Chassis Attachment Mechanism for Universal Functional Part Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technical facilities face challenges in universally transferring and attaching functional parts, such as sealing tools, due to limited floor space and varying tool sizes, as conventional chassis designs require floor-level attachment and cannot adapt to different device heights.
Innovation Solution
A chassis with adjustable height wheels and suspension eyes that attach to stop elements on the technical device via bolts, allowing for secure and quick attachment above the floor, enabling universal compatibility with various technical devices and maintaining stability through contact elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional chassis with floor-level attachment sections is used, then the chassis can be attached to technical devices, but it cannot be used when there is no free space in the floor area
Solution Approach 1:
The patent transitions the attachment interface from the horizontal floor plane to the vertical side surface of the technical device. The chassis now attaches to protruding stop elements on the side surface rather than requiring floor-level sections, effectively moving the attachment dimension from 2D floor space to 3D vertical space utilization.
Solution Approach 2:
Instead of the chassis having attachment sections on its underside that contact the floor, the invention inverts the approach by having the chassis with protruding attachment elements on its upper side that engage with stop elements on the technical device. This reversal eliminates the need for floor-level clearance.
2Adaptability or versatility
If the chassis is designed for universal attachment, then it can be assigned to various technical devices, but the attachment process may become complex
Solution Approach 1:
The patent implements universal attachment by equipping all chassis with identical protruding attachment elements and all technical devices with corresponding stop elements. This standardized interface allows the same chassis design to be attached to various technical devices without customization, achieving multi-functionality through standardization.
Solution Approach 2:
The attachment system is segmented into two independent components: protruding elements on the chassis and corresponding stop elements on the technical device. This segmentation allows each component to be designed and manufactured separately with simple geometries, reducing overall system complexity while maintaining universal compatibility.
3Productivity
If the gripping elements are designed for quick attachment, then tool changes are faster, but the connection may be less secure
Solution Approach 1:
The protruding attachment elements are pre-positioned and pre-oriented on the chassis before attachment. The stop elements on the technical device are also pre-configured at appropriate heights and positions. This preliminary preparation allows for rapid engagement without complex alignment procedures, maintaining both speed and security.
Solution Approach 2:
The attachment system uses simple geometric intermediaries (protruding elements and stop elements) that facilitate quick connection through basic engagement mechanics. These intermediary components translate the requirement for quick attachment into a simple insert-and-lock motion that inherently provides secure connection without requiring complex fastening mechanisms.

AI summary
The arrangement has a chassis which supports a functional part receiving device (2) and includes impact units arranged in a technical device. Connection lugs (4) engage with the impact units and are arranged in an upper section of the chassis. The impact units are designed as projections, and the connection lugs make the projections. The chassis has wheels (6), where the wheels are accommodated on the chassis.
