Eccentric Bearing Platform Locking for Semi-Trailer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semi-trailer vehicles face difficulties in maintaining the stability and precise positioning of movable platforms during load carriage due to inadequate locking mechanisms, often requiring multiple workers and leading to inefficiencies and potential damage to wheel axles.
Innovation Solution
A structure featuring a main frame on wheels with a first platform for forward and backward movement, a locking channel, a second platform with a reciprocating motion, and an eccentric bearing assembly that ensures precise positioning and secure locking of the first platform within the locking channel, allowing single-person operation and reduced load on locking systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning and locking is performed by workers during load carriage, then the platform can be positioned and fixed, but multiple employees are required and the process is inefficient
Solution Approach 1:
The locking mechanism automatically positions and locks the platform using the load itself as the actuating force. The system self-regulates through the interaction between the bearing assembly, locking channel, and platform weight, eliminating the need for manual intervention and multiple workers during the locking operation.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated mechanical system that uses the platform's own weight and the load to drive the locking mechanism. The bearing assembly converts the reciprocating motion into automatic locking action, substituting human effort with a self-actuating mechanical system.
2Reliability
If locking pins are mounted in the middle to prevent damage to wheel axles, then wheel axles are protected, but positioning and fixing of the movable platform becomes difficult and locks fail repeatedly
Solution Approach 1:
The locking function is segmented into multiple components: the bearing assembly for positioning, the locking channel for guidance, and the locking pins for securing. This segmentation allows each component to perform its specific function optimally - the bearing handles positioning while the pins handle locking, resolving the conflict between axle protection and positioning difficulty.
Solution Approach 2:
The bearing assembly acts as an intermediary between the platform and the locking pins. It converts the reciprocating motion of the platform into controlled movement that properly engages the locking pins in the locking channel, mediating between the platform's movement and the locking mechanism to ensure reliable locking without damaging wheel axles.
3Adaptability or versatility
If bearings are not properly contained in the housing during platform movement, then platform movement is possible, but bearings leave the housing causing undesirable situations in positioning and fixing
Solution Approach 1:
The bearing assembly is nested within the housing structure, with the bearing contained inside a protective housing that guides its movement. This nested arrangement allows the bearing to move reciprocally for platform positioning while remaining contained and protected, preventing it from leaving the housing during operation.
Solution Approach 2:
The bearing assembly is designed to dynamically move back and forth in a controlled manner within the housing during platform positioning, then become statically locked in place when the locking mechanism engages. This dynamic design allows necessary movement while ensuring the bearing remains contained and reliable throughout the operation.
