Foldable Trampoline Frame Rod Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable trampolines face issues with strong elastic contraction forces causing frame rods to eject or clamp users, and require forceful operation to maintain the folded position, posing safety risks during folding and unfolding.
Innovation Solution
The design incorporates a frame with pivot connection grooves, stop grooves, and locating assemblies that allow the frame rods to be securely clamped and locked in place without requiring excessive force, enhancing operational safety by allowing the trampoline to fold into a flat position and ensuring the rods remain stable during storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the trampoline frame is made foldable to improve storage and transport, then the compactness and storage efficiency are improved, but the safety and reliability deteriorate due to strong elastic contraction forces causing frame rods to eject or clamp users
Solution Approach 1:
The patent applies preliminary action by pre-configuring pivot connection grooves and stop grooves on the frame rods before folding operation. These grooves are designed in advance to guide and control the folding movement, ensuring that the frame rods automatically engage at safe positions during the folding process, thereby preventing ejection or clamping hazards while achieving compact folded size
Solution Approach 2:
The patent introduces pivot connection grooves and stop grooves as intermediary structures that mediate between the frame rods and the folding motion. These grooves act as intermediaries to control the interaction between frame components during folding, guiding the movement and preventing direct contact that could cause ejection or clamping, thus maintaining safety while enabling foldability
2Stability of the object's composition
If force is applied to maintain the folded position of frame rods, then the stability in folded state is improved, but the ease of operation deteriorates due to requiring continuous force application
Solution Approach 1:
The patent applies preliminary anti-action by designing stop grooves that preemptively counteract the elastic contraction force attempting to eject the frame rods. The stop grooves are positioned to engage with corresponding features on adjacent frame rods, creating a mechanical stop that prevents backward movement and maintains folded position stability without requiring continuous user force application
Solution Approach 2:
The patent implements self-service through the automatic engagement mechanism where pivot connection grooves and stop grooves self-lock the frame rods in their folded position. Once the folding operation is initiated, the grooves automatically engage and maintain the folded state without requiring continuous user intervention or force application, thereby improving ease of operation while maintaining stability
3Reliability
If pivot connection grooves and stop grooves are added to control frame rod movement, then the safety and reliability are improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the pivot connection grooves and stop grooves to serve multiple functions simultaneously. These grooves not only guide the folding movement but also provide automatic locking, prevent ejection, and maintain folded position stability. By combining multiple safety functions into a single groove structure, the patent improves reliability without proportionally increasing device complexity
Solution Approach 2:
The patent merges the functions of pivot connection and position stopping into integrated groove structures. Instead of separate components for guiding and locking, the patent combines these functions into unified pivot connection grooves and stop grooves that perform both functions, thereby improving safety while minimizing the increase in device complexity

AI summary
A trampoline includes a trampoline frame including a trampoline frame ring supported by a trampoline frame. A trampoline bed is supported across the trampoline frame. The trampoline frame is foldable. Enclosure poles are oriented in a vertical orientation when the enclosure poles are in a deployed position. One or more hinge joints connect the enclosure poles to the trampoline frame. The enclosure poles are mounted to the trampoline frame ring at the hinge joints. The enclosure poles fold inward to a horizontal position when the enclosure poles fold to a folded position. The enclosure poles may overlap each other when folding to the folded position.
