Deformable Plate Fastening for Play-Free Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for components on devices, such as magnetic control valves and transmission actuators, often result in complex designs and require additional clamping elements, leading to play and mechanical overstressing during assembly.
Innovation Solution
A fastening arrangement featuring a locally deformable plate with weakened regions and deformation zones, where spacers extend from the device to the component's surface, allowing the unweakened receiving area to be braced with screws, deforming the plate for a force-fitting and form-fitting connection without additional elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fastening arrangements are used, then components can be secured to devices, but the design becomes complex and requires additional clamping elements
Solution Approach 1:
The patent combines the fastening element and clamping function into a single integrated plate structure. The plate includes both a receiving area for mounting and deformation zones for clamping, eliminating the need for separate clamping elements and reducing overall assembly complexity while maintaining secure connection.
Solution Approach 2:
The plate is segmented into functionally distinct zones: an unweakened receiving area for structural support and mounting, and weakened deformation zones for elastic clamping action. This segmentation allows each zone to perform its specific function optimally without interfering with other parts of the fastening arrangement.
2Reliability
If additional clamping elements are used, then secure fastening is achieved, but the number of parts increases and assembly becomes more difficult
Solution Approach 1:
The clamping function is merged directly into the plate structure through deformation zones that can elastically deform to engage with the component. This integration eliminates the need for separate clamping elements and reduces the number of assembly steps, making the process simpler while maintaining secure fastening.
3Reliability
If conventional fastening methods are used, then components are secured, but play and mechanical overstressing occur during assembly
Solution Approach 1:
The plate's local thickness parameter is changed through weakened zones that reduce material thickness in specific areas. This allows the plate to deform elastically under clamping load, enabling precise adjustment to achieve play-free form-fitting connections without overstressing the component or requiring high-precision manufacturing tolerances.
Solution Approach 2:
The plate exhibits local quality variations with different thicknesses and material properties in different zones. The deformation zones have reduced thickness for elastic compliance, while the receiving area maintains full thickness for structural strength. This local differentiation enables precise, play-free connections while protecting the component from mechanical overstressing.
