Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural sliding bearings suffer from increased wear due to dust and dirt accumulation, require complex structures, and are costly and maintenance-intensive, especially when subjected to high forces and external influences like earthquakes.
Innovation Solution
A structural sliding bearing with a primary sliding surface composed of two angled partial sliding surfaces that combine vertical and horizontal force transfer, eliminating the need for guiding rails and allowing for a gap-free design, using low-friction, permanently lubricated materials to facilitate smooth movement and reduce wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional structural sliding bearings use guiding rails and complex structures to ensure stability and force transfer, then reliability is improved, but device complexity increases and manufacturing costs increase
Solution Approach 1:
The patent combines multiple functions (guiding, force transfer, and sliding) into a single planar sliding surface with an angled geometry. The sliding surface is configured at an angle between 0-45 degrees relative to the sliding plate, enabling it to simultaneously handle vertical loads, horizontal forces, and provide guidance, thereby eliminating the need for separate guiding rails while maintaining reliability
Solution Approach 2:
The angled sliding surface serves multiple purposes: it transfers vertical forces from the superstructure, resists horizontal forces (such as earthquake or wind loads), and provides uniaxial guidance along the inclined plane. This multi-functional design replaces traditional multi-component systems with a single integrated bearing structure
2Reliability
If traditional structural sliding bearings accumulate dust and dirt in complex structures, then durability deteriorates, but manufacturing costs increase due to maintenance requirements
Solution Approach 1:
The patent extracts and eliminates the guiding rail component from the bearing system, replacing it with a simplified planar sliding surface. This removal of complex internal structures eliminates the spaces and crevices where dust and dirt would accumulate, resulting in a cleaner, more durable bearing that requires less maintenance
Solution Approach 2:
The patent changes the geometric parameters of the sliding surface by introducing an inclination angle between 0-45 degrees. This angular configuration alters the surface characteristics to prevent dust accumulation while maintaining effective force transfer and sliding functionality, thereby improving durability
3Reliability
If structural sliding bearings are designed with gap-free sliding surfaces to prevent uneven wear, then manufacturing precision increases, but device complexity increases
Solution Approach 1:
The patent merges the gap prevention mechanism into the basic geometry of the sliding surface itself. By configuring the sliding surface as a continuous planar interface at an inclination angle, the design inherently prevents gaps without requiring additional precision-machined features or complex assembly tolerances, making the gap-free condition achievable through standard manufacturing practices

AI summary
The present invention relates to a structural sliding bearing 210 for connecting a first structure part to a second structure part. The structural sliding bearing 210 has a bearing base 212 connectable to the first structure part, a sliding plate 216 connectable to the second structure part, and an intermediate bearing part 214 disposed between the bearing base 212 and the sliding plate 216, wherein a primary sliding surface 226 of the structural sliding bearing 210 is disposed between the intermediate bearing part 214 and the sliding plate 216. The primary sliding surface 226 has at least two partial sliding surfaces 228A and 228B, each arranged in sliding planes 230A and 230B angled relative to one another, the sliding planes 230A and 230B meeting at a common line of intersection S that forms an axis of movement A of the structural sliding bearing 210 along which the sliding plate 216 can move. The two sliding planes 230A and 230B include a first angle α, the first angle α being selected such that no gap occurs in the area of the primary sliding surface 226 when the structural sliding bearing 210 is in use. Furthermore, the invention relates to a structural bearing system 700 in which the advantageous principle of the structural sliding bearing 210 is applied.
