Solution Overview
Problem
Existing guide devices for movable elements, such as those in motor vehicles, face challenges in providing reliable and stable guidance due to play and instability between sliding surfaces and contact surfaces, which complicates manufacturing and functionality.
Innovation Solution
A guide device comprising a guide rail and a sliding body with pressable sliding surfaces, utilizing spring elements for stable engagement and a base body formed from plastics materials with multiple sliding points or lines, ensuring secure placement and reduced friction, and incorporating latching devices for multiple plane fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional guide devices are used without pressing devices, then the structure is simpler, but the guidance becomes unstable with play between sliding surfaces
Solution Approach 1:
The pressing device incorporates spring elements that dynamically adjust the pressing force between the sliding body and guide rail, allowing the system to maintain stable contact under varying operational conditions while eliminating play and instability in the guidance mechanism
Solution Approach 2:
The spring elements modify the contact pressure parameter between sliding surfaces, transforming the static contact into a dynamically adjustable pressurized contact that maintains optimal engagement without requiring overly complex structural arrangements
2Reliability
If multiple spring elements are added for stable engagement, then the guidance reliability improves, but the manufacturing complexity increases
Solution Approach 1:
The pressing device and latching device are merged into a single integrated assembly, where spring elements serve dual functions of maintaining sliding contact and enabling latching, thereby improving engagement stability without proportionally increasing manufacturing complexity
Solution Approach 2:
The spring elements are designed to perform multiple functions simultaneously: providing continuous pressing force for stable sliding engagement, enabling automatic latching when deflected, and allowing easy release through controlled deflection, thus achieving high reliability without adding separate dedicated components for each function
3Manufacturing precision
If sliding surfaces are pressed firmly onto contact surfaces, then guidance precision improves, but friction increases
Solution Approach 1:
The spring elements provide optimized pressing forces that maintain precise alignment between sliding surfaces and contact surfaces while controlling the contact pressure to minimize frictional losses, achieving the right balance between guidance precision and energy efficiency
