Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warning devices for rear-end collisions lack stability and convenience due to reliance on unstable rollers and complex structures, posing safety risks during placement and occupation of space.
Innovation Solution
A self-propelled warning device with a motor-driven mechanism, including wheels and supporting units that allow the device to move and stabilize upright, featuring a cylindrical base with receiving and rotating slots for supporting poles, enabling efficient deployment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rollers are used to support the warning device, then the device can be moved, but the stability of the warning device deteriorates
Solution Approach 1:
The patent employs dynamic transformation of the supporting structure from a mobile configuration (on rollers) to a stable configuration (on wheels with supporting poles). The supporting poles can be extended to contact the ground, transforming the device from a rolling state to a stationary supported state, thus resolving the contradiction between mobility and stability.
Solution Approach 2:
The supporting structure is divided into separate functional components: rollers for movement, wheels for positioning, and supporting poles for stabilization. This segmentation allows each component to perform its specific function optimally - rollers enable easy movement, while the extended supporting poles provide stable support when deployed.
2Ease of manufacture
If a complex structure is used to connect the roller and body, then the connection can be achieved, but the space occupation increases and convenience of storage deteriorates
Solution Approach 1:
The supporting poles are designed to be storable within the body or frame of the warning device when not in use. This nesting arrangement allows the complex supporting structure to be compacted into a small volume during storage and transport, while still providing full functionality when deployed.
Solution Approach 2:
The supporting poles are designed with dynamic deployment capability, allowing them to be quickly extended from a compact stored position to a fully extended support position. This dynamic transformation enables the structure to transition between compact storage and full functional deployment, reducing space occupation during transport.

AI summary
A warning device used for road safety includes a warning sign and a driving mechanism. The driving mechanism includes a base, a driving unit, at least one wheel, a plurality of supporting units, and a plurality of driving members. The driving unit is accommodated in the base. The at least one wheel is connected to and driven by the driving unit. The plurality of supporting units are movably connected to the base. The plurality of driving members can manipulate the supporting units. Each of the supporting units is movable between a receiving or retracted position and a supporting or extended position. For stability in placement, the device can be lifted a small distance above the road by the supporting units when these are deployed. The driving mechanism is also disclosed.
