One-Piece Measuring Head Cover for Sealed Serviceable Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of measuring head housings for integrated measuring systems is complex, making it difficult to replace internal components like evaluation electronics and sensors, which are encapsulated and protected by a final sealing, rendering them inaccessible for maintenance or replacement.
Innovation Solution
A method involving a flat cover blank made of anodized aluminum, which is bent into a U-shape using an adhesive to form a one-piece cover that securely seals the measuring head housing, allowing for cost-effective and automated production with recesses for fasteners and electrical contact, simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate covers are used for the measuring head housing, then the housing can be assembled, but the construction becomes complex and requires minimum thickness for interlocking covers
Solution Approach 1:
The patent merges multiple separate covers (side covers and upper cover) into a single one-piece cover structure. This cover blank is formed from a single planar piece of material that is then bent and folded to create the U-shaped cover that surrounds the measuring head housing, eliminating the need for multiple separate cover components and their complex interlocking arrangements.
Solution Approach 2:
The single cover blank is segmented through bending and folding operations to create distinct functional regions (side portions and upper portion) that will form different parts of the housing enclosure, allowing complex three-dimensional geometry to be achieved from a simple planar starting material.
2Volume of moving object
If the upper cover is milled hollow on the inner wall for space reasons, then space is created, but the process becomes complex and expensive
Solution Approach 1:
Instead of performing complex hollow milling operations after the cover is formed, the patent performs preliminary forming operations on the cover blank before final assembly. The cover blank is bent and folded into its final U-shape configuration, creating the necessary internal space and geometry in advance, which eliminates the need for subsequent expensive and complex hollow milling operations.
3Reliability
If evaluation electronics and sensors are encapsulated with casting compound for sealing, then protection against process and environmental influences is achieved, but component replacement becomes almost impossible
Solution Approach 1:
The patent creates a dynamic sealing system where the single-piece cover can be removed and reinstalled, allowing components to be accessed when needed. The adhesive bonding provides sufficient sealing protection during operation but allows for controlled disassembly, transforming the sealing from a permanent static state to a reversible dynamic state that enables maintenance while maintaining reliability during use.
4Ease of manufacture
If covers are glued together by hand, then assembly is possible, but production efficiency is reduced and minimum thickness is required
Solution Approach 1:
The patent combines multiple separate cover pieces into a single monolithic cover blank, eliminating the need for manual gluing operations entirely. The single cover is attached to the housing as one piece, which dramatically increases production efficiency and eliminates the minimum thickness requirements that arise from manual assembly tolerances.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach results in a cost-effective, simplified, and reliably sealed measuring head housing that can be easily assembled and maintained, achieving a fluid-tight seal and facilitating automation, thus addressing the complexity and accessibility issues of previous designs.
Implementation Method 1
an agent for the material connection, preferably an adhesive, for example in the form of a bead of adhesive, is applied to the cover blank
Implementation Method 2
Legs located on the end sections of the cover blank are then bent over in such a way that the means applied to the cover blank comes into contact with the measuring head body
