Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a hydraulic pump assembly and hydraulic valve assembly are used for lifting and reversing, then the number of intermediate transmission links is reduced and operating noise is lowered, but asynchronous lifting occurs due to network communication signals and software program loopholes
Solution Approach 1:
The patent replaces the hydraulic control system with a mechanical transmission system consisting of a lifting and reversing gearbox, planetary reducer, and gear train. This mechanical substitution eliminates the reliance on network communication signals and software control, providing more reliable and synchronous operation through pure mechanical power transmission from the servo motor through the planetary reducer and gear train to simultaneously control both lifting and reversing actions.
2Device complexity
If a chain drive system is used for power transmission, then the structure is simplified, but chain stretching causes looseness and inaccurate wheel starting and stopping
Solution Approach 1:
The patent replaces the chain drive system with a direct mechanical gear transmission system. The power transmission path goes from the servo motor through the planetary reducer directly to the lifting and reversing gearbox, eliminating the chain drive entirely. This direct mechanical connection ensures precise power transmission without chain stretching, achieving accurate wheel starting and stopping positions through the rigid gear train connection.
3Ease of manufacture
If a hydraulic reversing and lifting device is used, then installation and maintenance become more convenient, but overloading occurs during reversing causing falls or deflections
Solution Approach 1:
The patent replaces the hydraulic reversing and lifting device with a mechanical transmission system consisting of a lifting and reversing gearbox with planetary reducer and gear train. This mechanical system provides inherent load-bearing capacity through the robust gear meshing and planetary reducer structure, preventing overloading during reversing operations. The mechanical connection ensures stable power transmission and prevents falls or deflections that can occur with hydraulic systems under excessive load.
