Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trampoline support leg designs require a large force to separate the support leg from the trampoline frame for storage, leading to severe deformation of springs and increased elastic fatigue, making repeated bending difficult and user experience poor.
Innovation Solution
A trampoline support frame with pivotally connected support legs featuring a spring in an operating sleeve, where the sleeve's state change allows easy bending of the legs without severe spring deformation, using a bridging member and post foot to manage the spring's compression and return.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional spring structure is used where the spring is arranged between the trampoline frame and the bottom of the support leg space, then the support leg can be separated for storage, but a very large force is required to separate the support leg from the frame, causing severe spring deformation and elastic fatigue
Solution Approach 1:
The patent introduces an operating sleeve as an intermediary component between the user's hand and the spring mechanism. The sleeve transmits and amplifies the user's input force through mechanical advantage, allowing the support leg to be separated from the frame without requiring the user to directly apply very large force that would cause severe spring deformation and elastic fatigue.
Solution Approach 2:
The patent makes the support leg assembly dynamic by allowing the operating sleeve to move along the support leg between extended and retracted positions. This dynamic mechanism enables easy transition between the stored and deployed states of the support leg, resolving the contradiction between ease of operation and spring reliability.
2Ease of operation
If a conventional spring structure is used where the spring is arranged between the trampoline frame and the bottom of the support leg space, then the support leg can be separated for storage, but the user must apply a very large force that deforms the spring severely, making repeated bending difficult
Solution Approach 1:
The operating sleeve acts as a mechanical intermediary that reduces the force required from the user by utilizing spring pre-compression and mechanical leverage. This allows repeated bending operations without severe spring deformation, extending the duration of action and repeated bending capability.
Solution Approach 2:
The spring is pre-compressed within the operating sleeve to a controlled degree during normal operation. This beforehand cushioning of elastic energy allows the mechanism to absorb and manage the forces involved in separation and attachment, preventing severe deformation during repeated bending operations.
3Device complexity
If the spring is arranged in the support leg with ends on the frame and inside the support leg space, then the structure is simple, but the user experience is poor because the user cannot easily bend the support leg for storage
Solution Approach 1:
The patent segments the support leg assembly into distinct functional components: the support leg itself, the operating sleeve, and the spring mechanism. This segmentation allows the spring to remain relatively simple in arrangement while the operating sleeve provides the user interface for easy operation, resolving the contradiction between structural simplicity and ease of operation.
Solution Approach 2:
The operating sleeve serves as a mediator between the user and the simple spring arrangement. It translates user input into controlled spring compression and release, enabling easy support leg bending for storage while maintaining the simplicity of the underlying spring structure.

AI summary
A trampoline support frame (100) with bendable support legs comprises a frame (10) and a plurality of support legs (20). The frame (10) comprises a plurality of support tubes (11), an in-frame space (13) and a plurality of connection posts (12). Each of the support legs (20) comprises a bridging member (21), an operating sleeve (22) sleeved on the bridging member (21), a spring (23) and a post foot (24) arranged in the operating sleeve (22), wherein the spring (23) is arranged in the operating sleeve (22). When each operating sleeve (22) is stressed to compress the corresponding spring (23) to be separated from the connection post (12), each of the support legs (20) moves by a pivoting stroke (80) which allows the support leg to be folded toward the in-frame space (13). Compared with the conventional trampoline support frame, the present invention has the following characteristic: the operating sleeve (22) is matched with the spring (23), and the spring (23) is not subjected to severe deformation during the implementation, so that the spring (23) is less prone to elastic fatigue. Further, the number of times the support legs (20) are stored is increased, and the consumer has the best experience in use.
