Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identification methods for industrial automation devices, such as name plates, are inefficient and time-consuming, as they require close reading and are not easily reusable or adaptable, leading to costly downtime in industrial settings.
Innovation Solution
The use of indicators made from thermochromic materials and rubberized plastic or silicone, which can be attached without fasteners and provide color coding and temperature indication, allowing quick identification of devices and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional identification methods (name plates) are used for industrial automation devices, then device identification is possible, but identification time is excessive and worker efficiency is reduced
Solution Approach 1:
The patent applies color-coded indicators attached to industrial automation devices to enable rapid visual identification. Different colors represent different device types or statuses, allowing workers to instantly distinguish between devices without reading detailed name plates. This directly reduces identification time and improves worker efficiency in panels with many similar devices.
2Speed
If indicators are attached to industrial automation devices, then identification speed is improved, but device complexity increases due to additional components
Solution Approach 1:
The identification system is segmented into separate, removable indicator components rather than integrating identification features directly into the device housing. This allows the indicators to be independently attached and removed without modifying the core device structure, thus improving identification speed while minimizing added complexity.
Solution Approach 2:
The indicators are designed as universal components that can be attached to multiple different device types using standard attachment methods. This multi-functionality reduces the need for device-specific identification features, improving identification speed across various devices while avoiding the complexity of custom solutions for each device type.
3Temperature
If thermochromic materials are used for indicators, then temperature indication capability is added, but manufacturing complexity increases
Solution Approach 1:
The patent incorporates thermochromic materials into the indicators that change color in response to temperature variations. This allows the same indicator component to provide both visual identification and temperature monitoring functions. The thermochromic property is integrated into the material selection rather than adding separate sensing mechanisms, thus adding temperature indication capability while keeping manufacturing relatively simple.
