Freight Compartment Tiering Structure With Embedded Belt Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tiering devices for freight compartments occupy a large amount of space within the compartment, affecting the loading and unloading of goods due to the use of transmission parts like synchronous belts and threaded rods.
Innovation Solution
The design embeds a synchronous belt within the sidewall of the freight compartment, utilizing a vertical guide track with a belt guide channel and a sliding mount system that allows the support member to be adjusted in height without occupying additional space, using an electric motor-driven mounting shaft and pretensioning mechanism for tension adjustment.

Engineering Contradiction Analysis
1Extent of automation
If a synchronous belt is used as a transmission part to achieve automatic lifting and lowering of support cross beams, then the lifting and lowering operation is automated, but the synchronous belt occupies space inside the freight compartment and affects loading/unloading goods
Solution Approach 1:
The synchronous belt is nested within the sidewall structure by creating a belt channel that guides the belt through the sidewall thickness. The belt runs vertically within this channel, allowing the transmission mechanism to be embedded in the sidewall rather than protruding into the freight compartment space.
Solution Approach 2:
The transmission mechanism is moved from the horizontal dimension (protruding into the compartment) to the vertical dimension (embedded in the sidewall thickness). The belt channel extends vertically through the sidewall, allowing the synchronous belt to operate in the thickness dimension of the sidewall rather than occupying the compartment's internal volume.
2Volume of moving object
If the synchronous belt is embedded within the sidewall to reduce space occupation, then the space inside the freight compartment is reduced, but the sidewall thickness must be sufficient to accommodate the belt channel
Solution Approach 1:
The sidewall is segmented into functional zones: an external drive portion where the motor is mounted, a belt channel portion that guides the synchronous belt, and an internal support portion. This segmentation allows the belt to be routed efficiently through the sidewall thickness, minimizing the required thickness while maintaining structural integrity.
Solution Approach 2:
The sidewall is designed with localized features including a belt channel with specific cross-sectional shape and dimensions, snap-in ports for positioning, and reinforcement elements. These local modifications optimize the belt embedding while minimizing the overall sidewall thickness requirement.
3Volume of moving object
If a support plate is used instead of support cross beams to reduce space occupation, then fewer lifting mechanisms are needed (only at four corners), but the support plate may have limited load distribution capability
Solution Approach 1:
The support plate and support cross beam functions are merged into a single integrated support member. This hybrid structure combines the area distribution advantage of plates with the structural strength of beams, providing both broad load distribution and high load-bearing capacity while requiring lifting mechanisms only at the corner positions.

AI summary
The present invention provides a tiering device for a freight compartment, which pertains to the technical field of logistic and transportation equipment. It solves the problem in the prior art that existing tiering devices for a freight compartment occupy a relatively large space inside the freight compartment. The tiering device for a freight compartment according to the present invention comprises: a sidewall of the freight compartment, a transmission part, and a vertical guide track; the transmission part lift/lower support members, the support members forms placement area for goods. Half of the transmission part is buried inside a belt guide channel on the vertical guide track, the other half is located inside the vertical guide track or is flush with the groove opening of the vertical guide track. The present invention has the advantage of occupying less space inside the freight compartment, thus facilitating loading/unloading goods to/from the freight compartment.
