Measuring Housing Wall Mounting Without Front Access Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure measuring devices in automation technology face challenges in wall mounting without horizontal holes, especially when the device's front is compact and filled with a display, or for aesthetic reasons where visible holes are undesirable.
Innovation Solution
The method involves drilling holes in the wall according to the housing's back pattern, using hexagon socket screws with a ball head wrench through oblique holes in the device's sides or top/bottom, and securing the housing with keyhole-like recesses to achieve stable attachment without affecting the front display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wall mounting is performed using horizontal holes through the front of the housing, then the measuring device can be securely attached to the wall, but the front display area is compromised and visible holes are created which are aesthetically undesirable
Solution Approach 1:
The patent transitions from horizontal hole placement on the front surface to oblique hole placement on the side surface, changing the spatial dimension and orientation of the mounting interface. This allows screws to enter through the side at an angle, securing the device to the wall without compromising the front display surface.
Solution Approach 2:
The housing is segmented into functional zones: the front surface remains intact for display purposes, while the side surface contains oblique holes for mounting. The keyhole recesses are positioned on the rear surface, separating the aesthetic front from the functional mounting areas.
2Shape
If the housing is designed with a compact front filled entirely with display, then aesthetic appearance is improved, but wall mounting without horizontal holes becomes impossible using conventional methods
Solution Approach 1:
Instead of attempting to mount through the front surface, the patent utilizes the side surface with oblique holes and the rear surface with keyhole recesses. This three-dimensional redistribution of mounting features enables wall attachment while preserving the compact front design.
Solution Approach 2:
The keyhole recesses act as an intermediary mechanism between the screws and the housing. The rounded portion of the keyhole allows the screw head to be inserted and positioned, while the narrow portion provides lateral constraint, enabling secure mounting without front surface intervention.
3Reliability
If screws are inserted through oblique holes and tightened using a ball-end hex key, then secure fixation is achieved, but the tightening process requires precise alignment and access through angled holes
Solution Approach 1:
The ball-end hex key serves as an intermediary tool that can be inserted through the oblique hole to engage the hex socket of the screw head. The ball end allows for precise alignment and engagement, enabling tightening operations through the angled access hole.
Solution Approach 2:
The keyhole recess is designed with a rounded portion that allows the screw head to be preliminarily positioned and aligned before tightening. This preliminary positioning action facilitates easier engagement of the hex key and subsequent tightening operation.

AI summary
The invention relates to a method for fastening a housing for a measuring device of process or automation technology to a wall, which method is characterized by the following method steps: - drilling at least two holes (6) in the wall (2) corresponding to the pattern of holes on the housing rear side (11); - screwing one hexagon socket screw (4) into each of these holes (6), with a spacing between wall and screw head corresponding at least to the thickness of the housing rear side (11); - placing the measuring device housing (10) onto the wall (2) such that the screw heads of the screws (4) located in the wall are each guided through the wide regions of at least two keyhole-like cutouts (12) in the housing rear side (11); - pushing the measuring device housing (11) downwards such that the screw stems of the at least two screws (4) are in each case located in the narrow region of the at least two keyhole-like cutouts (12); - introducing a hexagon key (5) with a spherical head into at least two obliquely running bores (13) such that the ball head engages in the hexagon socket of the screw head and the respective screw (4) is tightened.
