Frame Element Assembly With Insert-Mounted Bearing Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame element arrangements for building locking devices face challenges in simple and reliable mounting of the operating element with a conventional bearing block, often requiring expensive and difficult-to-install spacer sleeves that can damage the gear mechanism.
Innovation Solution
The bearing block is fastened to the frame element using an insert part fully inserted into the frame element, bypassing the gear mechanism, allowing for secure attachment without direct support from the gear housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bearing block is fastened directly to the gear housing, then the mounting is simple, but the gear mechanism may tilt or become damaged
Solution Approach 1:
The patent introduces an insert part as an intermediary component between the bearing block and the frame element. This insert part is fully inserted into the frame element and provides a mounting surface for the bearing block, thereby preventing direct fastening to the gear housing and avoiding gear tilting while maintaining mounting simplicity
Solution Approach 2:
The mounting structure is segmented into three distinct components: the frame element, the insert part, and the bearing block. This segmentation allows the insert part to be independently positioned within the frame element, providing structural support without involving the gear mechanism, thus resolving the contradiction between ease of mounting and gear stability
2Reliability
If spacer sleeves are used to support the bearing block, then the gear mechanism is protected from tilting, but the device complexity and installation difficulty increase
Solution Approach 1:
The insert part is designed as a simple, inexpensive component that can be easily manufactured and installed. It serves as a temporary structural solution during operation, providing necessary support without the complexity of adjustable spacer sleeves, while maintaining gear stability
3Reliability
If the bearing block is fastened bypassing the gear mechanism, then the gear tilting is prevented, but the fastening structure becomes more complex
Solution Approach 1:
The insert part combines multiple functions into a single component: it provides structural support for the bearing block, serves as a mounting base, and integrates with the frame element's internal cavity. This merging simplifies the overall fastening structure compared to using separate spacer and fastening components
