Central-Opening Game Net and Centrifugal-Braking Shuttlecock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing racket sports games require large areas and boundary lines due to the distance shuttlecocks can travel, limiting play in confined spaces.
Innovation Solution
A game net with a central opening and a shuttlecock design that self-limits speed and flight distance through centrifugal forces on its tail feathers, allowing play without boundary lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional shuttlecocks are used that can fly long distances, then the shuttlecock can travel far when hit hard, but the game requires large areas and boundary lines which cannot be played in confined spaces
Solution Approach 1:
The shuttlecock's flight characteristics are modified by changing physical parameters of its structure - specifically the flexibility and configuration of tail feathers. When struck, the feathers bend outwardly due to centrifugal forces, increasing air resistance and limiting flight distance. This parameter change allows the shuttlecock to travel shorter distances while maintaining playability, enabling games in confined spaces without boundary lines
Solution Approach 2:
The centrifugal forces that normally cause the shuttlecock feathers to bend outward and increase drag (which would normally be seen as resistance slowing the shuttlecock) are converted into a beneficial braking mechanism. The harder the shuttlecock is struck, the greater the centrifugal force and feather bending, creating a self-regulating system that limits maximum flight distance and enables play in small areas
2Adaptability or versatility
If a net with a central opening is used to enable play in small spaces, then the game can be played without boundary lines, but players must direct the shuttlecock with higher precision through the window
Solution Approach 1:
The net is segmented to create a distinct central opening or window through which the shuttlecock must pass. This segmentation of the net structure into netting material and an opening creates a targeted passage that defines the valid playing area, allowing players to hit the shuttlecock through a specific zone rather than requiring large boundary definitions
3Area of stationary object
If the shuttlecock is designed to self-limit speed through centrifugal forces on tail feathers, then the shuttlecock can be used in smaller spaces, but the harder it is struck the greater the braking action from feather bending
Solution Approach 1:
The shuttlecock is designed to regulate its own flight characteristics without external intervention. The tail feathers are configured to automatically bend outwardly under centrifugal force when the shuttlecock is struck, creating a self-regulating braking mechanism. The harder the strike, the greater the centrifugal force and feather bending, and thus the greater the braking action, allowing the shuttlecock to self-limit its flight distance and speed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables play in small spaces with precise aiming and fair gameplay, eliminating the need for court boundaries.
Implementation Method 1
The shuttlecock construction is such that when it is struck, the shuttlecock spins about its axis and induces centrifugal forces on its tail feathers. The centrifugal forces acting on the tail feathers cause the tips of the feathers to bend outwardly inducing a braking action

AI summary
A game system having a net and a shuttlecock for playing a game involving hitting the shuttlecock back-and-forth between players located on opposite sides of the net. The net is supported above a ground surface and has an opening formed therethrough to provide passage of the shuttlecock through the net when hit by one or more players located on opposite sides of the net. The shuttlecock has a plurality of flexible feather fins that are specifically configured and arranged to provide airspeed braking of the shuttlecock when in flight to control the speed and the distance that the shuttlecock may be hit.
