Tilting Joint Threaded Sleeve Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilting joint arrangements for articulated arm awnings lack operational reliability and freedom from faults due to the lack of a stop to limit screw-in depth and exposure of the threaded spindle, leading to potential damage from environmental influences and aesthetics issues.
Innovation Solution
Designing the threaded sleeve as a closed sleeve with a connection element on its closed end to prevent the threaded spindle from emerging and providing a predetermined pivoting angle stop, along with a locking pin for roll-up safety, ensures the threaded spindle remains protected and the awning is securely positioned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a continuous threaded bore is used in the threaded sleeve, then the threaded spindle can be screwed in deeply for adjustment, but the threaded spindle emerges from the sleeve and becomes exposed to environmental damage and aesthetic issues
Solution Approach 1:
The threaded sleeve is segmented into two distinct parts: a closed end portion that protects the threaded spindle and an open end portion that allows adjustment. This segmentation enables the sleeve to simultaneously provide protection and adjustment functionality, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
Different portions of the threaded sleeve have different structural qualities - the closed end provides protection and aesthetic coverage while the open end allows for threading and adjustment. This local differentiation of quality enables the single component to satisfy both protective and operational requirements.
2Ease of operation
If the threaded sleeve is designed as an open bushing, then the connection element is easily accessible, but the threaded spindle is exposed and can be damaged by environmental influences
Solution Approach 1:
The threaded sleeve is divided into protected and accessible zones, where the closed end shields the threaded spindle from environmental harm while the open end maintains accessibility for connection element attachment. This spatial segmentation resolves the contradiction between protection and accessibility.
3Adaptability or versatility
If the threaded spindle is allowed to emerge for adjustment, then the pivoting movement can be achieved, but the thread becomes soiled and damaged leading to malfunctions
Solution Approach 1:
The threaded sleeve structure segments the adjustment mechanism into a protected zone (closed end) and an operational zone (open end), allowing the threaded spindle to remain protected while still enabling pivoting movement through the accessible connection element at the open end.
Solution Approach 2:
The closed end of the threaded sleeve acts as an intermediary protective barrier between the threaded spindle and the external environment, preventing direct exposure to soiling and damage while still allowing the mechanical function to operate through the open end connection.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances operational reliability by preventing the threaded spindle from being exposed, protecting it from damage, and ensuring the awning remains securely adjusted, maintaining aesthetics and preventing uncontrolled movement during wind or retraction.
Implementation Method 1
The closed threaded sleeve advantageously results in a stop against which the threaded spindle can start to limit the screw-in depth and thus the pivoting movement of the support part
Implementation Method 2
the adjusting spindle arrangement is constructed in several parts and has a threaded spindle fixedly attached to the bearing block in the axial direction and direction of rotation and a rotatable threaded sleeve carrying the head, with which the Threaded spindle is in threaded engagement
Implementation Method 3
the head of the threaded sleeve has an undercut rear side facing away from the support surface of the supporting part, with which a locking pin arranged in the supporting part can be engaged and disengaged

AI summary
In a tilting joint for a folding arm awning, the assembly comprises a bearing block (12) that can be fixed to a stationary mounting surface and a support element (7) for an awning arm bearing (4) that is pivotably mounted thereon about a tilting axis (11) parallel to the plane of the folding arm and is adjustableally supported thereon by an adjusting spindle assembly (13). The adjusting spindle assembly (13), which engages the bearing block (12) on one side, is supported on the other side by a radially projecting head (19) on a support surface (24) of the support element (7) facing away from the bearing block (12). The adjusting spindle assembly (13) is multi-part and comprises a drive spindle (18) fixed to the bearing block (12) in the axial direction and direction of rotation, and a rotatable threaded sleeve (20) supporting the head (19), with which the threaded spindle (18) engages. The threaded sleeve is not visible on the threaded sleeve. (20) emerges.
