Rotating Holder for Traffic Signal Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic signaling systems require complete shutdown and lengthy repair times due to the need to open the entire housing for module replacements, leading to traffic disruptions and potential light signal obscuration during maintenance, even with redundant systems.
Innovation Solution
A housing with a rotatably mounted holder containing multiple slots allows for module exchange without shutting down the system, using a side opening that can be aligned with slots by rotating the holder, enabling quick and dustproof/watertight replacement without dismantling the housing, and utilizing latching means for secure assembly positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire housing is opened for module replacement, then the defective element can be accessed and replaced, but the system must be shut down and road traffic is impaired
Solution Approach 1:
The housing is segmented into a main body and a removable cover that can be opened independently. This allows access to the holder and slots without opening the entire housing, enabling module replacement while keeping the system operational and avoiding traffic impairment.
Solution Approach 2:
The defective module is extracted from the holder through the opened cover without requiring removal of the entire housing. This extraction process allows replacement of individual modules while maintaining system availability and avoiding complete shutdown.
2Ease of repair
If the housing is opened for module replacement, then the module can be accessed, but the light signal is obscured and road traffic is impaired
Solution Approach 1:
The housing is divided into sections with a removable cover that provides access to specific slots. This segmentation allows opening only the necessary portion of the housing, keeping the light signal visible and avoiding road traffic impairment while maintaining module accessibility.
3Reliability
If multiple slots are provided for redundant modules, then fault tolerance is improved, but the device complexity increases
Solution Approach 1:
The holder is designed as a universal structure with multiple identical slots that can accommodate different types of modules (light sources, electronics, sensors). This multi-functional design provides fault tolerance through redundancy while avoiding excessive complexity by using a standardized, repeatable slot configuration.
