Rotatable Faceplate for Circuit Breaker Information Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit breakers face challenges in displaying critical information in a readable orientation, especially during installation and inspection, due to fixed label positions that may not align with the operator's field of view, leading to difficulties in reading and scanning essential ratings and instructions.
Innovation Solution
A rotatable faceplate system for switching devices, including circuit breakers, that allows the information display to be adjusted to optimal reading orientations by securing a faceplate to the device and rotating it with respect to the cover and handle, ensuring visibility regardless of the device's installation orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed label position is used on the circuit breaker, then the device structure is simple and manufacturing is easy, but the information cannot be read in optimal orientation during installation and inspection
Solution Approach 1:
The faceplate is designed to be rotatable relative to the circuit breaker body, allowing operators to dynamically adjust the information orientation to match their viewing angle and installation orientation. This dynamic adjustment capability resolves the contradiction by enabling optimal information readability without requiring multiple fixed label positions or complex reconfiguration mechanisms.
Solution Approach 2:
The information display system is segmented into a separate rotatable faceplate component that can be independently adjusted. This segmentation allows the faceplate to be rotated to different orientations while the main circuit breaker body remains fixed, providing flexibility in information presentation without complicating the overall device structure.
2Adaptability or versatility
If the circuit breaker is installed in different orientations, then the device is versatile and adaptable to various installation scenarios, but the fixed information label becomes difficult or impossible to read
Solution Approach 1:
The rotatable faceplate allows the information display to dynamically adapt to any installation orientation of the circuit breaker. Whether the breaker is installed vertically, horizontally, or at any angle, the faceplate can be rotated to present the information in a readable orientation, thus maintaining information visibility across all installation scenarios.
Solution Approach 2:
The rotatable faceplate mechanism provides universal adaptability to accommodate any installation orientation. A single faceplate design can serve multiple installation configurations (vertical, horizontal, angled) by simply rotating to the appropriate orientation, eliminating the need for orientation-specific label placements or multiple label sets.
3Ease of operation
If information is placed on the face of the circuit breaker for operator visibility, then the information is accessible during operation, but the label cannot be rotated to match different viewing angles
Solution Approach 1:
The faceplate is designed with rotational capability that allows operators to adjust the information orientation to match their viewing angle and hand position during operation. This dynamic adjustment maintains information accessibility while adding orientation versatility, resolving the contradiction between fixed placement and flexible viewing.
