Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profiled bearings for rails require time-consuming installation and can experience jumping of clamping sections, especially when handling heavy loads, due to the need for two clamping sections and inadequate frictional engagement.
Innovation Solution
A profiled bearing design with a single clamping section featuring resilient and dimensionally stable clamping legs, a clamping finger, and a wedge effect to securely engage the rail, preventing jumping and ensuring a tight fit through enhanced frictional engagement and a simplified installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two profiled clamping sections are used to fix the rail, then the rail can be secured in the profiled bearing, but the installation becomes time-consuming and the clamping sections may jump out during operation
Solution Approach 1:
The patent combines two separate clamping functions into a single integrated profiled clamping section. This single component includes both a first clamping leg for initial engagement and a second clamping leg for final securing, eliminating the need for two separate clamping sections and reducing installation time while maintaining secure fixing.
Solution Approach 2:
The profiled clamping section is segmented into functionally distinct parts: a first clamping leg with a first clamping surface for initial engagement, and a second clamping leg with a second clamping surface for final securing. This segmentation allows each part to perform its specific function efficiently within a single component.
2Reliability
If two profiled clamping sections are installed, then the rail can be clamped, but the second clamping section may jump out of position during installation
Solution Approach 1:
The first clamping leg performs a preliminary clamping action by engaging the rail with its first clamping surface before the second clamping leg is fully installed. This preliminary engagement stabilizes the rail position and prevents the second clamping section from jumping out during installation.
Solution Approach 2:
The first clamping leg acts as an intermediary element that provides initial stabilization of the rail, facilitating the subsequent installation of the second clamping leg without causing positioning issues.
3Strength
If heavy loads are moved on the rail system, then the rail must be securely fixed, but the profiled clamping sections may jump out under load
Solution Approach 1:
The profiled clamping section is designed to be resilient and capable of dynamic adjustment. The clamping legs can elastically deform to accommodate load variations while maintaining continuous contact with the rail, preventing jump-out under heavy loads while still bearing significant weight.
Solution Approach 2:
The clamping force parameters are dynamically adjusted through the resilient design of the clamping legs, which can increase their gripping force in response to applied loads, ensuring the rail remains securely fixed even under heavy loading conditions.
4Ease of operation
If a single profiled clamping section is used, then installation is simplified, but adequate frictional engagement may not be achieved
Solution Approach 1:
Different regions of the single profiled clamping section have specialized surfaces optimized for specific functions: the first clamping surface is designed for initial engagement with specific friction characteristics, while the second clamping surface is designed for final securing with enhanced frictional engagement properties.
Solution Approach 2:
The profiled clamping section incorporates multiple material properties and surface characteristics in different regions, combining resilient materials for the clamping legs with dimensionally stable materials for the base, creating a composite structure that achieves both ease of installation and adequate frictional engagement.

AI summary
A profiled bearing for a rail and a rail system are disclosed. The profiled bearing has a profiled base with a first lateral wall, a second lateral wall, and a base which connects a first end of the first lateral wall to a first end of the second lateral wall, and the profiled bearing also has a profiled clamping section. The base and the lateral walls form a receiving pocket for receiving the rail. In a functional position, the profiled clamping section is clamped in a gap between the rail inserted into a bearing bed of the base and the second lateral wall. A clamping finger which extends in the direction of the second lateral wall is molded in the region of a second end of the first lateral wall, the end being arranged at a distance from the base, wherein the rail can be pressed into the bearing bed by means of the clamping finger, and the profiled clamping section has a base web with two clamping limbs which extend from one face of the base web and which can be pressed into the gap between the rail inserted into the bearing bed and the second lateral wall. The clamping limbs of the profiled clamping section extend in the direction of the bearing bed in the functional position in which the clamping limbs are inserted into the gap, and a first clamping limb lies against the rail at least in some regions and a part of a second clamping limb is pressed into an undercut formed on the second lateral wall.
