by the user, maintaining operational reliability while actually improving ease of operation compared to manual locking systems.

AI summary
An article supply device capable of supplying first and second type articles comprises a main body, an accommodation unit for accommodating articles, a supply unit for supplying articles accommodated in the accommodation unit, a lock unit which prevents articles from being supplied from the supply unit; and a detection unit capable of detecting the presence or absence of first type articles and the presence or absence of the second type articles accommodated in the accommodation unit, wherein the lock unit is turned into a lock state, on condition that the absence of the articles is detected by the detection unit.
