Solution Overview
Problem
Rotating playground devices pose safety concerns due to unrestricted rotation and lack of enclosures, which can lead to injuries from falls or being thrown off, especially for small children, and existing solutions do not adequately address the need for safe and engaging play.
Innovation Solution
A rotating playground device with a permanently mounted frame that includes a progressive braking system and fall protection mechanisms, such as netting, to limit speed and prevent users from falling off, while allowing access to internal seating areas for safe user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rotating playground devices allow unrestricted rotation, then users can freely spin and play, but safety risks increase due to potential falls and high speeds
Solution Approach 1:
The braking system applies preliminary counter-action to the rotation before dangerous speeds are reached. The brake assembly continuously monitors and applies braking force to prevent the rotating platform from reaching hazardous rotational speeds, thereby preventing falls and injuries before they can occur.
Solution Approach 2:
The braking system acts as an intermediary between the user's rotational input and the platform's motion. It mediates the rotation by allowing controlled movement while automatically applying braking force when speed thresholds are exceeded, preventing direct transmission of dangerous rotational forces to the users.
2Object-affected harmful factors
If a braking system is added to limit rotation speed, then safety is improved, but device complexity increases
Solution Approach 1:
The braking system is designed to be self-regulating and automatic, requiring no external control or complex electronic systems. The brake assembly automatically engages and disengages based on the rotational speed of the platform, using the platform's own motion to trigger the braking action, thereby simplifying the overall control architecture.
Solution Approach 2:
The patent replaces complex electronic speed control systems with a purely mechanical braking mechanism. The brake assembly uses mechanical linkages and friction-based braking surfaces that automatically respond to rotational speed through mechanical means, eliminating the need for sensors, motors, or electronic control circuits.
3Object-affected harmful factors
If fall protection mechanisms like netting are added, then user safety is enhanced, but manufacturing complexity and cost increase
Solution Approach 1:
The fall protection system uses flexible netting made from thin, lightweight materials that can be easily formed and installed. The netting consists of flexible cords or ropes woven into a mesh pattern that can conform to the platform's shape, requiring minimal structural support and simplifying both manufacturing and installation processes.
Solution Approach 2:
The fall protection netting is divided into modular sections or panels that can be independently manufactured and then assembled together. This segmentation allows for easier production, quality control, and installation, as well as replacement of individual sections if needed, reducing overall manufacturing complexity.
