Hummingbird Feeder Mounting Member Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hummingbird feeders with flower assemblies often allow unwanted visitors like bees to access nectar, and the design complicates cleaning due to the configuration of the center plugs, making it difficult for hummingbirds to align their beaks and requiring complex disassembly.
Innovation Solution
A hummingbird feeder with a feeding basin and flower assemblies featuring a mounting member with an elongated tapered nectar passageway that prevents bee access while allowing hummingbirds to access nectar, and a semi-conical exterior geometry for easy insertion and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the center part or center plug is made longer and/or narrower to prevent bee access, then bee access is reduced, but hummingbirds may have difficulty aligning their long beaks within the center opening
Solution Approach 1:
The center plug is divided into multiple functional zones: an elongated tapered nectar passageway that narrows toward the nectar source to block bees, and a wider semi-conical outer geometry that provides alignment guidance for hummingbirds. This segmentation allows different regions to serve conflicting functions simultaneously.
Solution Approach 2:
Different portions of the center plug have different geometries optimized for different purposes: the inner passageway is tapered and narrow to prevent bee access, while the outer portion is wider and semi-conical to facilitate hummingbird alignment. This local differentiation resolves the contradiction between bee exclusion and bird access.
2Object-affected harmful factors
If the center plug configuration is made more complex to prevent bee access, then bee access is reduced, but disassembly and reassembly of the feeder for cleaning becomes complicated
Solution Approach 1:
The center plug is designed as a removable component that can be easily extracted from the feed port hole. Despite its complex internal tapered passageway geometry that prevents bee access, the overall component can be simply removed and reinstalled, maintaining low disassembly complexity while achieving high bee exclusion.
3Object-affected harmful factors
If the center plug is made with a narrower opening to prevent bee access, then bee access is reduced, but hummingbirds may have difficulty accessing nectar
Solution Approach 1:
The tapered passageway creates a dynamic interaction where the passageway width varies along its length, being narrow at the nectar end to block bees but widening toward the exterior to accommodate hummingbird beaks. This dynamic geometry change along the passageway allows both bee exclusion and bird access.

AI summary
A hummingbird feeder is provided that includes a nectar container removably coupled to a feeding basin having at least one feed port therein and a flower assembly fitted within the feed port. The flower assembly includes a flower body and a mounting member fitted in the center of the flower body, the mounting member having an elongated tapered passageway through which hummingbirds can access nectar in the feeding basin. The mounting member also has a semi-conical exterior geometry that facilitates mounting of the flower assembly within the feed port.
