Large to medium-size sweeping and mopping vehicle and mopping vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior mopping vehicles are ineffective in collecting ground solid refuse and have a large turning radius, making them inflexible and unable to clean corner areas effectively.
Innovation Solution
A large to medium-size sweeping and mopping vehicle equipped with a disc-type sweeping mechanism, a round-roller-type sweeping mechanism, and a mopping mechanism, featuring a clean water tank, refuse collector, and a washing water tank, which allows for efficient collection and cleaning of solid refuse and dust, including corner areas, through a combination of sweeping and mopping systems assisted by a water spraying system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a prior mopping vehicle is used, then the vehicle can clean road surfaces, but it cannot effectively collect ground solid refuse
Solution Approach 1:
The patent combines a mopping mechanism with a sweeping mechanism into a single vehicle. The sweeping mechanism includes a round roller with sweeping brushes that can collect solid refuse, while the mopping mechanism includes a mop that can clean road surfaces. This merging allows the vehicle to perform both functions simultaneously, resolving the contradiction between refuse collection capability and cleaning effectiveness.
Solution Approach 2:
The vehicle is designed with multi-functional capabilities by integrating both sweeping and mopping systems. The round roller can sweep solid refuse into a collection container, while the mop can wet-mop the road surface. This universal design enables the single vehicle to handle multiple cleaning tasks that previously required separate equipment, thereby improving both refuse collection and overall cleaning effectiveness.
2Adaptability or versatility
If a prior mopping vehicle is used, then the vehicle can operate on road surfaces, but it has a large turning radius and cannot clean corner areas
Solution Approach 1:
The vehicle body is segmented into multiple independent functional modules: the sweeping mechanism with round roller, the mopping mechanism with mop, and the water tank system. These segmented modules can be independently controlled and positioned, allowing the vehicle to navigate tight corners and access areas that would be inaccessible to a monolithic vehicle design. The segmentation enables better maneuverability and adaptability to various cleaning scenarios.
3Productivity
If a sweeping mechanism is added to collect solid refuse, then refuse collection improves, but the vehicle structure becomes more complex
Solution Approach 1:
The sweeping brushes are nested within the round roller structure, and the mop is nested within the mopping mechanism assembly. The water tank is positioned to nest with other vehicle components. This nested arrangement allows multiple functional elements to be compactly integrated without significantly increasing the overall vehicle footprint or structural complexity, while still providing comprehensive sweeping and mopping capabilities.
