Adjustable Actuator for Flush Wall-Mounted Control Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ablutionary settings, the variability in wall cavity depths and space requirements leads to inconsistent projection of control members from the wall, necessitating trimming of back and front plates, which is not ideal for design consistency.
Innovation Solution
An adjustable length actuator system is used, allowing the distance between its surfaces to be lengthened or shortened, enabling the control member to sit flush with the faceplate regardless of wall depth, thereby maintaining consistent projection and reducing the need for precise trimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trimming of back plate and front plate is performed to accommodate varying wall cavity depths, then the control member can be made to sit flush with the faceplate, but the projection distance of the front plate from the wall becomes inconsistent
Solution Approach 1:
The actuator is designed with an adjustable length mechanism that allows it to be extended or retracted to different positions. This dynamic adjustment capability enables the actuator to compensate for variations in wall cavity depth, allowing the front plate to maintain a consistent projection distance from the wall while still achieving a flush finish between the control member and faceplate across different installation scenarios.
2Ease of manufacture
If fixed length actuators are used, then the assembly process is simpler, but the system cannot accommodate different wall cavity depths
Solution Approach 1:
The actuator incorporates an adjustable length mechanism that allows it to be configured for different wall cavity depths during installation. This dynamic feature provides adaptability to various installation conditions while maintaining a relatively simple overall assembly process, as the adjustment can be made in-situ without requiring complex preconfiguration or multiple specialized components.
Solution Approach 2:
The actuator's length parameter can be changed to accommodate different wall cavity depths. By allowing the actuator length to be adjusted within a range, the system gains versatility to adapt to various installation scenarios while keeping the base design simple and the assembly process straightforward.
3Adaptability or versatility
If trimming is required for different wall depths, then installation can be adapted to various cavities, but the accuracy required for trimming increases
Solution Approach 1:
The adjustable actuator eliminates or reduces the need for precise trimming by providing a mechanical means to accommodate wall depth variations. The actuator can be extended or retracted to compensate for different cavity depths, thereby maintaining adaptability to various installations while significantly reducing the trimming accuracy requirements compared to fixed-length systems.
