Solution Overview

Problem

Individual egg-laying nests face challenges in controlling the presence of multiple animals without reducing nest frequentation, as existing designs lack stable open positions and effective opening control mechanisms, often resulting in unstable intermediate positions that allow simultaneous entry and exit.

Innovation Solution

The implementation of opening and closing control means with positive action, combined with a presence sensor and thrust detection sensor, allows for quick closure upon animal entry and assisted opening upon exit, using a double-acting cylinder actuator and three-position distributor to manage the closing mechanism, ensuring a stable open position and easy operation by the animal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If closing means are designed with only closing control means, then the nest remains in a stable closed position, but the nest lacks a stable open position and cannot maintain controlled opening state

Engineering Contradiction:
Improvestable closed positionVSAvoidstable open position
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The closing means are designed with dynamic control capabilities through opening control means and closing control means that can actively transition between stable closed position and stable open position, rather than relying on passive mechanical equilibrium. The control means enable the system to maintain either state stably based on operational needs.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If closing means are always in closed position without opening control, then animal entry is controlled, but animal exit is difficult and nest frequentation rate decreases

Engineering Contradiction:
Improvemultiple animals in nestVSAvoidnest frequentation rate
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

Presence detection means detect when an animal is inside the nest and provide feedback to the control means, which then automatically activate opening control means to assist the animal in opening the closing means for exit. This feedback mechanism ensures timely opening without requiring manual intervention, maintaining high nest frequentation.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If opening control means are added to enable stable open position, then ease of operation improves, but device complexity increases

Engineering Contradiction:
Improvestable open positionVSAvoidcontrol means structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control means are designed to perform multiple functions: closing control means activate the closing means, opening control means activate the opening means, and presence detection means monitor animal presence. This multi-functional integration reduces the need for separate dedicated components for each function, managing device complexity while achieving stable open position control.

Inventive Principle:
Principle #6Universality (Multi-functionality)
