Chassis Connecting Shoe Integrating Supply Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current commercial vehicle chassis frames are vulnerable to damage for electrical and pneumatic lines, as well as fluid supply lines, due to their exposure on the underside, making them susceptible to damage from thrown stones or splashing water.
Innovation Solution
The chassis frame design integrates supply lines into the connecting shoes, which serve as both a structural element and a protective interface for these lines, using standardized hole patterns and integrated pipe sections to securely attach and protect them, while also providing additional structural support and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If supply lines are arranged on the underside of the chassis frame, then installation is simple and space is utilized efficiently, but the lines are vulnerable to damage from thrown stones or splashing water
Solution Approach 1:
The patent merges the protection function with the existing connecting shoes by integrating receiving areas directly into their structure. This allows the connecting shoes to serve dual purposes: structural connection and line protection, eliminating the need for separate protective elements while maintaining installation simplicity.
Solution Approach 2:
The connecting shoes act as intermediary structures that inadvertently provide protection to the supply lines. By positioning the lines within the receiving areas of the connecting shoes, the patent uses these structural elements as mediators between the lines and external damage sources.
2Reliability
If additional protective structures are added for supply lines, then line protection is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the protective function into the existing connecting shoe structure, merging two functions (structural connection and line protection) into a single component. This avoids adding separate protective structures that would increase device complexity.
Solution Approach 2:
The connecting shoes are designed with multi-functionality, serving both as structural connection elements and as protective housings for supply lines. This universal approach eliminates the need for dedicated protective components, reducing overall structural complexity.
3Reliability
If supply lines are integrated into connecting shoes, then line protection and structural integrity are improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the connecting shoe structure to include dedicated receiving areas for supply lines, allowing the lines to be integrated during the connecting shoe manufacturing process. This segmentation enables standardized production while maintaining the protective function.
Solution Approach 2:
The receiving areas for supply lines are pre-integrated into the connecting shoe design during manufacturing. This preliminary action allows the lines to be positioned and secured without requiring additional assembly steps, reducing manufacturing complexity despite the integrated design.

AI summary
The vehicle has a chassis frame (4) including a longitudinal carrier, which is connected by a transverse carrier. The longitudinal carrier and the transverse carrier are connected with each other by a connecting shoe (1). The frame is composed of a module (3), a front module (8) and a middle module (9). The connecting shoe includes a connecting element (15) e.g. pipe section, for connecting lines and components, which are connected with the chassis frame. The lines are guided at the chassis frame. The connecting shoe includes a bearing (13) for fastening a stabilizer.
