Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled road construction machines face challenges in simplifying the assembly, maintenance, and repair of their lighting systems, which are often integrated into vehicle paneling or frames, leading to complex installations and increased risk of damage from environmental factors.
Innovation Solution
The integration of lighting equipment into a self-supporting hollow body made of plastic, allowing for preassembly as a unit and easy installation, with features like recesses for headlights and signal lamps, and integrated electrical connections, along with the option of using fiber-reinforced materials for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If lighting equipment is integrated into vehicle paneling or frame parts, then the lighting system is structurally integrated, but the assembly, maintenance and repair become complex and time-consuming
Solution Approach 1:
The lighting equipment is separated from the vehicle paneling and frame parts, and integrated into an independent hollow body module. This segmentation allows the lighting system to be manufactured, assembled, maintained, and repaired as a separate unit, significantly reducing complexity and time requirements while maintaining structural integration through the modular design.
Solution Approach 2:
The lighting equipment is nested within the hollow body, which itself is integrated into the vehicle structure. This nested arrangement allows the lighting system to be structurally integrated while remaining contained in a separate, accessible module that can be easily removed and replaced without disassembling the entire vehicle structure.
2Strength
If lighting equipment is arranged on metal traverse, then structural strength is provided, but the risk of damage from impacts and environmental factors increases
Solution Approach 1:
The hollow body is made from a plastic material that provides both structural strength and impact resistance. This plastic housing acts as a protective shell that absorbs and distributes impact forces, reducing the risk of damage to the lighting equipment inside while maintaining the necessary structural strength for vehicle integration.
Solution Approach 2:
The hollow body can be constructed from composite materials that combine the strength benefits of rigid structures with the impact resistance and environmental protection of plastic materials. This composite approach provides both the structural strength needed for vehicle integration and protection against impacts and environmental factors.
3Illumination intensity
If the traverse is positioned low for optimal lighting coverage, then lighting effectiveness is improved, but the risk of contact with obstacles on construction sites increases
Solution Approach 1:
The plastic hollow body provides a protective enclosure that allows the lighting equipment to be positioned at an optimal height for lighting coverage while protecting it from obstacles. The hollow body's material properties absorb minor impacts from construction site obstacles, enabling better positioning without proportionally increased damage risk.
