Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver's cab stabilizers for commercial vehicles have complex and costly assembly interfaces due to multiple surfaces that require precise alignment, making the assembly process labor-intensive and expensive.
Innovation Solution
A driver's cab stabilizer design featuring two parallel levers extended by connecting elements, with a torsion bar spring indirectly connected to the levers, and an assembly interface formed by two plane separations that simplify assembly by reducing the number of surfaces to be machined and allowing for easier disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple surfaces are used for the assembly interface between stabilizer levers and connecting elements, then full-surface contact is achieved for reliable connection, but manufacturing cost increases and production complexity increases due to the number of surfaces and low tolerances required
Solution Approach 1:
The assembly interface is segmented into exactly two plane separations instead of multiple surfaces, reducing the number of machining operations while maintaining connection reliability through the simplified separation geometry
Solution Approach 2:
The design changes the geometric parameters of the assembly interface from multiple surfaces with low tolerances to exactly two plane separations, reducing manufacturing complexity while achieving the same functional goal of secure connection
2Manufacturing precision
If multiple surfaces with low tolerances are used for the assembly interface, then full-surface contact is achieved, but assembly time increases and productivity decreases
Solution Approach 1:
The assembly interface is divided into exactly two plane separations, reducing the number of precision alignment operations required and thereby increasing assembly speed without sacrificing contact precision
Solution Approach 2:
The interface geometry is changed from multiple surfaces to two plane separations, reducing the degrees of freedom for alignment and making the assembly process faster while maintaining precise contact
3Strength
If the driver's cab stabilizer is designed as a single integrated component, then structural integrity is maximized, but assembly complexity increases and repairability decreases
Solution Approach 1:
The stabilizer is segmented into separate components (stabilizer levers and connecting elements) that are assembled together, reducing overall assembly complexity while maintaining structural integrity through the designed connection interface
Solution Approach 2:
The modular design allows individual components to be discarded or replaced independently during repair, improving repairability without compromising the structural integrity of the complete assembly
Applied Scientific Principles

AI summary
The invention relates to a driver's cab stabiliser (7) having: two levers (14) which extend parallel to each other in a longitudinal direction (x) of the vehicle and are each lengthened in the longitudinal direction (x) of the vehicle by a connecting element (16); and a torsion bar spring (8) which extends in a transverse direction (y) of the vehicle between the two connecting elements (16) and is fixedly connected at both ends (9) to the associated lever (14) indirectly via the associated connecting element (16), the driver's cab stabiliser (7) having an assembly interface (17) situated inside same to simplify assembly. The invention is characterised in that the assembly interface (17) is formed by a total of exactly two intrinsically planar partitions (17) which extend in the transverse direction (y) of the vehicle and run between the two connecting elements (16) and the levers (14) associated therewith.
