Transport Vehicle Holder With Movable Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport vehicles face issues where the holder assembly may accidentally open due to malfunctions or vibrations, causing the container to slip and potentially leading to the article being held to fall off during transport.
Innovation Solution
The transport vehicle incorporates a holder with movable holding parts and a driver that includes a mount area and protrusion to securely hold the article's handle, restricting its movement and preventing slipping, along with sensors to ensure proper placement and detection for accurate holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple holder assembly with tabs is used to hold the container, then the device complexity is reduced, but the reliability of preventing the article from slipping off deteriorates
Solution Approach 1:
The holder is divided into multiple independent holding parts (first holding part and second holding part) that can move relative to each other. Each holding part has independent tabs that can be positioned to engage with the container flange, allowing the system to maintain reliability while keeping each individual component simple.
Solution Approach 2:
The holding parts are made movable relative to each other, transitioning from a static simple structure to a dynamic system. The holding parts can move between a held state (engaging the flange) and a separated state, allowing the holder to adapt to different conditions while maintaining secure engagement when needed.
2Adaptability or versatility
If the holder assembly tabs are made movable to adjust holding position, then the adaptability improves, but the likelihood of accidental opening due to malfunction or vibration increases
Solution Approach 1:
The holding parts are designed with features that prevent accidental opening before it can occur. The tabs are positioned and dimensioned to engage deeply with the flange, and the holding parts are constrained by the holder body to prevent unintended movement. This preliminary design feature counteracts the potential harmful effect of vibration or malfunction before they can cause opening.
Solution Approach 2:
The holder uses controlled dynamics where holding parts can move intentionally for adjustment but are constrained to prevent accidental movement. The movable design allows adaptability while the constraint mechanism ensures that only intentional actions (not vibrations or malfunctions) can change the holding state.
3Reliability
If multiple holding parts are used to secure the container from multiple directions, then the article holding stability improves, but the device complexity increases
Solution Approach 1:
The holder is segmented into multiple holding parts that work together to secure the container. Each holding part has a relatively simple tab structure, but the combination of multiple parts provides enhanced stability and reliability through multi-directional engagement with the flange.

AI summary
A holder includes a holder body, a holding part supported in a manner movable in a first direction relative to the holder body, and a holding part driver that drives the holding part. The holding part includes a supported portion supported by the holder body, a base extending downward from the supported portion, and an extension extending from the base in the first direction. The extension includes, on an upper surface of the extension, a mount area on which the lower surface of the handle is placeable. The extension includes a protrusion located opposite to the base across the mount area in the first direction. The protrusion protrudes upward from the mount area.
