Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional trampoline structure is used, then it provides elastic bouncing function, but the elastic plate ends experience turning angles and horizontal distance changes during bending, limiting fluctuating amplitude and generating friction noise
Solution Approach 1:
The support structure is segmented into multiple independent elastic support units distributed around the elastic plate perimeter. Each unit independently supports the plate at discrete points, allowing the plate to bend and fluctuate freely without constrained end points, thereby eliminating friction noise and increasing fluctuating amplitude.
Solution Approach 2:
The support mechanism transitions from constraining the elastic plate in two dimensions (preventing end-point displacement and rotation) to supporting it in three dimensions through vertically-oriented elastic support units. This allows horizontal freedom of movement while providing vertical support, enabling larger fluctuating amplitudes without friction noise.
2Stability of the object's composition
If a spring-supported rigid plate is used, then the structure can stand firm, but the linear characteristics of compression springs limit the sports experience and elastic performance
Solution Approach 1:
The elastic support units are designed with adjustable parameters including spring stiffness coefficients, mounting positions, and structural configurations. This allows the system to adapt to different user weights, bouncing intensities, and spatial requirements, providing versatile elastic performance while maintaining structural stability through optimized parameter combinations.
3Use of energy by moving object
If an elastically bendable semi-rigid plate is used, then some elastic function is provided, but the supporting problem of plate end turning angles and plate end distance shortening cannot be completely solved
Solution Approach 1:
The system merges the elastic deformation capability of the flexible plate with the stable support function of multiple elastic support units. The plate provides energy storage through bending while the distributed support units maintain positional stability and prevent excessive turning angles, achieving both energy storage and support reliability simultaneously.
4Quantity of substance
If a jogging platform with four-sided tension springs is used, then the structure can be supported, but the plywood mainly relies on tension springs to store energy without effective bending, limiting elastic effects
Solution Approach 1:
The system uses a flexible elastic plate instead of rigid plywood, allowing the plate itself to bend and store energy elastically. This eliminates the need for complex tension spring systems while achieving superior energy storage capacity through the plate's inherent flexibility and the supporting elastic units.

AI summary
A trampoline (100) and an elastic system. The trampoline (100) comprises: an elastic member (1) having a first end (11) and a second end (12), wherein the portion of the elastic member (1) between the first end (11) and the second end (12) is a curved energy storage body; and an elastic support (2) comprising vertical support units (21) and a horizontal support unit (22), wherein two sets of vertical support units (21) are arranged on the horizontal support unit (22) in a spaced manner, and the two sets of vertical support units (21) are respectively connected to the first end (11) and the second end (12) of the elastic member (1) by means of connecting units for bilateral supporting and pre-tensioning the elastic member (1). In addition, when the elastic member (1) is bent and deformed, at least one of the vertical support units (21) and the horizontal support unit (22) can be driven to elastically bend and deform, such that a symmetrical elastic restoring force is applied to the first end (11) and the second end (12) of the elastic member (1) to limit a change in the horizontal distance between the first end (11) and the second end (12) during the bending and deformation of the elastic member (1). The trampoline (100) not only improves the elastic performance of the elastic member (1), but also solves the problems that the amplitude of rise and fall of the elastic member (1) is limited and friction noise may easily be generated due to angular rotation at the two supported ends of the elastic member (1) and a change in the horizontal distance between the two supported ends of the elastic member (1) caused by the bending of the elastic member (1).
