Load Warning Flag and LED Clamp for Overhanging Cargo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing makeshift solutions for marking overhanging loads on vehicles, such as red rags or plastic tape, often fail to meet regulatory requirements for flag size and visibility during twilight and evening hours, posing a risk of accidents and injuries due to inadequate load marking.
Innovation Solution
A safety device comprising a supporting member with a lamp casing and a flag-supporting arrangement, featuring a brightly colored flag and an LED flashing unit, which can be securely attached to loads using screws, bungee cords, or magnets, ensuring compliance with safety codes by providing both a visible flag and a rear/side visible light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If makeshift solutions like red rags or plastic tape are used to mark overhanging loads, then the device complexity is reduced and ease of operation is improved, but the reliability of meeting legal requirements and safety warning effectiveness deteriorates
Solution Approach 1:
The patent combines multiple safety functions into a single integrated device: a flag assembly, lamp assembly, and supporting member with attachment means are merged into one unit. This resolves the contradiction by providing a device that is both easy to operate (single unit attachment) and reliable (meets all safety requirements for flags, lights, and secure mounting).
Solution Approach 2:
The safety device performs multiple functions simultaneously: it displays a flag during daytime, emits light during twilight and evening, and provides secure attachment to the load. This multi-functionality ensures compliance with varying safety requirements across different lighting conditions while maintaining ease of operation through a single integrated solution.
2Reliability
If a properly sized flag and lighting system are used to meet legal requirements, then the reliability of safety warning is improved, but the device complexity and ease of operation worsen
Solution Approach 1:
The patent integrates the flag assembly, lamp assembly, battery, and attachment mechanisms into a single unified structure. This merging reduces device complexity by eliminating the need for separate components while maintaining all necessary safety functions for reliable warning effectiveness.
Solution Approach 2:
The integrated supporting member serves multiple functions: structural support for the flag, mounting for the lamp assembly, attachment to the load, and housing for the battery. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while ensuring reliable safety warning through proper flag size and lighting.
3Reliability
If a permanently fixed safety device is used on the vehicle, then the reliability of continuous safety warning is improved, but the adaptability to different loads and ease of operation deteriorates
Solution Approach 1:
The patent employs detachable attachment means (screws, bungee cords, or magnets) that allow the safety device to be dynamically attached and removed from different loads. This dynamic attachment system provides adaptability to various load types and configurations while maintaining reliability through secure attachment during transport.
Solution Approach 2:
The supporting member is designed with universal attachment capabilities that work with different load types (wood, metal, plastic) through multiple attachment methods. This universality ensures the device can be reliably attached to any load while maintaining ease of operation for different loading scenarios.
