Animal Feed Station Safety Program for Data Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automatically supplying feed to animals, such as dairy cattle, can lead to overfeeding due to data connection failures between local and central control units, resulting in incorrect feed dosages being administered.
Innovation Solution
Implementing a safety feed program that reduces feed supply by switching to a safety mode in case of data connection failures, where feed stations either slow down the increase of the feed balance, set a maximum balance, or reduce the feed dose, ensuring that animals receive less feed than intended, thereby preventing overfeeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the feed station operates autonomously using local control unit data, then feed supply speed and responsiveness are improved, but the risk of overfeeding increases due to data connection failures
Solution Approach 1:
The system pre-calculates and stores a safety feed program that limits maximum feed dosage before data connection failures can cause overfeeding. This safety program acts as a pre-prepared cushion against potential data corruption or communication failures, ensuring that even if the central control unit fails, the feed station cannot exceed predetermined safe feeding limits.
Solution Approach 2:
The system continuously monitors data connection status between the local and central control units. When a data connection failure is detected, the system automatically switches from the normal feed program to the safety feed program. This feedback mechanism ensures that the system responds dynamically to connection status changes, maintaining reliability while preserving autonomous operation capability.
2Reliability
If the system switches to safety feed program upon data connection failure, then feed dosage accuracy is improved, but feed supply efficiency decreases due to reduced feed amounts
Solution Approach 1:
The safety feed program implements partial action by providing a reduced but non-zero feed dosage during data connection failures. Instead of completely stopping feed supply, the system delivers a conservative portion of the intended feed amount, balancing the need for accuracy with the requirement to maintain basic animal nutrition and overall system productivity.
Solution Approach 2:
The system dynamically adjusts the feed program based on data connection status. When connected, it uses the full feed program for optimal productivity. When disconnected, it switches to the safety feed program with reduced dosages. This dynamic adaptation allows the system to maintain reliability during failures while minimizing the impact on overall feed supply efficiency.
3Ease of operation
If the feed balance is not reduced upon data connection failure, then system operation simplicity is maintained, but harmful effects occur through animal overfeeding
Solution Approach 1:
The feed station's local control unit autonomously detects data connection failures and automatically switches to the safety feed program without requiring external intervention. The system serves itself by monitoring its own operational status and taking corrective action, maintaining simplicity while preventing overfeeding through automated safety mechanisms.
Solution Approach 2:
The system applies preliminary anti-action by pre-programming safety feed dosages that automatically take effect upon connection failure. This pre-prepared countermeasure prevents the harmful effect of overfeeding before it can occur, as the safety program is already in place and simply needs to be activated when the failure condition is detected.

AI summary
Method of supplying feed to animals with the aid of a group of feed stations which are accessible to those animals, wherein the feed stations, following the identification of an animal, supply feed to that animal according to a feed program for that animal adjusted to that individual animal and taking into account data relating to earlier feed supplies to that animal, wherein data relating to a feed supply to an animal are made available to each feed station via data connections, wherein, in the event of failure of the data connection for at least one of the feed stations, at least one of the feed stations is operated to switch over to a safety feed program to reduce the feed supply to an animal identified at that feed station.
