Solution Overview
Problem
Industrial water jetters face a dilemma after ten years of operation, where either maintaining an aging carrier vehicle with increasing costs or replacing the entire system is expensive, and environmental regulations reduce the lifespan and usage areas of carrier vehicles.
Innovation Solution
A modular functional assembly for water jetters, comprising two adaptable functional modules and subframes that can be easily fixed to different carrier vehicle chassis, allowing the functional equipment to be transferred to new vehicles, reducing downtime and maintenance costs while meeting evolving environmental standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the carrier vehicle is kept beyond ten years of operation, then the hydro-cleaner can continue to be used, but maintenance and repair costs increase and downtime increases
Solution Approach 1:
The hydro-cleaner system is divided into two separable parts: the functional equipment (tanks, pumping system) and the carrier vehicle. The functional equipment is mounted on removable sub-frames that can be detached from the carrier vehicle, allowing the functional equipment to be independently maintained or transferred to a new carrier vehicle while the old carrier vehicle can be replaced or repaired separately.
Solution Approach 2:
The sub-frames are designed to be adaptable to different carrier vehicle chassis, enabling the same functional equipment to be mounted on various carrier vehicles. This universality allows the functional equipment to remain in service by being transferred to a new carrier vehicle when the old one reaches the end of its service life or requires extensive repairs.
2Reliability
If the entire hydro-cleaner system is replaced with a new one, then reliability and performance are improved, but cost increases significantly
Solution Approach 1:
The system is segmented into replaceable functional modules mounted on sub-frames, allowing only the carrier vehicle to be replaced while retaining the valuable functional equipment (tanks, pumping system). This selective replacement significantly reduces the cost compared to replacing the entire integrated system.
Solution Approach 2:
When the carrier vehicle reaches the end of its service life or requires replacement, the functional equipment is recovered by detaching it from the old carrier vehicle and mounting it on a new carrier vehicle. This recovery of functional equipment avoids the cost of replacing the entire system.
3Stability of the object's composition
If the functional equipment is fixed permanently to the carrier vehicle, then structural stability is maintained, but adaptability to different carrier vehicles is lost
Solution Approach 1:
The mounting system transitions from a fixed permanent connection to a dynamic removable connection. The sub-frames are designed with attachment and detachment capabilities, allowing the functional equipment to be securely mounted when needed (providing structural stability during operation) and easily removed or transferred to different carrier vehicles when required.
4Ease of manufacture
If the subframes are made rigid and fixed in size, then manufacturing simplicity is maintained, but adaptability to different chassis widths is reduced
Solution Approach 1:
The sub-frames incorporate adjustable elements such as telescopic cross members that can change length to accommodate different chassis widths. This dynamic adjustment capability allows the same sub-frame design to adapt to various carrier vehicle configurations while maintaining relatively simple manufacturing processes compared to creating multiple fixed-size sub-frame variants.

AI summary
- Functional assembly of a hydro-jetting unit comprising two functional modules and two subframes adaptable to different chassis of carrier vehicles.- The hydro-jetting unit (1) comprises a carrier vehicle (2) equipped with a chassis (3), and a functional assembly (4) which is removably attached to said chassis (3) of the carrier vehicle (2). The functional assembly (4) comprises two functional modules (9A, 9B) including all the functional equipment, namely a first functional module (9A) equipped with at least one tank (8) and a second functional module (9B) equipped with at least one pumping system, as well as two subframes (10A, 10B). Each of the functional modules (9A, 9B) is capable of being attached to one of these subframes (10A, 10B). Each of these subframes (10A, 10B) is adaptable to different carrier vehicle chassis and is adapted to the chassis (3) of the carrier vehicle (2) on which it is intended to be mounted, thus allowing, in particular, for quick installation and removal of the assembly. functional (4).
