Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial automation systems lack effective visual indicators for the operational status of electrical protection circuitry, making it difficult for operators to determine if components are safely isolated from electrical power, which can lead to exposure to high voltages during verification processes.
Innovation Solution
A system with a handle and light-emitting status indicators that provide real-time visual feedback on the operational state of electrical protection circuitry, allowing operators to verify the status without direct contact, and includes authentication mechanisms to ensure access is granted only to authorized personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators directly inspect electrical protection circuitry to verify operational status, then they can obtain accurate status information, but they are exposed to high voltage hazards
Solution Approach 1:
The patent introduces status indicator lights as an intermediary element that visually represents the operational state of electrical protection circuitry. These indicators allow operators to verify circuit status remotely without direct contact, eliminating high voltage exposure while maintaining accurate status information获取
Solution Approach 2:
The patent replaces manual physical inspection of electrical components with optical signaling through status indicator lights. This substitution eliminates the need for operators to physically approach or touch electrical circuitry, removing the hazard while preserving measurement capability
2Reliability
If electrical protection circuitry is added to the industrial automation system, then system safety is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the electrical protection circuitry: the primary protection function, status indication through integrated lights, and authentication control. By merging these functions into a single integrated system, the patent improves reliability while managing complexity through consolidation rather than adding separate independent components
Solution Approach 2:
The electrical protection circuitry is designed with multi-functionality, serving as both a safety device and an information display system. The status indicator lights provide visual feedback on circuit state, and the authentication mechanism controls access, allowing a single component to fulfill multiple roles and reduce overall system complexity
3Reliability
If authentication mechanisms are implemented for electrical protection circuitry, then system security is improved, but ease of operation decreases
Solution Approach 1:
The authentication mechanism performs verification in advance before allowing access to electrical protection circuitry. By requiring authentication prior to access, the system ensures security is established beforehand, preventing unauthorized operations while maintaining smooth access for authorized personnel through a streamlined verification process

AI summary
Embodiments of this present disclosure may include a handle disposed on an outer surface of a housing of electrical circuitry. The handle may provide access to at least a portion of the electrical circuitry. The handle may include a status indicator that emits light in response to a control signal from control circuitry. The status indicator may be disposed around the handle. The control circuitry may detect a state of the electrical protection circuitry. The control circuitry may also transmit the control signal to the status indicator based on the state. The control signal may control one or more properties of the light emitted by the status indicator, and thus indicate to an operator the state of the electrical circuitry.
