Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional adjustment bushing with drag section is used for tolerance equalization, then the fastening apparatus achieves automatic tolerance equalization, but the assembly and disassembly processes become complex and difficult
Solution Approach 1:
The fastening apparatus is divided into separate functional components: a receiving element with holding projections for secure installation, an adjustment element with drag section for tolerance equalization, and a fastening screw. This segmentation allows each component to perform its specific function while simplifying the overall assembly and disassembly process compared to a single integrated adjustment bushing.
Solution Approach 2:
The adjustment element is extracted as a separate component that can be independently screwed into the receiving element. The drag section is specifically designed to engage with the fastening screw thread, separating the tolerance equalization function from the fastening function. This extraction simplifies assembly by allowing direct screw-in installation and disassembly by reversing the threading action.
2Stability of the object's composition
If the receiving element uses holding projections for positive and frictional connection, then the connection stability is improved, but the device structure becomes more complex
Solution Approach 1:
The receiving element combines multiple functions into a single component: it provides structural support, features holding projections for positive mechanical connection, creates frictional contact surfaces for additional stability, and incorporates a keyhole shape for alignment and insertion guidance. This merging of functions into one element reduces the number of separate parts needed while achieving both stability and avoiding excessive complexity.
Solution Approach 2:
The receiving element serves multiple purposes: it acts as the base mounting component, provides the keyhole interface for alignment, contains the holding projections for secure attachment, and houses the internal thread for receiving the adjustment element. This multi-functionality reduces the overall device complexity by eliminating the need for separate alignment features, mounting structures, and fastening mechanisms.
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
Simplifies the assembly and disassembly process by providing a secure, automatic tolerance equalization mechanism that maintains a stable connection between components A and B, allowing for easy adjustment and removal without requiring a frictional connection, thus enhancing the operational reliability and ease of use.
Implementation Method 1
at least one spring-element, which is arranged adjacent to the flange of the receiving element. This spring element supports on one hand the fastening of the component A between the flange and the holding projection and preferably serves on the other hand to lock the receiving element in the keyhole of component A
Implementation Method 2
the receiving element can be immobilized between the flange and the at least one holding projection on component A through the form—(positive) and/or force-fit (frictional) holding of component A
