Integrated Guide Rail Design for Simplified Assembly and Cost Reduction
Here’s PatSnap Eureka !
Summary
Problems
Conventional adjusting devices for vehicle parts require complex and costly assembly processes, including separate fastening brackets that increase material and assembly costs, and complicate the connection process, especially during crash conditions where additional support is needed.
Innovation solutions
The use of structurally separated supporting parts welded directly to the guide rail, which are designed to provide secure support and reduce material and assembly costs by eliminating the need for screw connections and simplifying the assembly process, while maintaining a tight connection capable of handling large load forces.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a fastening bracket with screw connections is used to connect the adjusting mechanism to the guide rail, then the connection provides secure support under load, but the assembly process becomes complex and costly
Why choose this principle:
The patent merges the fastening bracket and the guide rail into a single integrated component. The guide rail is designed with built-in supporting parts that directly support the adjusting mechanism, eliminating the need for separate fastening brackets and screw connections. This integration simplifies the assembly process while maintaining connection integrity through the unified structural design.
Principle concept:
If a fastening bracket with screw connections is used to connect the adjusting mechanism to the guide rail, then the connection provides secure support under load, but the assembly process becomes complex and costly
Why choose this principle:
The patent extracts the fastening bracket as a separate component and eliminates it from the assembly. Instead, the guide rail itself is designed to provide the supporting function directly through integrated supporting parts, removing the unnecessary intermediate fastening element and simplifying the overall structure.

Abstract
An adjusting device for adjusting two vehicle parts relative to each other is provided. The adjusting device comprising a first guide rail, which is longitudinally extended along a longitudinal axis and which is formed by a base and lateral legs connected to the base, a second guide rail, which is movably arranged on the first guide rail and which is longitudinally extended along the longitudinal axis, an adjusting mechanism, which is arranged between the legs on the first guide rail and which comprises a spindle nut, which can be rotated about the longitudinal axis in order to drive the adjusting device, a spindle, which is arranged in a rotationally fixed manner on the second guide rail and which is longitudinally extended along the longitudinal axis and which engages with the spindle nut in such a way that, when the spinal nut is rotated, the first guide rail is moved along the longitudinal axis relative to the second guide rail, and a fastening device for fastening the adjusting mechanism to the first guide rail.
