Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile high-pressure cleaning devices lack mechanical stability and efficient assembly processes, with electrical components often requiring complex wiring and limited storage for electrical parts, which increases production costs and assembly complexity.
Innovation Solution
The design integrates a holding part that serves as both a motor mount and an electrical box with a storage compartment, featuring a cover that can pivot to facilitate access and wiring of electrical components, along with a hood that allows for easy maintenance and a large storage compartment to accommodate multiple electrical parts, enhancing mechanical stability and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If electrical parts are arranged in a separate electrical box, then wiring complexity increases and assembly complexity increases, but mechanical stability is improved
Solution Approach 1:
The patent combines the electrical box function with the holding part structure. The holding part includes a receiving compartment that houses both the motor and electrical parts, eliminating the need for a separate electrical box. This integration reduces assembly complexity while maintaining mechanical stability through the unified structural design.
Solution Approach 2:
The holding part serves multiple functions: it holds the motor, provides structural support, and contains the electrical parts within its receiving compartment. This multi-functionality eliminates the need for separate dedicated electrical box structures, simplifying assembly while maintaining mechanical integrity.
2Stability of the object's composition
If a fixed cover is used on the electrical box, then mechanical stability is improved, but ease of operation deteriorates due to limited access
Solution Approach 1:
The cover on the holding part is designed to be movable rather than fixed. It can be opened to provide access to the electrical parts and control elements, then closed to maintain mechanical stability. This dynamic design allows the structure to transition between stable and accessible states as needed.
Solution Approach 2:
The holding part structure has different properties in different regions: the main body provides rigid structural support, while the cover portion provides localized accessibility. This spatial differentiation of properties allows simultaneous achievement of mechanical stability and ease of operation.
3Device complexity
If the storage compartment is made larger to accommodate more electrical parts, then device complexity is reduced, but the area occupied increases
Solution Approach 1:
The electrical parts and control elements are nested within the receiving compartment of the holding part, which itself is integrated into the overall device structure. This nesting arrangement consolidates multiple components into a compact configuration, reducing the total area occupied while accommodating all necessary electrical parts.
Solution Approach 2:
The holding part utilizes vertical space with side walls that extend upward, creating a three-dimensional storage volume rather than a simple horizontal expansion. This dimensional approach allows accommodation of electrical parts without proportionally increasing the footprint area.

AI summary
The invention relates to a mobile high-pressure cleaning device (10) comprising an undercarriage that has a receiving portion (25) arranged on its upper side, said receiving portion forming a motor holder (23) into which a motor (22) for driving a pump is inserted, and a holding portion (60) which secures said motor (22) in the motor holder (23) being placed on said receiving portion (25) and having a receiving compartment (67) on its upper side, for electric parts. To improve the high-pressure cleaning device such that it has a structurally simpler and more mechanically resilient design, it is suggested that the holding portion (60) is designed as a hollow body comprising a main part (61) and a cover (65) mounted on said main part (61), the main part (61) forming the receiving compartment (67) with a base wall (69) that overlaps the motor (22) and side walls (71, 72, 73, 74) that protrude upwards therefrom, and said cover (65) being able to be moved back and forth between a closed position and an open position and carrying, on its outer side, at least one actuator for an electric control element.
