Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unique designs are created for each excavator and deck type, then compatibility with specific mast sizes and geometries is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements a universal mast device design that can accommodate multiple mast sizes and geometries through a standardized base plate and mast plate assembly. The device uses adjustable connection mechanisms including replaceable pins and spacing elements that allow the same fundamental design to adapt to various mast configurations without requiring unique designs for each excavator type.
Solution Approach 2:
The mast device is divided into modular components including a base plate, mast plates, connection plates, pins, and spacing elements. This segmentation allows individual components to be adjusted or replaced to accommodate different mast specifications while maintaining the overall structural integrity of the assembly.
2Stability of the object's composition
If fixed unique designs are used for each mast type, then structural stability is improved, but adaptability to varied mast geometries deteriorates
Solution Approach 1:
The mast device incorporates dynamic adjustment capabilities through replaceable pins of varying diameters, adjustable spacing elements, and interchangeable connection plates. These dynamic elements allow the rigid mast structure to be configured for different mast geometries while maintaining structural stability through proper mechanical fastening and alignment.
3Adaptability or versatility
If interchangeable pins with varied diameters are implemented, then adaptability to different mast specifications is improved, but device complexity increases
Solution Approach 1:
The patent utilizes parameter changes by providing pins with varied diameters and spacing elements with adjustable dimensions. These parameter variations allow the same fundamental connection mechanism to accommodate different mast specifications. The standardized interface design ensures that despite parameter variations, the overall device architecture remains consistent and manageable.

AI summary
A variable connection size excavator mast device provides attachment for varied mast sizes and geometries eliminating need for a unique design for each excavator and deck type. The device includes a base plate and a pair of mast plates. The pair of mast plates is coupled to and extends upwardly from the mast plate. The mast plates are perpendicular to the base plate and parallel to each other. A fixed pin is coupled to and extends between the mast plates. A sliding pin is adjustably coupled to and extends between the mast plates. The sliding pin is parallel to the fixed pin.
