Container Holder Roller Dynamics for Rotation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container holders are limited in their ability to securely hold a wide range of container sizes and fail to effectively prevent container rotation, requiring users to manually stabilize the container to screw or unscrew caps.
Innovation Solution
A container holder design featuring rollers with a rotational center line tangential to the recess's central axis, allowing the rollers to tilt and increase frictional force when a rotational force is applied, combined with a biasing member and sliders for enhanced stability and contact with the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support member is pushed onto a side of the container with limited frictional force, then the container can be inserted and removed easily, but the container rotation cannot be prevented effectively
Solution Approach 1:
The support member is designed to be movable rather than fixed, allowing it to dynamically adjust its position and frictional force based on container size. The member can move radially to accommodate different container diameters while maintaining adequate frictional contact, thus preventing rotation without requiring excessive insertion force.
Solution Approach 2:
The frictional force parameter is made variable through the movable support member design. By changing the position of the support member along the radial direction, the frictional force between the support member and container can be adjusted to match different container sizes, ensuring effective rotation prevention across various container dimensions.
2Stability of the object's composition
If the support member is urged into the recess with strong spring force, then the container can be held firmly without rattling, but the frictional force remains limited and rotation prevention is insufficient
Solution Approach 1:
The solution moves from considering only radial positioning to incorporating angular/orientational adjustment. The support member can change its orientation angle relative to the container, allowing it to wrap around the container more effectively. This angular dimension adds a new degree of freedom for increasing frictional contact area and pressure, thereby improving rotation prevention while maintaining container stability.
Solution Approach 2:
The support member is designed with dynamic capabilities in both radial and angular directions. It can simultaneously adjust its radial position and orientation angle to optimally contact the container, creating adaptive frictional forces that prevent rotation while maintaining stability for various container sizes and shapes.
3Reliability
If pressure pieces are used to support the container rotationally fast, then the container can be secured against rotation, but the user must forcibly push the container into the recess and the range of container sizes is limited
Solution Approach 1:
The support member is designed as a dynamic, movable component that can adapt its position and orientation to accommodate various container sizes. Unlike fixed pressure pieces, it can move radially and adjust its angle to match different container dimensions, providing effective rotation prevention across a wider range of sizes without requiring forced insertion.
Solution Approach 2:
The movable support member serves multiple functions: it provides radial support, angular adjustment, and adaptive frictional contact for containers of various sizes. This universal design replaces the need for size-specific pressure pieces, allowing a single mechanism to effectively secure different container types without requiring forced insertion.
