Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bearing arrangements for pivoted sashes, such as windows and doors, face challenges in achieving high stability and ease of assembly, with current designs often lacking in structural integrity and requiring complex assembly processes.
Innovation Solution
A bearing arrangement featuring a longitudinally displaceable slide with an angled web for creating or releasing a positive connection between the base and bearing parts, combined with a band-shaped slider arm and a locking spring element, which allows for secure engagement and disengagement with retaining bolts, and a locking device to ensure correct assembly and prevent accidental movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a positive locking connection is provided between the bearing part and base part, then stability is improved, but assembly complexity increases
Solution Approach 1:
The slider is pre-positioned in an assembly position where it is held by a locking spring element, allowing the bearing part to be mounted on the base part before the final locking action occurs. This preliminary positioning simplifies assembly by separating the mounting operation from the locking operation.
Solution Approach 2:
The slider transitions from a static locked state to a dynamic movable state during assembly, allowing it to be actuated by the drive rod fitting to move from the assembly position to the holding position, creating the positive locking connection between the bearing part and base part.
2Strength
If the slider is made longitudinally displaceable with angled web, then load-bearing capacity is improved, but device complexity increases
Solution Approach 1:
The slider features an angled web instead of a symmetric design, with the angle specifically optimized to maximize load-bearing capacity during operation. The asymmetric geometry allows the web to be loaded at its maximum extent, improving strength while maintaining a relatively simple single-piece structure.
Solution Approach 2:
The slider arm is designed as a band-shaped element that extends in a direction transverse to the closing direction of the sash, adding a dimensional aspect that enhances stability and load distribution without significantly increasing overall complexity.
3Reliability
If locking spring element and detent spring element are used, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking spring element automatically engages the slider in the assembly position during installation, and the detent spring element automatically engages behind the web edge in the holding position to prevent accidental movement. These self-acting spring elements improve reliability without requiring external control mechanisms.
Solution Approach 2:
The spring elements utilize elastic deformation and force parameters to create reliable locking and detent actions. The locking spring element provides frictional locking in the assembly position, while the detent spring element provides mechanical engagement in the holding position, using spring force parameters to ensure reliable operation.
4Strength
If the web is loaded at maximum extent, then strength is improved, but stress on components increases
Solution Approach 1:
The angled web is designed with specific geometry that allows it to be loaded at its maximum extent during normal operation, optimizing strength utilization. The angle and dimensions are configured so that the web experiences optimal stress distribution that maximizes its load-bearing capability.
Solution Approach 2:
The bearing assembly design anticipates the high forces that will act on the web during operation, and the retaining bolts and slot receptacle configuration are designed beforehand to accommodate and distribute these forces, preventing stress concentration and component failure.

AI summary
A bearing assembly (1) has a slide (9) guided at an angle (13) of a bearing part (6). Angled webs (16, 17) extend from the slide (9) and interact with slot receptacles (21, 22) of a base part (5). During assembly, the bearing part (6) is guided over the base part (5), and the slide (9) is moved. The webs (16, 17) and the slot receptacles (21, 22) create a positive fit between the bearing part (6) and the base part (5). The bearing assembly (1) is particularly compact and highly stable.
