Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trampolines lack a compact design to replicate the dynamic response and angled bed configuration of large trampoline parks in smaller backyard settings, limiting the recreational experience and safety for users.
Innovation Solution
A trampoline design featuring an upper frame with differently sized members, pulldown springs mounted between the trampoline bed and a lower frame, and a trampoline bed reinforcement panel that creates an obtuse folding angle, distributing force to separate the bed into inclined and horizontal areas, enhancing user dynamics and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a contoured profile with angled trampoline beds is implemented, then the dynamic response and user experience are improved, but the device size and complexity increase making it unsuitable for backyard settings
Solution Approach 1:
The patent implements a nested frame structure where an inner frame is positioned within an outer frame, allowing the contoured bed profile to be achieved in a compact configuration. The pulldown springs connect the bed to the inner frame, creating the angled profile without requiring a large overall device footprint, thus enabling park-like dynamics in a backyard-friendly size.
Solution Approach 2:
The patent uses pulldown springs to create vertical dimension changes in the bed profile, forming angled sections that rise from the horizontal bed surface. This dimensional approach allows the contoured profile to be achieved through vertical adjustment rather than horizontal expansion, maintaining compact device size while improving dynamic response.
2Reliability
If pulldown springs are added to create angled bed sections, then the force distribution and safety are improved, but the device complexity increases
Solution Approach 1:
The patent segments the bed into distinct horizontal and angled sections using pulldown springs at specific locations. This segmentation allows force to be distributed across multiple spring attachment points rather than concentrated in one area, improving safety while adding only the necessary minimal components to achieve the segmented profile.
Solution Approach 2:
The patent applies pulldown springs only at specific locations where the bed transitions from horizontal to angled sections, rather than uniformly across the entire bed. This localized application creates the desired force distribution and safety improvements while minimizing the increase in overall device complexity.
3Adaptability or versatility
If the bed is separated into inclined and horizontal areas, then user dynamics are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent uses standard pulldown spring components that serve multiple functions: they provide the angled profile, distribute force for safety, and create the horizontal to inclined transition. This multi-functionality allows the same component to address multiple design requirements, reducing manufacturing complexity despite the enhanced user dynamics.

Function Achieved in This Case
The solution provides a compact trampoline setup that mimics the angled bed configuration of larger parks, improving user dynamics and safety by distributing force effectively across the trampoline bed, encouraging users to move towards the center and enhancing the overall jumping experience.
Implementation Method 1
The pulldown spring is held in tension at a trampoline bed reinforcement panel. The pulldown spring biases the trampoline bed reinforcement panel toward the lower frame.
Implementation Method 2

AI summary
A trampoline has an upper frame having a first upper frame member and a second upper frame member. The trampoline bed is held in tension between and extended between the first upper frame member and the second upper frame member. The first upper frame member is a different height than the second upper frame member. Trampoline bed springs connect between the upper frame and the trampoline bed. A pulldown spring is mounted between the trampoline bed and a lower frame. The pulldown spring is held in tension at a trampoline bed reinforcement panel. The pulldown spring biases the trampoline bed reinforcement panel toward the lower frame. A folding angle is formed on the trampoline bed.
