Baler Door Safety Latch for Fail-Safe Closure Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balers pose a safety risk as the upper door can accidentally close, potentially catching a user's hand, especially when the door movement mechanism fails.
Innovation Solution
A safety system is integrated into the baler, featuring a safety arm connected to the door movement means, latching means that can move between allowing and preventing door movement, and equilibrium means that shifts the latching means to prevent door closure when the door movement means is interrupted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock is provided to prevent accidental door closure, then safety is improved, but the device becomes more complex and the lock is cumbersome to operate
Solution Approach 1:
The patent extracts the safety function from a traditional lock mechanism and implements it through a separate safety arm with latching means that engages with receiving means on the door. This separates the safety function from the door movement mechanism, providing safety without requiring a cumbersome lock that needs to be manually operated.
Solution Approach 2:
The safety system operates automatically through the interaction between the safety arm, latching means, and equilibrium means. When the door movement means is interrupted, the equilibrium means automatically moves the latching means to engage with the receiving means, preventing accidental closure without requiring user intervention or a manual lock.
2Reliability
If a lock is provided to prevent accidental door closure, then safety is improved, but ease of operation deteriorates due to cumbersome lock operation
Solution Approach 1:
The safety system operates automatically through the interaction between the safety arm, latching means, and equilibrium means. When the door movement means is interrupted, the equilibrium means automatically moves the latching means to engage with the receiving means, preventing accidental closure without requiring user intervention or a manual lock.
Solution Approach 2:
The safety arm is pre-configured with latching means that can engage with receiving means on the door. The equilibrium means is pre-positioned to automatically activate the latching mechanism when the door movement means fails, preventing closure before an accident can occur without requiring manual lock operation.
3Ease of operation
If the door can be opened most of the time for waste deposition, then ease of operation is improved, but safety deteriorates due to risk of hand catching when door closes
Solution Approach 1:
The safety system uses simple, robust mechanical components (safety arm, latching means, equilibrium means) that provide reliable safety protection. These components are designed to be fail-safe and automatically activate when needed, providing continuous safety protection without interfering with normal door operation during waste deposition.
Solution Approach 2:
The safety function is extracted from the door movement mechanism itself and implemented through a separate safety arm system. This allows the door to remain freely operable for waste deposition while an independent safety mechanism provides protection against accidental closure, separating the operational freedom from safety concerns.
4Reliability
If a safety system with latching means is implemented, then safety is improved by preventing door closure when movement means is interrupted, but device complexity increases
Solution Approach 1:
The safety arm is connected to both the door movement means and the latching means, merging these functions into a single integrated component. The equilibrium means serves dual purposes by both positioning the latching means and providing the force for automatic engagement, reducing the need for additional separate mechanisms.
Solution Approach 2:
The safety arm acts as an intermediary component that connects the door movement means to the latching means. This intermediate element translates the state of the door movement means into the appropriate latching action, providing a simple mechanical linkage that avoids the need for complex control systems or multiple separate components.

Function Achieved in This Case
The safety system effectively prevents the door from closing when the door movement mechanism fails, thereby reducing the risk of accidents and eliminating the need for cumbersome locks.
Implementation Method 1
equilibrium means connected to the safety arm and configured for moving the latching means from the first position to the second position when the door movement means is interrupted

AI summary
Disclosed is a baler (100, 200) for making bales of a waste material. The baler comprises a compaction compartment (102, 202), a door (104, 204), door movement means (106, 206), and a frame part (108, 208). The frame part comprises at least one receiving means (110, 210). The baler comprises a safety system (112, 212). The safety system comprises a safety arm (114, 214) configured to be connected to the door movement means, latching means (116, 216) connected to the safety arm and configured for moving between a first position (118, 218) allowing the door to move and a second position (120, 220) preventing the door from moving by engaging into the at least one receiving means, and equilibrium means (122, 222) connected to the safety arm and configured for moving the latching means from the first position to the second position when the door movement means is interrupted.
