Adapter Positioning Tabs for Irregular Wall Recess Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for aligning and fastening installation housings in wall recesses are complex and inefficient, particularly in irregularly shaped wall recesses, and often require costly and labor-intensive processes.
Innovation Solution
An adapter with a carrier element, positioning tabs, and a sliding guide is used to align and secure the installation housing within the wall recess, allowing for precise positioning and easy assembly, while the positioning tabs provide a resilient contact with the wall to prevent tilting and facilitate secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fixing aids with rib-like projections are used to align installation housings in wall recesses, then positioning is achieved, but the alignment precision deteriorates when wall recesses have irregular shapes deviating from circular cross-sections
Solution Approach 1:
The adapter features positioning tabs with contact edges that have locally adapted geometries. Each contact edge is designed to match specific wall recess shapes (circular, rectangular, or irregular), allowing precise alignment while accommodating variations in wall recess geometry. This local adaptation resolves the contradiction by providing shape-specific contact surfaces rather than uniform rib-like projections.
Solution Approach 2:
The positioning tabs can be manufactured with different geometries, materials, or flexibility parameters to suit different wall recess shapes. The contact edges may have varying degrees of elasticity or structural compliance, allowing them to conform to irregular surfaces while maintaining precise positioning. This parameter variability enables both precision and adaptability simultaneously.
2Measurement precision
If complex fixing mechanisms are used to ensure precise alignment in irregular wall recesses, then alignment precision improves, but device complexity increases
Solution Approach 1:
The adapter serves as an intermediary component between the installation housing and the wall recess. Rather than modifying the housing or directly engaging with irregular wall surfaces, the adapter's positioning tabs mediate the connection, providing a simplified interface that achieves precise alignment without complex mechanisms. This intermediary approach resolves the contradiction by isolating the complexity to a single adaptable component.
Solution Approach 2:
The positioning tabs can be designed as simple, inexpensive components that are easy to manufacture and replace. Rather than using complex, expensive alignment mechanisms, the patent employs straightforward positioning tabs that can be produced cost-effectively and are simple to install and remove if needed. This simplicity resolves the contradiction between precision and complexity.
3Reliability
If installation housings are secured using multiple screws and filler materials in irregular wall recesses, then fastening reliability improves, but the installation process becomes more time-consuming
Solution Approach 1:
The positioning tabs are pre-configured on the adapter before installation. Their geometries are predetermined to match specific wall recess shapes, eliminating the need for on-site adjustments, filler applications, or complex alignment procedures. This preliminary preparation resolves the contradiction by ensuring reliable fastening through pre-engineered contact surfaces that require no additional installation steps.
Solution Approach 2:
The positioning tabs are designed to self-align and self-position the installation housing within the wall recess. The contact edges automatically engage with the wall surface in the correct orientation and position, eliminating the need for manual alignment, filler application, or multiple screw adjustments. This self-service capability resolves the contradiction by achieving reliable fastening through automatic positioning rather than labor-intensive procedures.

AI summary
The invention relates to an adapter for positioning and securing an installation housing in a wall recess, wherein a support element has a contact surface for direct or indirect contact with the installation housing, wherein the support element has at least one connection element for fastening to the installation housing, wherein positioning tabs are arranged opposite the contact surface on the support element, spaced apart from each other in the depth direction and transversely to the depth direction, and wherein the positioning tabs are oriented away from the support element and form contact edges facing away from the support element. The adapter enables the quick and secure fastening of the installation housing in a wall recess.
