Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional integrated transport systems are used with multiple actuators for pivoting the mower, then the transport function is achieved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the transport function from the main mower structure by using a separate transport trailer. The mower can be detached from its normal operating position and loaded onto the transport trailer, which has its own independent wheels and support structure. This separation eliminates the need for complex pivoting actuators on the mower itself, as the transport trailer handles all transport movements independently.
Solution Approach 2:
The transport trailer acts as an intermediary between the mower and the towing vehicle during transport operations. Instead of the mower directly attaching to and being towed by the vehicle in transport mode, the trailer serves as a mediating platform that receives the mower, provides its own transport capabilities, and can be independently towed to the field location.
2Length of stationary object
If separate transport trailers are used to carry the mowing device, then the transport width limitation is resolved, but the operational cost increases due to separate purchase, maintenance, and transport
Solution Approach 1:
The patent merges the transport function with the existing mower structure by integrating a foldable support structure and pivoting mechanism directly into the mower assembly. The transport wheels are integrated into the mower's frame, allowing the mower to support itself in transport mode without requiring a completely separate transport trailer. This combination reduces the need for separate transport equipment while maintaining the ability to reduce transport width.
Solution Approach 2:
The mower is designed with multi-functionality, where the same structural components serve both cutting operations and transport functions. The foldable support structure and pivoting mechanism enable the mower to transition between operating mode and transport mode using its own integrated systems, eliminating the need for dedicated separate transport equipment and reducing overall operational costs.
3Adaptability or versatility
If the transport system is attached to the trail frame of the mower, then the transport function is integrated, but the added weight creates large inertia that causes operator discomfort during quick field position changes
Solution Approach 1:
The patent implements dynamic characteristics in the transport system through foldable support structures and pivoting mechanisms that allow the mower to adapt its configuration. The transport wheels and support elements can be folded or repositioned to minimize weight during non-transport operations, and the pivoting capability allows quick adjustment between field positions without carrying the full transport system weight continuously. This dynamic design reduces the effective inertial mass during rapid field maneuvers.

AI summary
An agricultural mowing device (120) including a tongue (122) configured for connecting to an agricultural vehicle (110), a trail frame (124) rotatably connected to the tongue about an axis of rotation (A1), a first trail-frame wheel (126) and a second trail-frame wheel (128) each being rotatably connected to the trail frame, and a cutter bar (130) connected to the trail frame. The mowing device also includes a transport system (200) that has a transport frame (202) rotatably connected to the tongue and a first transport wheel (204) and a second transport wheel (206) each being rotatably connected to the transport frame. In the transport position, the first and second transport wheels support the trail frame. The first transport wheel is radially closer to the axis of rotation of the trail frame than the front end of the cutter bar in the transport position.
