Transport Vehicle Holder Layout for Vertical Downsizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport vehicles are vertically oversized due to protruding components, such as grippers and belt fasteners, which hinder efficient downsizing and compactness.
Innovation Solution
A transport vehicle design featuring a holder with first and second holder members located below a horizontal support plate, a holder drive positioned vertically below the support, and elongated member fasteners that protrude downward, allowing for efficient vertical downsizing and reduced component placement above the support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If grippers and belt fasteners protrude from the holder structure, then the holder can perform its holding and fastening functions, but the vertical size of the transport vehicle increases
Solution Approach 1:
The patent repositions components from protruding in multiple directions to being integrated within the holder's internal volume. The belt fastener is moved to protrude from the bottom surface rather than the top, and the gripper mechanism is arranged to operate within the holder's internal space, effectively utilizing the vertical dimension more efficiently and reducing the overall vertical envelope of the transport vehicle.
Solution Approach 2:
The patent integrates the gripper mechanism and belt fastener within the holder's structural volume. The gripper fingers are positioned to operate within the internal space of the holder, and the fastening mechanism is nested such that components are contained within or integrated into the holder body, reducing the need for additional protruding elements.
2Length of stationary object
If components are arranged to protrude from the holder, then the holder can access and manipulate the article, but the distance between the holder and lifting drive increases
Solution Approach 1:
Instead of having the belt fastener protrude upward from the top surface of the holder (as in conventional designs), the patent inverts the arrangement so that the belt fastener protrudes downward from the bottom surface. This allows the holder to be positioned closer to the lifting drive while still providing adequate space for the fastening mechanism to operate.
3Volume of stationary object
If the holder structure is enlarged to accommodate protruding components, then all components can be housed, but the transport vehicle cannot be downsized vertically
Solution Approach 1:
The patent changes the spatial parameters of component arrangement by repositioning the belt fastener to protrude from the bottom surface and arranging the gripper mechanism to utilize internal volume rather than external protrusion. This reconfiguration maintains adequate component housing volume while significantly reducing the vertical dimension of the overall holder assembly.
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
This design enables the transport vehicle to be compacted vertically, with the holder and lifting drive positioned closer together, enhancing overall vertical downsizing and reducing interference with the lifting mechanism.
Implementation Method 1
a lifting drive that winds and unwinds the elongated member to lift and lower the holder
Implementation Method 2
The elongated member fastener fastens the elongated member to the support
