Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial automation systems lack effective visual indicators for determining the operational status of electrical protection circuitry, which can lead to unsafe conditions for operators, as they often rely on manual verification methods that expose them to high voltages.
Innovation Solution
A system with a handle-mounted status indicator that emits light based on the operational state of the electrical protection circuitry, allowing operators to visually assess the status from a safe distance, and includes authentication mechanisms to ensure access is granted only to authorized personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification methods are used to check electrical protection circuitry status, then operators can determine circuit state, but operators are exposed to high voltages and unsafe conditions
Solution Approach 1:
A status indicator light is introduced as an intermediary element that visually represents the electrical protection circuitry state. The light provides indirect information about circuit status without requiring direct contact with high voltage components, thereby eliminating operator exposure to electrical hazards while maintaining reliable status determination
Solution Approach 2:
The patent replaces manual mechanical verification methods with an optical signaling system. Instead of physically inspecting or testing electrical components, operators use visual status indicators (lights) to determine circuit state, substituting a safe optical detection method for dangerous manual electrical verification
2Reliability
If status indicators are added to electrical protection circuitry, then operator safety is improved through visual feedback, but device complexity increases
Solution Approach 1:
The patent employs color-changing light indicators to communicate different electrical protection circuitry states. Different colors represent different operational conditions (e.g., green for safe, red for dangerous), providing intuitive visual feedback without requiring complex display systems or multiple indicator components
Solution Approach 2:
The status indicator system is designed to automatically reflect the electrical protection circuitry state without requiring additional control mechanisms. The indicator self-regulates based on circuit conditions, eliminating the need for complex control logic or manual operation while providing continuous visual status information
3Reliability
If authentication mechanisms are implemented on handles, then secure access is ensured, but ease of operation is reduced
Solution Approach 1:
Authentication is performed as a preliminary action before handle operation is permitted. The system verifies operator credentials in advance through biometric or card-based authentication, and only after successful verification does the handle become operable. This ensures security while maintaining ease of operation for authorized users through a streamlined one-time authentication process

AI summary
Embodiments of this present disclosure may include a handle (92)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 (94) 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.
