Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the cargo tool is mounted on the vehicle using conventional methods, then the carrying capacity is improved, but the joint stability deteriorates due to wear from vibrations and environmental factors
Solution Approach 1:
The patent employs a dynamic gap elimination mechanism where the eccentric member rotates relative to the connecting assembly under the action of the eccentric drive member. This dynamic adjustment allows the abutment surface to continuously contact and press against the connecting assembly, automatically eliminating wear gaps that form during operation. The mechanism transforms from a static connection to a dynamic self-adjusting connection that maintains stability despite wear.
Solution Approach 2:
The eccentric drive member is configured to automatically drive the eccentric member to rotate, creating a self-service mechanism that eliminates wear gaps without external intervention. The system uses the existing operational forces and the eccentric geometry to automatically adjust and maintain the abutment contact, making the stability maintenance function self-powered and integrated into the normal operation of the cargo tool.
2Productivity
If the cargo tool operates for long periods, then the productivity is improved, but the wear at joints increases, affecting service life
Solution Approach 1:
The eccentric drive member is pre-configured to automatically activate and eliminate wear gaps before they can significantly impact joint stability. By anticipating the formation of wear gaps during prolonged operation, the mechanism proactively adjusts the abutment contact, preventing the accumulation of wear damage and extending the service life of the cargo tool while maintaining continuous productivity.

AI summary
The present invention discloses an externally connected cargo tool for a vehicle, including a connecting assembly, a support assembly, and an eccentric assembly disposed therebetween. The eccentric assembly includes an eccentric member and an eccentric drive member. Two ends of the eccentric member are rotatably connected to the support assembly, and a middle portion of the eccentric member abuts against the connecting assembly. The eccentric drive member is configured to drive the eccentric member to rotate, eliminating a wear gap at an abutment between the eccentric member and the connecting assembly, thereby resolving the problem of poor stability due to wear at a joint between the cargo tool and the vehicle when the cargo tool carries goods.
