Selective Bird Feeder Using Sensor-Based Species Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bird feeding devices lack the ability to selectively provide bird feed to desired species while restricting access to undesired species, leading to inefficiencies and waste, as well as the exclusion of preferred bird species.
Innovation Solution
An electronic bird feeding device equipped with a sensor system that uses color, light reflectance, body weight, and image recognition to determine the species of birds approaching the feeder, actuating a door mechanism to open or close access to the feed based on predefined criteria, ensuring that only desired bird species receive the feed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional bird feeding devices are used, then all birds can access the feed freely, but this leads to waste and excludes preferred species
Solution Approach 1:
The patent applies local quality by providing different access conditions to different bird species. The sensor system identifies specific species and triggers selective door operation, allowing preferred species (e.g., cardinals) free access while restricting undesired species (e.g., blackbirds). This localized differentiation resolves the contradiction by optimizing feed access for specific species rather than uniform access for all birds.
Solution Approach 2:
The patent implements feedback through the sensor system that continuously monitors approaching birds and provides real-time information to the control mechanism. The sensor detects species characteristics, feeds this information to the controller, which then adjusts door operation accordingly. This closed-loop feedback system enables dynamic adjustment of feed access based on actual bird presence, reducing waste while maintaining efficiency for preferred species.
2Loss of substance
If selective species detection is implemented, then feed waste is reduced, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical species identification systems with sensor-based detection. Instead of using intricate mechanical mechanisms to distinguish bird species, the system employs optical or electromagnetic sensors that detect species characteristics non-contactly. This substitution reduces mechanical complexity while achieving the same waste reduction goal through electronic detection and control.
Solution Approach 2:
The sensor system automatically identifies bird species and triggers appropriate door operation without human intervention. The system serves itself by detecting species characteristics, making decisions, and executing door control autonomously. This self-service capability reduces the need for complex manual control mechanisms while achieving effective species-based feed restriction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively restricts access to undesired bird species while allowing preferred species to feed, reducing waste and enhancing the attractiveness of the feeder for desired bird species, thereby optimizing bird feeding efficiency and user preferences.
Implementation Method 1
The sensor is configured to radiate energy to a position outside of the housing and adjacent to the opening. The sensor receives reflected radiation reflected off of an object adjacent to the opening.

AI summary
A selective bird feeding apparatus includes a housing having an access opening and door mounted positionable in a closed condition or in an open condition relative to the access opening. A drive mechanism is actuated to move the door to the closed condition or to the open condition. An actuator coupled to the drive mechanism includes a sensor which radiates energy to a position adjacent to the opening. The sensor receives reflected radiation reflected off of an object adjacent to the opening. A control circuit assigns an input value to the reflected radiation which is compared with a stored standard value. The actuator actuates the drive mechanism to move the door to the closed condition when the input value is outside a threshold limit of the standard value and actuates the drive mechanism to move the door to the open condition when the input value is within the threshold limit.
