Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driving portions are manually positioned according to slope conditions, then power distribution can be adjusted for different working conditions, but labor and time costs increase significantly
Solution Approach 1:
The patent applies the dynamics principle by making the driving portions movable along the rail rather than fixed at specific positions. The driving portions can be freely moved to different locations and quickly fixed, enabling dynamic adaptation to various slope conditions without manual repositioning for each working condition. This resolves the contradiction by providing adaptability through movement rather than through time-consuming manual adjustment.
Solution Approach 2:
The patent implements self-service by enabling the driving portions to automatically adapt to different slope conditions through their movable design. The system allows operators to quickly reposition driving portions without requiring complex planning or significant labor input, making the power distribution system self-adaptable to varying working conditions. This reduces the labor and time costs while maintaining adaptability.
2Adaptability or versatility
If driving portions are fixed at specific positions, then power distribution is optimized for certain conditions, but the system cannot adapt to variable slopes and parking adjustments are needed
Solution Approach 1:
The patent transforms the static power distribution system into a dynamic one by allowing driving portions to move along the rail. This enables the system to adapt to variable slopes and different parking positions without requiring complex adjustment mechanisms. The simplicity of moving and fixing driving portions at different locations provides adaptability while avoiding increased system complexity.
3Reliability
If rail installation errors cause non-parallel rails, then lateral forces are generated on the rail, but increasing rail strength to prevent bending failure increases equipment cost
Solution Approach 1:
The patent extracts the problem source by allowing driving portions to move freely along the rail rather than being fixed at specific positions. This movement capability enables the system to accommodate rail installation errors and non-parallel conditions without generating excessive lateral forces. By removing the constraint of fixed positioning, the rail does not need to be overly strengthened, thus avoiding increased weight and cost while maintaining safety.
4Adaptability or versatility
If additional driving portion units are added at front and back sides, then power distribution flexibility during slope operation is improved, but integral length and whole machine weight increase
Solution Approach 1:
The patent applies dynamics by enabling existing driving portions to move to different positions along the rail rather than adding more driving portion units. This movable design provides power distribution flexibility during slope operation without increasing the integral length of the overhead monorail system. The same number of driving portions can serve multiple positions, achieving adaptability without extending the overall system length.

AI summary
The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods. Overhead monorail driving portions have four paths for transmitting a driving force to the hoisting beam, the frame-shaped pull rods directly transmit the driving force of the driving portions in positions far away from the hoisting beam to the hoisting beam, the objective is to reduce an accumulated peak value of the driving force of the driving portion in a mode of serial-parallel arrangement of the overhead monorail driving portions, the problem of horizontal direction bending failure of the rail caused by the driving portions in an operation process of an overhead monorail is solved, and the reliability and adaptability of overhead monorail transportation equipment are improved.
