Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sensor housings with base plates and multiple fastening bores are used, then the sensor can be securely attached, but the alignment requires considerable adjustment and assembly effort which is time-consuming and expensive
Solution Approach 1:
The feet are pre-formed as integral parts of the housing body during manufacturing, with mounting bores and support projections already positioned. This preliminary preparation eliminates the need for separate alignment and adjustment operations during assembly, allowing the sensor housing to be directly mounted in the correct position.
Solution Approach 2:
The feet are merged with the housing body as a single integral component rather than separate parts. This combination simplifies the assembly process by reducing the number of components and elimination of alignment operations between separate base plate and housing parts, while maintaining secure attachment capability.
2Manufacturing precision
If conventional sensor housings with base plates are used, then the sensor can be mounted at predetermined positions, but the assembly process is complex and expensive
Solution Approach 1:
The mounting bores and support projections are pre-positioned on the feet during housing manufacturing. This preliminary action ensures precise alignment is built into the component itself, eliminating the need for complex adjustment procedures during assembly while maintaining high manufacturing precision.
Solution Approach 2:
The three support projections on the feet automatically provide self-alignment of the sensor housing during mounting. The feet themselves serve the dual function of attachment and alignment, eliminating the need for separate alignment mechanisms or complex assembly procedures.
3Stability of the object's composition
If the sensor system is rigidly connected to the housing body, then structural stability is achieved, but stresses during attachment can misalign the sensor
Solution Approach 1:
The feet are designed with elastic properties, changing the mechanical parameter of rigidity to flexibility. This allows the attachment structure to accommodate stresses during mounting through elastic deformation, preventing stress transmission to the sensor system while maintaining overall structural stability.
Solution Approach 2:
The elastic feet serve as an intermediary element between the rigid housing body and the mounting structure. They absorb and accommodate attachment stresses, acting as a buffer that protects the sensor alignment while still providing secure mechanical attachment.

Function Achieved in This Case
Enables precise and secure alignment and attachment of the sensor, reducing assembly time and costs while preventing air pockets and enhancing the reliability of signal connections.
Implementation Method 1
the feet are also particularly advantageously designed to be elastic, so that the attachment zones on the attachment bores of the feet are connected elastically to the housing body, which contains the sensor system

AI summary
The housing (2) has a housing body (21) opened downwards, so that a housing interior is exposed downwards. Feet (20) are formed as a single piece with the housing body, and a fastening borehole is provided at the feet for fastening the housing at a preset position. Three supporting projections (202) are provided at a lower side of the housing body and/or the feet for aligning the housing at a preset supporting position. Circular metallic inserts are provided in the fastening boreholes for reinforcing and securing an attachment.
