Problem
Conventional unload tees are difficult to operate at certain angles or in specific situations, leading to haphazard securing and potential damage during material delivery, necessitating a secure, safe, and easy-to-operate solution.
Innovation Solution
An unload tee design featuring a tee body with a rotatable door, a latch assembly with a catch pin and snaking bar, and a U-Bolt for secure engagement and disengagement, allowing for easy operation and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional unload tees are used, then the structure is simple, but the ease of operation deteriorates at certain angles or situations
Solution Approach 1:
The latch assembly is designed with a snaking bar that can dynamically adjust its position along the door, allowing the operator to engage and disengage the latch from various angles. The snaking bar's flexible geometry enables it to reach the U-Bolt connection at multiple orientations, directly resolving the operational difficulty at certain angles while maintaining reasonable structural complexity
Solution Approach 2:
The latch assembly is segmented into distinct functional components: the snaking bar for engagement, the U-Bolt for securement, and the catch mechanism for locking. This segmentation allows each component to be optimized for its specific function, improving overall operability without requiring a completely complex integrated structure
2Reliability
If conventional unload tees are used, then the device complexity is low, but the reliability deteriorates due to haphazard securing
Solution Approach 1:
The latch assembly provides beforehand securement by engaging the snaking bar with the U-Bolt connection before material delivery begins. This pre-securing mechanism prevents haphazard positioning during operation, ensuring the door remains firmly closed throughout the delivery process, thereby improving reliability without adding excessive complexity
Solution Approach 2:
The catch mechanism automatically engages with the catch pin when the door is closed, providing self-latching functionality. This self-service feature ensures reliable securing without requiring additional manual intervention or complex external locking mechanisms, achieving high reliability with moderate device complexity
3Reliability
If a secure latch mechanism is implemented, then the reliability improves, but the ease of operation may deteriorate due to additional components
Solution Approach 1:
The latch assembly merges multiple functions into a single integrated mechanism: the snaking bar serves as both the engagement tool and the securing element, while the U-Bolt provides both structural support and the locking interface. This merging allows the operator to secure the door with a single action rather than multiple separate steps, maintaining ease of operation while achieving high reliability
Solution Approach 2:
The snaking bar acts as an intermediary element between the operator's action and the U-Bolt connection. By providing this intermediate engagement point, the mechanism simplifies the operation of securing a heavy door, as the snaking bar can be easily manipulated to engage and disengage the robust U-Bolt connection, balancing reliability with operational ease

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures secure and safe operation by allowing for easy opening and closing of the unload tee, preventing damage during material delivery and enhancing operational ease.
Implementation Method 1
The door is pivotally connected to the 'front' of the tee body
Implementation Method 2
the latch assembly comprises a latch tab having an ear; and a catch defined as a curve in the ear of the latch tab, wherein the catch is configured to engage the catch pin when the door is in a closed position
Implementation Method 3
The snaking bar is configured to engage the U-Bolt, which can selectively be used to engage or disengage the door
