Article Supply Device with Integrated Detection and Sold-Out Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article supply devices cannot detect the presence or absence of articles accommodated in the supply box, leading to inefficiencies in operation and management.
Innovation Solution
An article supply device is designed with a detection unit that uses an up and down moving pin to detect the presence or absence of articles, a transmission unit to signal when articles are depleted, and a sold-out display unit to visually indicate the absence of articles, allowing for integrated operation of these components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an article supply device is designed without detection capability, then the device structure remains simple, but the device cannot detect the presence or absence of articles leading to operational inefficiency
Solution Approach 1:
A detection pin is introduced as an intermediary component that physically contacts the articles to detect their presence or absence. This simple mechanical intermediary enables detection functionality without requiring complex sensors or electronic systems, thus improving operational efficiency while maintaining relatively simple device structure.
Solution Approach 2:
The detection pin automatically detects article status through its own movement driven by spring force and article contact. The system serves itself by using the physical interaction between the detection pin and articles to generate detection signals, eliminating the need for external power sources or complex detection mechanisms.
2Loss of information
If a detection unit is added to detect article presence, then article depletion can be detected, but the device complexity increases due to additional transmission and display units
Solution Approach 1:
The transmission unit and sold-out display unit are merged into an integrated assembly that moves together with the detection pin. This combining of multiple functional units into a single integrated structure reduces the number of separate components and simplifies the overall device architecture while still providing both detection and visual indication functions.
Solution Approach 2:
The integrated transmission and display unit serves multiple functions: it transmits the detection signal from the detection pin and simultaneously provides visual indication of article depletion. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall device complexity.
3Ease of operation
If the transmission unit and sold-out display unit are operated separately, then each function can be optimized independently, but the operation becomes complex requiring multiple independent mechanisms
Solution Approach 1:
The transmission unit and sold-out display unit are mechanically coupled to move together as a single integrated assembly. This merging allows both functions to be activated simultaneously by a single detection event, greatly simplifying operation while the internal mechanism handles the coordination of multiple functions through unified motion.

AI summary
An article supply device capable of detecting the presence or absence of articles and supplying the articles, includes a main body, an accommodation unit for accommodating the articles, a supply unit for supplying the articles accommodated in the accommodation unit, an up and down moving pin (detection unit) for detecting the presence or absence of the articles accommodated in the accommodation unit, a transmission unit for transmitting a signal indicating the absence of articles accommodated in the accommodation unit, and a sold-out display unit for displaying the absence of the articles accommodated in the accommodation unit. The transmission unit and the sold-out display unit are configured to operate integrally based on a detection operation of the detection unit.
