Compact Bulkhead Housing with Internal Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulkhead mounted housings are time-consuming to assemble and require significant space due to externally formed fastening openings, which complicates leak-tight sealing and stability, especially in environments with vibration loads.
Innovation Solution
A compact bulkhead mounted housing with internally located fastening devices and clamping elements that secure the housing to a wall aperture without external sealing rings, utilizing hinged clamping elements with spring action for tool-free assembly and a space-saving design, allowing for flexible use with various plug connector modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If externally formed fastening openings are used, then the housing can be securely fastened to the wall aperture, but the housing requires significant space on the device wall
Solution Approach 1:
The fastening openings are integrated within the frame-like base form structure itself, nesting the fastening function inside the housing rather than adding external protrusions. This allows the fastening mechanism to be contained within the existing footprint of the housing, securing fastening capability while minimizing wall space requirements
2Reliability
If multiple sealing rings are provided for leak-tightness, then the housing is protected from environmental influences, but the assembly becomes very time consuming
Solution Approach 1:
The sealing function is merged with the fastening openings by integrating sealing rings directly into the fastening opening structure. This combination means that the same component serves dual purposes: providing mechanical fastening and ensuring leak-tightness simultaneously, thereby maintaining reliability while significantly reducing assembly time
Solution Approach 2:
The sealing rings are positioned such that they are automatically engaged and secured during the fastening process itself, without requiring separate assembly steps. The fastening action itself serves to install and activate the sealing function, eliminating the need for additional manual sealing operations
3Stability of the object's composition
If externally formed fastening openings are used, then the housing can be securely fastened, but the assembly requires significant space on the device wall
Solution Approach 1:
The fastening openings are nested within the frame-like base form structure, allowing the fastening mechanism to be contained within the housing's existing boundary. This integration maintains fastening stability while minimizing the external footprint and space requirements on the device wall
