Innovation Solution
A zip line system comprising a rigid track with connected segments and a trolley that includes upper and lower wheel mounts, allowing smooth movement and support for riders, with the track segments forming various shapes and configurations to accommodate different designs and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional playground equipment is used, then it is simple and familiar to children, but it is not size-appropriate for teenagers and taller children, lacking physical challenge
Solution Approach 1:
The track is divided into multiple modular track segments that can be connected in various configurations. Each segment is a standardized unit with connection features, allowing the overall structure to be scaled and adapted for different height requirements while maintaining manufacturing simplicity through standardization.
Solution Approach 2:
The trolley incorporates wheel mounts with adjustable angles and movable wheel assemblies that can adapt to different track configurations and rider weights. The upper wheel mounts can be positioned at different angles to accommodate various track shapes, providing dynamic adaptability for teenagers and taller children while maintaining a relatively simple base structure.
2Reliability
If track segments are connected with freedom of movement, then assembly is easier, but the ride becomes unstable and discontinuous
Solution Approach 1:
The track segments include pre-formed connection features such as flanges, slots, and alignment elements that are manufactured in advance. These preliminary structural elements guide the assembly process and ensure proper alignment, making field assembly easier while guaranteeing a smooth, continuous ride surface when connected.
Solution Approach 2:
Connection elements act as intermediaries between track segments, providing both mechanical attachment and precise positioning. These intermediaries include adjustable clamps, alignment pins, and connection plates that facilitate easy assembly while ensuring the segments connect with minimal gap and proper alignment for ride continuity.
3Adaptability or versatility
If the trolley has fixed wheel mounts, then the structure is simpler, but it cannot accommodate various track shapes and configurations
Solution Approach 1:
The upper wheel mounts are designed with adjustable angle mechanisms that allow the wheel assembly to be positioned at different angles relative to the track. This dynamic adjustment capability enables the same trolley to accommodate various track shapes (straight, curved, banked) without requiring multiple specialized trolley designs.
Solution Approach 2:
The trolley is designed as a universal platform that can interface with different track segment types through its adjustable wheel mounts. The same basic trolley structure can serve multiple functions across different track configurations, reducing the need for specialized components while maintaining structural simplicity through standardized base design.

Function Achieved in This Case
The zip line system provides a fun and challenging experience for teenagers and taller children by ensuring a smooth, continuous ride with minimal disengagement, accommodating various track shapes and sizes, thus enhancing playground usability.
Implementation Method 1
a trolley adapted to move along the track
Implementation Method 2
the at least one second upper wheel will engage the track flange upon rotational movement of the trolley relative to the track run

AI summary
A zip line includes a substantially rigid track supported above a ground surface by a plurality of supports, a trolley which moves along the track, and a rider support suspended from the trolley. The track is comprised of a plurality of track segments connected together such that adjacent track segments have substantially no freedom of movement relative to each other, and such that adjacent track segments present a substantially smooth, continuous, and uninterrupted surface. The track includes a run and a flange extending upwardly from the run. The trolley comprises a frame having upper wheel mounts to which first and second upper wheels are rotatably mounted. The first upper wheels are oriented such that they engage an upper surface of the track run and the second upper wheels are oriented such that they will engage the track flange upon rotational movement of the trolley relative the track run.
