Housing Construction Kit Coding Means for Electrical Equipment Assembly Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing construction kits for electrical equipment lack technical safety measures during assembly, leading to potential incorrect or dangerous arrangements of plug devices and fuses, which can result in safety hazards due to the lack of certainty in pre-installed device positions and the need for maintaining minimum distances.
Innovation Solution
A housing construction kit with unique coding means on installation openings and plates, including partially transparent plates and frames with pivotable operating flaps, ensures correct assembly by preventing arbitrary placement of installation plates and incorporating a locking mechanism to prevent unintentional closure, thus enhancing technical safety and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If installation plates are made interchangeable for different housing openings, then production flexibility and cost are improved, but assembly safety and device positioning certainty deteriorate
Solution Approach 1:
The patent applies local quality by providing different coding means on different installation plates corresponding to different housing openings. Each installation plate has a specific coding pattern that matches only its designated opening, ensuring that while all plates can be manufactured using the same basic process, their local coding features make them non-interchangeable, thus maintaining assembly safety without sacrificing production efficiency
Solution Approach 2:
The coding means act as an intermediary mechanism between the installation plates and housing openings. These coding features mediate the assembly process by providing a mechanical or geometric interface that allows correct plates to be installed in correct openings while preventing incorrect combinations, thereby ensuring assembly safety without requiring complex assembly procedures
2Reliability
If coding means are added to installation plates and openings, then assembly safety is improved, but device complexity increases
Solution Approach 1:
The patent segments the assembly system into distinct coding elements on installation plates and corresponding coding features on housing openings. This segmentation allows the coding function to be distributed across multiple simple components rather than requiring a single complex locking mechanism, thereby improving assembly safety while minimizing the increase in overall system complexity
Solution Approach 2:
The coding means can be implemented using simple geometric patterns, recesses, or protrusions that are easy to manufacture and inspect. These coding features are essentially copied from standard manufacturing practices rather than requiring new complex mechanisms, allowing assembly safety to be improved with minimal added complexity to the overall device

AI summary
A housing construction kit that includes at least one plug device and/or one fuse. The kit contains a housing base body with numerous installation openings and numerous installation plates. A first coding means is formed on each opening and a second coding means is formed on each plate. Every first coding means of an opening has a unique first coding and every second coding means of a plate has a unique second coding. Every second coding means of a plate is designed to be complementary to at most one first coding means of an opening and every second coding means of a plate is designed to be complementary to a first coding means of another opening as every second coding means of a plate, which is designed to be suitable for assembly of at least one plug device.
