Pivoting Ramp Frame With Linkage Knob For Adjustable Curvature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toy ramps and tracks do not include a pivoting frame that can adjustably support a bendable ramp surface to vary the height and curvature through rotation of a single knob member, limiting the versatility and fun of toy vehicle pathways.
Innovation Solution
A toy ramp design featuring a frame with pivoting arm members and assemblies that allow the bendable ramp to adjust between nearly vertical and horizontal positions via a single knob-controlled mechanism, incorporating a stop mechanism for locking angles and a linkage system for unified arm movement, with a flexible plastic ramp surface secured by arm members and clamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single knob member controls the pivoting of arm members to adjust ramp position, then ease of operation is improved, but device complexity increases due to the linkage system required to connect multiple arm members
Solution Approach 1:
Multiple arm members are mechanically linked together through a common pivoting assembly and linkage system, allowing them to move in unison as a single unit. This merging of multiple components into a coordinated system enables control through a single knob member while maintaining synchronized adjustment of all arm members supporting the ramp.
Solution Approach 2:
The single knob member serves multiple functions: it simultaneously controls the pivoting of multiple arm members, adjusts the ramp's position and angle, and maintains synchronized movement across the entire support structure. This multi-functionality reduces the number of separate controls needed while achieving comprehensive adjustment capability.
2Adaptability or versatility
If the ramp surface is made bendable to vary curvature, then adaptability is improved, but reliability decreases due to potential damage from heavy loads
Solution Approach 1:
The ramp surface is designed as a bendable or flexible element that can dynamically change its curvature and shape in response to the position of the arm members. This dynamic capability allows the ramp to adapt to different launch angles and trajectories while being supported by the rigid, adjustable arm member structure that provides stability under load.
Solution Approach 2:
The ramp utilizes a flexible sheet or panel material that can bend and curve to create various ramp profiles. This flexible surface is supported by the rigid arm members and pivoting assembly, allowing the ramp to achieve desired curvatures for different toy vehicle launches while the underlying rigid structure maintains reliability and prevents damage from heavy loads.
3Stability of the object's composition
If multiple arm members are used to support the ramp, then stability is improved, but device complexity increases due to the pivoting assemblies required
Solution Approach 1:
Multiple arm members are merged into a coordinated system through a common pivoting assembly and linkage mechanism. This merging allows all arm members to move together in unison when the single knob member is rotated, providing stable support for the ramp while reducing the number of independent controls and simplifying the overall adjustment mechanism.
Solution Approach 2:
The pivoting assemblies are strategically positioned at specific locations along the arm members to optimize stability. The asymmetric arrangement of pivot points and linkage connections ensures proper mechanical advantage and stable support distribution, allowing the multiple arm members to work together effectively while maintaining manageable complexity.

AI summary
A toy which simply yet uniquely varies the height and curvature of a flexible ramp uniquely supported on a pivoting ramp frame. The toy includes a frame for resting on a horizontal surface, spaced apart horizontally and extending upwardly from the frame defining an open area therebetween above the frame, and first and second pivoting assemblies at the frame engaging first and second arm members for adjustably pivoting the arm members between varying angles with respect to the frame. A bendable ramp is adjustably supported at the frame, secured to the arm members and sitting in the open area defined by the arm members.
