Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of flashing light beacons for vehicles is complicated due to the radial positioning of LEDs, making it difficult to connect each light to the controller effectively during assembly.
Innovation Solution
The design features a base with LED arrays and a common circuit board, where each LED array has a circuit board extending upwardly with electrical connectors that are identical to those on the common circuit board, allowing for easy electrical connection through spade terminals and sockets, facilitating simultaneous connection and rotation without disconnecting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LEDs are positioned in radial configuration to provide 360-degree light coverage, then the beacon provides comprehensive signal lighting in all directions, but the complexity of connecting each LED to the controller increases significantly
Solution Approach 1:
The beacon is divided into multiple independent LED modules, each containing a subset of LEDs arranged in radial positions. Each module has its own circuit board with connectors that interface with a central controller board. This segmentation allows the complex radial LED array to be broken into manageable units that can be connected systematically rather than requiring individual wiring of each LED to the controller.
Solution Approach 2:
A central controller board acts as an intermediary between the individual LED modules and the power source/control system. The controller board receives signals from each LED module through standardized connectors and distributes control signals and power accordingly. This intermediary structure simplifies the overall connection architecture by providing a centralized interface point rather than requiring direct connections from each LED to the control system.
2Ease of operation
If each LED is individually connected to the controller for precise control, then the controller can manage each light independently, but the assembly process becomes time-consuming and complicated
Solution Approach 1:
LEDs are grouped into modules with each module containing multiple LEDs that can be controlled independently or together. Each module is pre-assembled with its own circuit board and connectors, allowing the module to be treated as a single unit during assembly. This maintains control precision at the module level while dramatically simplifying the assembly process compared to individual LED connection.
Solution Approach 2:
Multiple LEDs within each module are electrically combined on a shared circuit board, allowing them to be controlled as a group while still maintaining the ability to address individual LEDs through the module interface. The module itself is then combined with other modules through standardized connectors, reducing the number of separate connection operations required during assembly.
3Adaptability or versatility
If LEDs are arranged in radial positions facing different directions, then the beacon provides omnidirectional signaling capability, but the positioning and connection of each LED becomes more difficult
Solution Approach 1:
The radial LED array is segmented into multiple modules, each handling a specific angular sector. Within each module, LEDs are positioned at precise radial angles relative to the module's center, which is easier to achieve than positioning all LEDs radially around a central point. The modules themselves are then arranged radially around the controller board, with each module's orientation providing the desired omnidirectional coverage.
Solution Approach 2:
Instead of positioning all LEDs in a single radial plane around the controller, the solution uses multiple modular units that can be stacked or arranged in three-dimensional space. Each module maintains precise radial positioning of its internal LEDs, while the modules themselves are positioned at different angular positions around the controller, achieving omnidirectional coverage through spatial distribution rather than complex two-dimensional radial layout.

AI summary
A signal lighting beacon for a vehicle has a base and a plurality of LED arrays mounted on the base. the LED arrays are arranged to direct light signals outward in multiple different radial directions. Each LED array has an LED array circuit board having plurality of LEDs and an electrical connector mounted thereon. A common circuit board is connected to each of the plurality of LED arrays by electrical connectors on the common circuit board. The electrical connectors of single-sided LED circuit boards can be substantially identical to the electrical connectors on a single-sided common circuit board disposed at an angle relative to the LED circuit boards. The connectors can be connected to one another by inserting spade terminals into corresponding sockets from the sides of the sockets. The LED arrays can be pivoted relative to the common circuit board without withdrawing the spade terminals from the sockets.
