Sanitary Insert Orientation Aids for Manual Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual assembly of sanitary inserts, such as jet regulators, is often time-consuming and difficult due to the need for precise orientation of insert screens relative to housing parts, which can be challenging without machine-controlled automation.
Innovation Solution
Incorporating orientation aids on both the housing parts and insert screens, such as centering pins, guide tracks, and toothed structures, to facilitate correct alignment and orientation during assembly, allowing for faster and more accurate assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual assembly is used for sanitary inserts, then flexibility in assembly process is maintained, but assembly time and complexity increase due to difficulty in orienting insert screens correctly
Solution Approach 1:
The patent introduces orientation aids as intermediary elements that mediate between the insert screen and housing part. These aids include protrusions on one component and corresponding recesses or guide structures on the other, which physically guide the components into correct alignment during manual assembly, eliminating the need for complex orientation procedures
Solution Approach 2:
The orientation aids are pre-formed as integral parts of the insert screen and housing part during manufacturing. The protrusions, recesses, and guide structures are created in advance with precise geometry that automatically ensures correct orientation when the components are assembled, eliminating the need for post-manufacturing orientation adjustments
2Manufacturing precision
If manual assembly is used without orientation aids, then device structure remains simple, but manufacturing precision of orientation is difficult to achieve
Solution Approach 1:
The patent employs asymmetric orientation aids where protrusions, recesses, or guide structures have specific non-symmetric geometries that allow only one correct orientation. This asymmetric design ensures that the insert screen can only be assembled in the correct rotational position, achieving high orientation precision through simple geometric constraints rather than complex adjustment mechanisms
Solution Approach 2:
The orientation function is segmented into distinct geometric features: protrusions on one component, corresponding recesses or guide structures on the other component. This segmentation allows each feature to be independently manufactured and optimized, while their combination provides the complete orientation solution without requiring the entire component to be redesigned
