Electronic Component Housing with Precision Positioning Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component housing devices face challenges with tolerances in production, making them unsuitable for use in humid environments and failing to meet DIN standards for assembly in a grid, while also lacking protection against water and electromagnetic interference.
Innovation Solution
A closed housing design using extruded aluminum profiles with integrated positioning elements, such as perforated and threaded strips, ensures precise component placement and torsional rigidity, while seals like silicone or fluorosilicone flat seals provide protection against water and electromagnetic interference, meeting IP65 or IP67 standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If open metal housing is used for subracks, then ease of manufacture and cost-effectiveness are improved, but protection against humidity and water is lost
Solution Approach 1:
The patent applies sealing films or coatings on the metal housing surfaces to provide protection against humidity and water while maintaining the open metal housing structure. This allows the housing to remain manufacturable and cost-effective while gaining environmental protection capabilities.
2Strength
If extruded aluminum profiles are used for bottom and top walls, then torsional rigidity and stability are improved, but manufacturing tolerances in width direction become insufficient for DIN standards
Solution Approach 1:
The patent segments the housing structure into extruded aluminum profiles for bottom and top walls (providing torsional rigidity) and separate positioning elements made from different materials (providing precise width tolerances). This segmentation allows each component to optimize its strengths independently.
Solution Approach 2:
The patent uses composite construction by combining extruded aluminum profiles with positioning elements made from materials having different tolerance characteristics. This composite approach allows the aluminum profiles to provide structural strength while the positioning elements ensure precise dimensional tolerances required by DIN standards.
3Adaptability or versatility
If positioning elements are detachably inserted in profiled sections, then adaptability and ease of assembly are improved, but device complexity increases
Solution Approach 1:
The patent implements universal positioning elements that can be detachably inserted into profiled sections, allowing the same component design to serve multiple functions and configurations. This increases adaptability while the modular nature actually reduces overall complexity by using standardized reusable components.

AI summary
The invention relates to a device (10) for receiving electronic components (24, 26), comprising a housing with bottom, top, front, rear, and side walls (12, 14, 16, 18, 20, 22) and positioning elements (86, 112, 140, 142, 144, 146) by means of which the electronic components can be positioned in the housing. The bottom and top walls (12, 14) are sections of a profile with longitudinal profiling, wherein the positioning elements (86, 112, 140, 142, 144, 146) are detachably inserted into some of the profiling sections. These positioning elements are made of a material different from that of the profile and are manufactured with a tighter tolerance than the profile. Furthermore, guide holders (80) or guide rails for the electronic components (24, 26) can be fixed in the positioning elements.
