Solution Overview

Problem

Conventional assembly and repair devices for vehicles require a floor recess with a base plate, making it difficult to install them on unpaved surfaces such as mud or seabed, where digging a hole is not possible.

Innovation Solution

A cassette assembly device with a shoring wall and support elements, such as steel supports, that allows the cassette to be hung freely between sheet piling, eliminating the need for a fixed base plate and enabling installation on any surface by using spacer elements to level the shoring wall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a floor recess with a fixed base plate is used, then the assembly and repair device has stable support, but it cannot be installed on unpaved surfaces such as mud or seabed

Engineering Contradiction:
Improveinstallation surface compatibilityVSAvoidinstallation structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts and removes the base plate from the traditional floor recess structure. Instead of requiring a fixed base plate embedded in the ground, the cassette is designed to be supported directly by carrier elements that attach to the side walls, allowing installation on various surfaces including unpaved ground without digging a hole.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention transitions from a horizontal foundation-based support system to a vertical carrier element-based support system. The carrier elements are attached to the inner and/or outer wall of the longitudinal side walls and extend horizontally to rest on the shoring wall, changing the dimensional orientation of the support structure from vertical foundation to horizontal carrier element.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the cassette is hung freely between shoring walls using carrier elements, then installation on any surface is enabled, but additional support structures are required

Engineering Contradiction:
Improveinstallation surface compatibilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention merges the carrier elements with the cassette structure by attaching them to the inner and/or outer wall of the longitudinal side walls during manufacturing. This integration ensures that the carrier elements are pre-positioned and ready for installation, reducing on-site assembly complexity while enabling flexible installation on various surfaces.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If spacer elements are used to level the shoring wall, then the cassette can be installed on uneven surfaces, but the device complexity increases

Engineering Contradiction:
Improvesurface levelness toleranceVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spacer elements act as intermediary components between the shoring wall and the carrier elements. These spacers compensate for height differences and uneven surfaces, allowing the cassette to be installed on varying ground conditions without requiring precise leveling of the shoring wall itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Assembly and repair equipment (1) for vehicles, in particular construction and commercial vehicles, comprising a one- or multi-part cassette () made of steel or similar corrosion-resistant material with two longitudinal side walls (5), end walls (7) and a bottom (9), wherein at least the side walls (5, 7) each have an inner wall (11) and an outer wall (13) arranged at a distance therefrom, which define a cavity (15) for receiving a curable filling material, wherein several spaced-apart support elements (17) for suspending the cassette (3) on a retaining wall, in particular a sheet pile wall (19), are attached to the inner and/or outer wall (11, 13) of the longitudinal side walls (5).
