Adjustable Dolly With Telescopic Posts and Crossbars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dollies fail to adapt to various moving tasks, requiring multiple dollies and increasing time and storage space, as they are not adaptable to different object types and tasks.
Innovation Solution
An adjustable dolly with a rectangular platform and pivotally mounted posts and crossbars, featuring a locking mechanism and telescopic arms, allowing for transformation into different configurations to accommodate various objects by extending or retracting posts and crossbars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dollies are used to accommodate different object types and tasks, then the adaptability to various moving tasks is improved, but the storage space required and time to find the correct tool increase
Solution Approach 1:
The dolly is designed with adjustable posts and crossbars that can be configured to accommodate different object types and sizes. The posts can be extended or retracted, and crossbars can be added or removed, allowing a single dolly to serve multiple functions for carrying boxes, furniture, and other materials, eliminating the need for multiple specialized dollies.
Solution Approach 2:
The dolly incorporates movable and adjustable components including telescopic posts and detachable crossbars that can be dynamically reconfigured. This dynamic adjustability allows the dolly structure to adapt to different loading requirements and object dimensions, providing versatility while maintaining a compact form when not in use.
2Adaptability or versatility
If multiple dollies are used to accommodate different object types and tasks, then the adaptability to various moving tasks is improved, but the time to find the correct tool increases
Solution Approach 1:
By designing a single dolly with adjustable posts and crossbars that can accommodate various object types, the system eliminates the need for multiple specialized dollies. This universality ensures that only one dolly is needed for all moving tasks, significantly reducing the time spent searching for the appropriate tool.
3Reliability
If posts and crossbars are added to provide rigidity and keep objects on the platform, then the stability and security of object transport is improved, but the device complexity increases
Solution Approach 1:
The rigidity system is divided into separate modular components: individual posts that can be independently extended or retracted, and detachable crossbars that can be added or removed as needed. This segmentation allows the stability features to be incorporated only when required, reducing overall device complexity while maintaining reliability during use.
Solution Approach 2:
The posts and crossbars are designed as movable rather than fixed components. The telescopic posts can be extended to provide rigidity when needed and retracted when not required, while crossbars can be attached or detached based on the specific transport task. This dynamic approach provides stability only when necessary, reducing structural complexity.
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 efficient and secure storage or carrying of objects by allowing the dolly to be transformed into different formations, reducing the need for multiple dollies and optimizing storage space while accommodating diverse objects.
Implementation Method 1
a locking pin connected to said locking slider, wherein the locking pin is locked and released by movement of the locking slider, which slider exerts force against said post storage when moved into a locked position by camming against the post storage
Implementation Method 2
an internal segment slidably extendable from said external segment

AI summary
A dolly for moving objects having a rectangular platform with casters mounted underneath, having four posts which may be raised from the base and locked into an upright position. The posts further have crossbars pivotally mounted thereon, which are releasably connectable to the crossbars of adjacent posts, to form a supportive railing around the tops of the posts. The posts may further be connected by means of telescopic arms, which are pivotally connected to one crossbar, and extendible to another crossbar, wherein they may be releasably connected by means of a knob at the end of the telescopic arm being pressed into an inverted teardrop-shaped receptacle.
