Deformable Compensation Element for Actuator Assembly Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuation apparatuses face difficulties in assembly due to the need for precise orientation of the pressure actuation element relative to the housing or facing, often requiring millimeter-precise alignment, which complicates the installation process and allows for limited tolerances.
Innovation Solution
Incorporating a deformable compensation element between the pressure actuation element and the application location, allowing for radial position changes and enabling correct orientation, thus allowing for simpler assembly with greater tolerances and eliminating the need for play between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pressure actuation element is inserted in an opening of the facing or housing in the assembled state, then the actuation apparatus can be connected to the functional device, but millimetre-precise orientation of the actuation apparatus and the facing or housing relative to each other is necessary, which complicates the assembly process
Solution Approach 1:
The patent applies parameter changes by introducing a deformable compensation element that can radially adjust its dimensions to accommodate position changes of the pressure actuation element. This deformability allows the system to maintain precise radial positioning (improving orientation precision) while accommodating assembly tolerances and simplifying the assembly process (reducing assembly complexity).
Solution Approach 2:
The compensation element serves as an intermediary between the pressure actuation element and the control element. It absorbs and compensates for radial position deviations, enabling the pressure actuation element to be correctly oriented relative to the housing opening without requiring millimetre-precise alignment during assembly. This mediator approach resolves the contradiction by decoupling the precision requirement from the assembly process.
2Manufacturing precision
If the pressure actuation element is inserted in an opening of the facing or housing in the assembled state, then the actuation apparatus can be connected to the functional device, but millimetre-precise orientation of the actuation apparatus and the facing or housing relative to each other is necessary, which increases the time required for assembly
Solution Approach 1:
The deformable compensation element changes its radial parameters to accommodate position variations of the pressure actuation element. This allows correct orientation to be achieved without millimetre-precise alignment, significantly reducing the time required for assembly while maintaining the necessary orientation precision for proper functionality.
Solution Approach 2:
The compensation element acts as a mediator that eliminates the need for time-consuming precise alignment procedures. By absorbing radial position deviations, it enables rapid assembly while ensuring the pressure actuation element achieves correct orientation relative to the housing opening, thus resolving the time-precision trade-off.
3Ease of manufacture
If play is configured between the control element and the pressure actuation element and/or between the control element and the compensation element, then assembly is simplified, but the connection becomes less stable and secure
Solution Approach 1:
The compensation element utilizes parameter changes (radial deformation) to accommodate position variations without creating play. The deformable structure maintains continuous contact and stable connection while allowing the pressure actuation element to be correctly oriented, thus achieving both assembly simplicity and connection stability simultaneously.
Solution Approach 2:
The compensation element introduces dynamics by being deformable rather than rigid. It can dynamically adjust its radial dimensions to maintain optimal contact with the control element and pressure actuation element, ensuring stable connection without play while still allowing for simplified assembly through its ability to accommodate position variations.

Implementation Method 1
at least one deformable compensation element is arranged or constructed between the pressure actuation element and the application location, wherein a position change of the pressure actuation element relative to the application location in a radial direction is possible as a result of the compensation element
