Bird Feeder Grain Delivery Inversion and Pneumatic Push
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird feeders with gravity-based grain delivery systems obstruct the field of vision, making observation and photography difficult, and often result in unstable and hindered grain delivery.
Innovation Solution
A grain delivery device for bird feeders that includes a feeding tray with a grain storage cylinder at its bottom, a pushing piece driven by an air-powered driver to push bird food out of the cylinder and onto the tray, and a detection mechanism to monitor bird food stock levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grain storage container is arranged above the feeding tray for gravity-based grain delivery, then the grain delivery function is achieved, but the field of vision is blocked and observation and photography are hindered
Solution Approach 1:
The patent inverts the traditional grain storage container arrangement by placing it at the bottom of the feeding tray instead of above it. This inversion allows birds to access grain from below, eliminating the visual obstruction caused by overhead storage containers while maintaining the grain delivery function.
2Reliability
If gravity-based grain delivery is used, then the structure is simple, but the grain delivery is unstable and hindered
Solution Approach 1:
The patent employs a pneumatic delivery mechanism where compressed air is used to push grain from the storage container through a delivery channel to the feeding tray. This pneumatic system provides stable and controllable grain delivery, overcoming the instability inherent in simple gravity-based systems.
3Quantity of substance
If the grain storage container blocks the field of vision, then the grain storage function is achieved, but observation and photography by bird enthusiasts are hindered
Solution Approach 1:
By inverting the grain storage container to the bottom position and having it protrude upward through the feeding tray, the patent maintains adequate grain storage capacity while eliminating the visual blockage. The inverted arrangement allows clear viewing and photography of birds at the feeding level without obstruction from overhead storage structures.
4Extent of automation
If a pushing mechanism is added to achieve automatic grain delivery, then the grain delivery stability is improved, but the device complexity increases
Solution Approach 1:
The patent uses a pneumatic pushing mechanism where compressed air is introduced into the grain storage container to push grain forward automatically. This pneumatic approach achieves automated grain delivery with relatively simple equipment compared to mechanical pushing systems, reducing overall device complexity while maintaining automation.
