Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trampolines have fixed elasticity, limiting the variety of exercise experiences for users.
Innovation Solution
The trampoline features adjustable ring parts connected through a T-shaped joint with a connecting rod and positioning parts, allowing the arc length between adjacent rings to be adjusted and fixed, with optional check rings to alter the trampoline's size and elasticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trampoline uses fixed elasticity design, then the structure is simple, but the exercise experience variety is limited
Solution Approach 1:
The patent applies the dynamics principle by making the trampoline ring parts adjustable rather than fixed. The ring parts can be repositioned along the frame to change the trampoline's dimensions and elasticity characteristics, allowing the same structure to adapt to different exercise needs and user preferences.
Solution Approach 2:
The patent implements parameter changes by allowing modification of the trampoline's physical parameters (ring position, arc length, elasticity) through adjustable components. Users can change the configuration parameters of the ring parts to achieve different exercise experiences from the same trampoline structure.
2Adaptability or versatility
If the trampoline ring arc length is adjustable, then the elasticity is customizable, but the joint structure becomes complex
Solution Approach 1:
The patent applies segmentation by dividing the trampoline frame into multiple adjustable ring parts connected by joints. Each ring part can be independently positioned and adjusted, allowing modular modification of the trampoline's geometry and elasticity without redesigning the entire structure.
Solution Approach 2:
The patent uses joints as intermediary components that facilitate adjustment between ring parts. These joints act as mediators that enable the connection and reconfiguration of ring parts while managing the structural complexity through standardized interface mechanisms.
3Manufacturing precision
If multiple adjustment mechanisms are added, then the elasticity control precision is improved, but the operation complexity increases
Solution Approach 1:
The patent incorporates self-service features in the adjustment mechanisms, such as self-locking joints and intuitive positioning systems that automatically maintain the desired configuration without requiring complex fastening or adjustment procedures by the user.
