Stretch Film Dispenser Auxiliary Stand Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stretch film dispensers tip over due to their small base and heavy, high-positioned film rolls, making them unstable when placed on the ground.
Innovation Solution
An auxiliary stand device is integrated into the stretch film dispenser, with a wider base extension that matches the bottom side of the existing base, preventing tipping by increasing the overall footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the base is made small to reduce device size, then the device becomes more compact and easier to store, but the device tips over easily when placed on the ground
Solution Approach 1:
The patent extends the base in a horizontal dimension by adding an auxiliary stand that protrudes outward from the main base. This dimensional extension increases the footprint and stability without increasing the vertical height or the core volume of the dispenser body, effectively resolving the contradiction between compact size and stability.
Solution Approach 2:
The base is segmented into two functional parts: the main base that supports the dispenser body and the auxiliary stand that provides additional stability. This segmentation allows each part to perform its specific function optimally - the main base maintains compactness while the auxiliary stand extends the support footprint to prevent tipping.
2Stability of the object's composition
If the auxiliary stand device is added to increase stability, then the device becomes more stable when placed on the ground, but the device complexity increases
Solution Approach 1:
The auxiliary stand is merged with the handle bar structure, combining two functional elements into one integrated component. The stand extends from the handle bar and serves dual purposes: providing structural support for the handle bar and extending the base footprint for stability. This merging eliminates the need for separate auxiliary support structures, reducing overall device complexity while maintaining stability.
Solution Approach 2:
The handle bar is designed with multi-functionality, serving both as a gripping handle for user operation and as a structural support for the auxiliary stand. This universal design allows a single component to fulfill multiple functions, avoiding the need for additional separate parts and thereby minimizing device complexity while achieving the stability goal.

AI summary
A stretch film dispenser of the present invention is equipped with an auxiliary stand device. The stretch film dispenser includes a base, a curved handle bar, which has a handle on a distal end thereof, fixed to a circumference of the base, and a shaft, which has a handle on a distal end thereof, fixed to a top of the base to mount a stretch film roll thereon. The auxiliary stand device is fixed to the handle bar. A bottom side of the auxiliary stand device is substantially even with a bottom side of the base, and a width of the auxiliary stand device is greater than a diameter of the handle bar therefore a bottom size of the stretch film dispenser increases to prevent the stretch film dispenser from tipping over.
