Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retrofitting incandescent traffic/rail signal housings with LED technology is challenging due to the lack of suitable anchorage points for the LED system, leading to vibration issues and misalignment of the focal point.
Innovation Solution
A lighting system with a housing and an alignment module that mounts the LED system, dampens vibrations, and automatically aligns the focal point by using a main body, pivot arm, and bias mechanisms to secure the LED system at predetermined anchoring points, preventing pivoting and shifting within the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the socket base is used to anchor the LED system in retrofitted housings, then the LED system can be mounted, but the LED system experiences vibration and misalignment due to insufficient anchorage points
Solution Approach 1:
The alignment module is divided into separate functional components: a body portion that interfaces with the housing, an arm portion that positions the LED system, and biasing mechanisms that provide independent control over mounting and alignment functions. This segmentation allows each component to optimize its specific function while working together as a integrated solution.
Solution Approach 2:
The alignment module serves as an intermediary device between the existing housing structure and the LED system. It provides the additional anchorage points and alignment control needed for reliable LED mounting without requiring modifications to the original housing, thereby enabling retrofit applications while ensuring stability.
2Ease of manufacture
If the LED system is mounted without an alignment module, then installation is simpler, but the focal point becomes misaligned during rotation or movement of the housing
Solution Approach 1:
The arm portion of the alignment module is designed to be movable relative to the body portion, allowing it to pivot and adjust the LED system's position dynamically. This dynamic capability enables the system to maintain proper focal point alignment during rotation or movement of the housing while still being relatively easy to install.
Solution Approach 2:
The biasing mechanisms (springs or elastomeric materials) provide adjustable force to maintain optimal alignment of the LED system. By changing the mechanical parameters (spring constant, pre-load force) of these biasing elements, the system can compensate for variations in housing movement and rotation, ensuring consistent focal point alignment without complex adjustment procedures.
3Reliability
If additional anchorage points are added to the housing for LED mounting, then mounting stability improves, but the housing structure becomes more complex
Solution Approach 1:
The alignment module performs multiple functions within a single integrated component: it provides additional anchorage points for stable mounting, enables precise alignment of the LED system, dampens vibrations, and allows for retrofit installation. By consolidating these functions into one module, the solution improves mounting stability without significantly increasing the overall housing structure complexity.
Solution Approach 2:
The biasing mechanisms (springs or elastomeric materials) automatically adjust to maintain optimal contact and alignment between the LED system and the housing. This self-adjusting capability eliminates the need for complex adjustment mechanisms or additional structural modifications, providing stable mounting while keeping the overall system relatively simple.
