Rotatable Transmission Base for Drive Shaft Angular Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transmission devices for drive shafts lack versatility and ease of assembly, particularly in applications involving multiple glass panels, as they require complex mounting procedures and limited angular adjustment.
Innovation Solution
A transmission device with a one-piece base body that encloses the drive shaft, featuring a movably mounted pinion and toothed rack, along with a housing that includes a connecting element for mounting to a building structure, allowing for improved attachment options and simplified assembly through rotatable mounting and guide elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the transmission device uses a fixed mounting structure on the building structure, then the structural stability is improved, but the angular adjustment capability deteriorates
Solution Approach 1:
The base body is designed to be rotatably mounted on the housing, allowing the transmission device to dynamically adjust its angular position relative to the building structure while maintaining stable operation. This dynamic mounting enables angular adjustment without compromising structural stability during actual use.
2Manufacturing precision
If the transmission device requires complex mounting procedures, then the mounting precision is improved, but the assembly time deteriorates
Solution Approach 1:
The transmission device is divided into separate modular components: the base body that mounts to the building structure, and the transmission mechanism that attaches to the drive shaft. This segmentation allows each component to be pre-assembled and tested independently, then quickly combined, reducing overall assembly time while maintaining mounting precision through dedicated mounting interfaces.
Solution Approach 2:
The base body is designed with pre-integrated mounting features and the connecting elements are pre-positioned during base body manufacturing. This preliminary preparation of mounting interfaces eliminates the need for complex field assembly operations, allowing rapid installation while ensuring precise mounting alignment.
3Object-affected harmful factors
If the housing is designed as a complex structure, then the protection capability is improved, but the manufacturing cost deteriorates
Solution Approach 1:
The housing serves multiple functions simultaneously: it protects the base body and internal components, provides mounting surfaces for connecting elements, guides the rotational movement of the base body, and serves as a structural support. This multi-functionality eliminates the need for separate protective housings and mounting brackets, reducing overall complexity and manufacturing cost while maintaining comprehensive protection capability.
