Solution Overview
Problem
Multi-purpose vehicles require a suction device that can be easily adapted for various applications without compromising efficiency or requiring extensive reconfiguration.
Innovation Solution
A suction vehicle design featuring a permanently mounted suction fan, suction line, and base unit, with a decouplable adapter unit that allows for easy exchange of suction ports and outlet ports, enabling the suction nozzle to be adapted for different applications by sliding the adapter unit sideways at angles between 45° and 135° to the main direction of travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction device is permanently mounted on the suction vehicle, then the suction efficiency and reliability are maintained, but the adaptability to different applications is reduced
Solution Approach 1:
The suction mouth is divided into a base unit that remains permanently mounted and an adapter unit that can be exchanged. The base unit contains the suction fan and suction line, while the adapter unit includes the suction opening and adapter outlet opening. This segmentation allows the permanent mounting of core suction components for reliability while enabling easy exchange of adapter units for different applications.
Solution Approach 2:
The base unit is designed as a universal platform that can accommodate multiple different adapter units for various applications such as sweeping, scrubbing, and mowing. The standardized coupling interface between the base unit and adapter units enables one permanent structure to serve multiple functions across different cleaning applications.
2Adaptability or versatility
If the entire suction mouth is made exchangeable, then the adaptability to different applications is improved, but the device complexity and assembly effort are increased
Solution Approach 1:
The suction mouth is segmented into a permanent base unit and an exchangeable adapter unit. Only the adapter unit needs to be exchanged for different applications, while the base unit remains fixed. This reduces the complexity of exchange operations compared to exchanging the entire suction mouth assembly.
Solution Approach 2:
The base unit permanently combines the suction fan, suction line, and coupling interface into a single integrated assembly. This merging of core components into a permanent unit simplifies the exchange process, as only the lighter adapter unit needs to be removed and replaced rather than the entire suction system.
3Adaptability or versatility
If the adapter unit is exchanged for different applications, then the adaptability is improved, but the loss of time for exchange operations occurs
Solution Approach 1:
The suction mouth is divided into a permanent base unit and an exchangeable adapter unit. Only the adapter unit needs to be exchanged for different applications, significantly reducing the time required compared to exchanging the entire suction assembly. The lightweight adapter unit can be quickly removed and replaced.
Solution Approach 2:
Multiple adapter units for different applications can be pre-prepared and stored on the vehicle. The standardized coupling interface allows for quick connection without requiring complex alignment or adjustment procedures, minimizing exchange time.
4Adaptability or versatility
If the suction flow direction is changed for different applications, then the adaptability is improved, but the device complexity is increased
Solution Approach 1:
The suction mouth is segmented into a base unit with the suction fan and an adapter unit with different outlet opening orientations. Each adapter unit is designed with a specific outlet orientation suitable for its application, allowing the suction flow direction to be changed by simply exchanging the adapter unit rather than modifying the base unit or adding complex flow control mechanisms.

AI summary
A vacuum cleaner, in particular a vacuum vehicle, comprises a suction blower, a suction line (17), and a suction nozzle for directing a suction flow. The suction nozzle has a base unit (23) and an adapter unit (22) arranged on the base unit (23). The adapter unit (22) comprises a suction opening (24) and an adapter outlet opening and can be decoupled from the vacuum cleaner and the base unit (23). The vacuum cleaner is designed such that the suction flow passes through the suction opening (24) into the adapter unit (22), from the adapter unit (22) through the adapter outlet opening into the base unit (23), and through the suction line (17).
