Transport Roller With Below-Object Tipping Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport rollers require lifting and cumbersome movement of heavy objects, such as large plant pots, and often lack stability on uneven surfaces, making it difficult to move them between locations without risking tipping or damage.
Innovation Solution
A transport roller system with a support plate and rollers positioned below the object, allowing for a tipping point under the object, which enables easy tilting and movement using a drawbar, combined with adjustable support feet for stability on various surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If heavy objects are moved using conventional transport rollers, then the objects can be transported from one location to another, but significant lifting force and cumbersome movement are required
Solution Approach 1:
The patent inverts the conventional approach by positioning the tipping point below the object rather than above it. This inversion allows the object to be tilted forward onto the rollers naturally, eliminating the need for lifting. The support plate extends below the object's center of gravity to create this sub-object tipping point, fundamentally changing the movement mechanism from lift-and-move to tilt-and-roll.
Solution Approach 2:
The patent introduces a vertical dimension element by extending the support plate below the object. This creates a three-dimensional support structure where the support plate has portions both above and below the object's center of gravity, enabling the unique below-object tipping point mechanism that reduces lifting requirements.
2Adaptability or versatility
If transport rollers are used on uneven surfaces, then mobility is maintained, but stability is compromised and tipping risks increase
Solution Approach 1:
The patent employs adjustable support feet that can dynamically adapt their position and orientation to match uneven surfaces. These support feet are configured to contact the ground at angles suitable for the specific surface conditions, allowing the transport roller to maintain stability on both flat and uneven terrain while preserving the below-object tipping point configuration.
3Force
If the support plate extends below the object to create a below-object tipping point, then tilting force is reduced, but the device complexity increases
Solution Approach 1:
The support plate serves multiple functions: it supports the object from below, creates the below-object tipping point for reduced tilting force, and provides attachment points for adjustable support feet. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity despite the extended below-object configuration.
