Indicator Device Sliding Members Stock Refill Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In manufacturing and assembly processes, frequent component usage leads to mixing and stock management issues, resulting in component residue, damage, and batch tracing difficulties due to inadequate inventory control and mixing of different batches.
Innovation Solution
An indicator device that clearly signals when the upper loading chamber of a dispensing device needs refilling and confirms when the refilling action has been taken, using sliding members and optional electronic tags to prevent incorrect movement and facilitate non-visual status monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lidded trays or bins are used to prevent mixing of components, then component mixing is reduced, but it becomes difficult to monitor stock levels and manage refilling efficiently
Solution Approach 1:
The system enables automatic stock level monitoring through sensors that detect when components are low without requiring manual inspection. The indicator device automatically signals when refilling is needed, allowing the system to monitor itself rather than requiring human intervention for stock checks.
Solution Approach 2:
The indicator device provides visual feedback (lights or displays) that communicates stock levels to operators. When components are low, the system generates a signal that is immediately visible, creating a feedback loop that informs operators when refilling is necessary without requiring them to open lids and manually check stock levels.
2Quantity of substance
If manual stock monitoring and refilling is performed, then stock levels can be maintained, but component residue accumulates at the base of trays and components may be damaged
Solution Approach 1:
The system triggers refilling actions before components are completely depleted by detecting low stock levels in advance. The indicator device signals when components are running low, allowing operators to refill before the tray is completely empty, preventing the accumulation of residue and potential damage to components that would occur with manual monitoring.
Solution Approach 2:
The patent replaces manual mechanical monitoring (opening lids, visually inspecting stock levels) with an automated sensor-based detection system. This substitution eliminates the need for operators to physically handle components during monitoring, reducing the risk of damage and residue accumulation from improper handling.
3Productivity
If different batches of components are mixed together to maintain stock levels, then continuous supply is ensured, but batch tracing becomes impossible when component failures occur
Solution Approach 1:
The system divides the stock management into discrete, traceable units by maintaining separate storage locations for different batches. Each batch can be independently monitored and tracked, allowing the system to maintain continuous supply through organized batch management rather than mixing, thereby preserving batch tracing capability while ensuring productivity.
4Productivity
If a large stock is maintained to ensure continuous production, then production continuity is maintained, but the likelihood of component damage increases and batch tracing becomes difficult
Solution Approach 1:
The sensor-based monitoring system detects low stock levels before complete depletion occurs, triggering timely refilling actions. This preliminary detection ensures production continuity by preventing stockouts while allowing operators to refill in controlled batches rather than maintaining excessively large stocks, thereby reducing component damage risks from prolonged storage.

AI summary
An indicator device comprises a first slide member (22) mounted on a planar base (1). The first slide member (22) is displaceabie between a first position in which it reveals a first status indicating area (26) indicative of a first condition or state and a second position in which it reveals a second status indicating area (28) indicative of a second condition or state. A second slide member (30) is mounted on the base (10) and is displaceabie into and across the path of the first indicator member (22) when the first indicator member is in the first position, to inhibit displacement of the first indicator member. The second indicator member (30) is displaceabie between a first position in which it does not inhibit the displacement of the first indicator member (22) and a second position in which it inhibits the displacement of the first indicator member to its second position. The device may also be provided with one or more RFID tags (80, 82, 84) to permit remote monitoring of the status of the device. The device can be used, for example, in conjunction with a dispenser (60) to provide an indication of when stock needs to be reordered and whether reordering of the stock has taken place.
