Cargo Loading System Height Adjustment Guide Rail Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for loading and unloading cargo from transportation vehicles require manual labor, especially when the vehicle is inclined, making the process cumbersome and labor-intensive, as workers need to enter the cargo box to move cargo to its desired location.
Innovation Solution
A cargo loading system featuring a frame with height adjustment, guide rails, a movable body with driving rollers, and a drive mechanism that allows cargo to be loaded and unloaded externally, using a combination of guide rails and a drive motor to move cargo within the cargo box without requiring workers to enter it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cargo is loaded into a sealed cargo box using conventional methods, then cargo can be transported in an enclosed manner, but workers must enter the cargo box to push and move cargo, making the work burdensome and requiring significant manual labor
Solution Approach 1:
A movable body with driving rollers serves as an intermediary device between the external loading area and the interior of the cargo box. This movable body can be pushed from outside the cargo box to transport cargo deep inside the sealed box, eliminating the need for workers to enter the cargo box while maintaining enclosed transportation.
2Adaptability or versatility
If cargo is loaded into a cargo box when the vehicle is stopped on an inclined location, then cargo can be transported from any stopping location, but cargo tends to slide or fall due to gravity, making loading and unloading difficult and requiring more manpower
Solution Approach 1:
The height adjustment means adjust the height of the support plate and second guide rail to match the loading height of the cargo box regardless of the vehicle's stopping location or ground inclination. This creates an equipotential loading interface that prevents cargo from sliding or falling during loading, enabling operation from any stopping location without additional manual effort to prevent cargo movement.
3Productivity
If a crane is used to load cargo vertically into a cargo box, then loading speed can be improved, but the roof of the cargo box prevents vertical loading
Solution Approach 1:
Instead of vertical loading from above (which is blocked by the cargo box roof), the system uses horizontal loading through the entrance combined with the movable body that travels along guide rails into the depth of the cargo box. This dimensional change from vertical to horizontal+depth movement enables loading without crane while achieving deep cargo placement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient loading and unloading of cargo from any stopping location, reducing manual labor and preventing cargo from sliding or falling, even when the cargo box is inclined, by allowing external operation and secure movement of cargo within the sealed box.
Implementation Method 1
a movable body which is provided with driving rollers on the bottom thereof so that it can move along the first guide rail and the second guide rail
Implementation Method 2
a drive means which is disposed on the rear side of the support plate so as to move the movable body along the first guide rail and the second guide rail and includes a wire configured to be connected to one side of the movable body, a winding unit configured to wind the wire, and a drive motor configured to drive the winding unit
