Stackable Traffic Light Modules with Gear Ring Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic lights with modular configurations face challenges in maintaining structural rigidity and flexibility in module orientation, as the structural integrity is often compromised by the direct fixation of casings, limiting modularity and adaptability.
Innovation Solution
Incorporating an inner core with gear rings for axial coupling and centering devices, along with fixing means like threaded sleeves and locknuts, to form a rigidizing column that supports the casings and allows for modular assembly with variable orientation and interchangeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If casings are fixed directly between one another to form the traffic light assembly, then the assembly can be constructed with modular modules, but the structural rigidity of the assembly is compromised
Solution Approach 1:
The traffic light assembly is divided into modular units, each comprising a casing and an inner core. The inner core acts as a separate structural component that segments the functional elements (signaling means) from the structural support, allowing independent optimization of modularity and structural integrity.
Solution Approach 2:
The inner core serves as an intermediary structural element between the casings. Instead of casings being directly fixed to each other, they are attached to the inner core, which mediates the structural connection and provides the rigidifying column that enhances overall assembly rigidity while preserving modular configuration.
2Adaptability or versatility
If modules are made interchangeable with variable orientation for flexibility, then adaptability is improved, but assembly stability may be compromised
Solution Approach 1:
The inner core features asymmetric attachment points or mounting interfaces that allow casings to be secured in specific angular positions. This asymmetric design enables controlled orientation flexibility while maintaining stable, predetermined assembly configurations when modules are installed.
Solution Approach 2:
The inner core provides universal mounting capability for different casing types and orientations through standardized attachment interfaces. This allows the same inner core structure to support multiple module configurations and orientations while maintaining stable assembly through consistent structural principles.
