Pump Unit Programming via Housing Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump assemblies require pre-programming of electronic components before final assembly, limiting flexibility and requiring special plug contacts, which complicates manufacturing and reduces accessibility for programming in completed assemblies.
Innovation Solution
A pump assembly design with electrical contacts on a circuit board accessible through an opening in the electronics housing allows for external programming even after assembly, simplifying manufacturing and enabling programming at the end of the production process without external plug contacts, and includes a closure element for sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electronic components are programmed before final assembly using contacts inside the electronics housing, then programming can be performed, but the housing must remain open and accessibility is limited
Solution Approach 1:
The housing is segmented into a first housing part and a second housing part, with the first part containing the opening for contact access and the second part providing protection. This segmentation allows the opening to be present during assembly while enabling sealed protection afterward.
Solution Approach 2:
The opening is pre-formed in the housing structure to enable programming access during assembly. The closure element is then applied afterward to seal the opening, ensuring programming can occur before final sealing without compromising housing integrity.
2Ease of operation
If plug contacts are provided outside the housing for programming, then programming is accessible, but the device structure becomes more complex
Solution Approach 1:
The contact access function is extracted from the interior of the housing and made accessible through an opening in the housing wall. This eliminates the need for external plug contacts while maintaining programming accessibility through the housing structure itself.
Solution Approach 2:
The housing structure serves multiple functions: it provides mechanical protection, contains the electronics, and incorporates an opening that enables programming access. This multi-functionality eliminates the need for separate external plug contact structures.
3Reliability
If the electronics housing is sealed to protect internal components, then protection is improved, but programming contacts become inaccessible
Solution Approach 1:
The opening is incorporated into the housing structure before sealing, allowing programming to occur during assembly. The closure element is then applied to seal the housing, ensuring both accessibility during assembly and protection in the final state.
Solution Approach 2:
The housing is divided into segments with the first part providing the opening for access and the closure element providing the seal. This segmentation allows the housing to be open during programming and sealed for protection afterward.
4Adaptability or versatility
If programming is performed before final assembly, then electronic components can be configured, but manufacturing steps must be extended
Solution Approach 1:
The opening in the housing enables programming to occur during the final assembly stage rather than requiring a separate pre-assembly programming step. This integration of programming into the assembly process itself streamlines manufacturing.
