Rotating Target Game With Lattice Sidewalls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectile target games face challenges in cost-effective design and scoring accuracy, particularly due to the material costs of solid target structures and the potential for projectiles to fall out of rotatable targets, affecting scoring consistency.
Innovation Solution
The design incorporates a lattice-type structure for the target sidewalls, which reduces material costs and allows for visible identification of projectiles, combined with a support frame that includes collapsible and rotatable elements to manage projectile placement and scoring, using markers for point indication and varying target sizes for different point values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid target structures are used, then structural strength and projectile containment are improved, but material costs and manufacturing complexity increase
Solution Approach 1:
The target structure is divided into modular components including a target body, support frame with legs, and base structure. Each component can be manufactured separately and assembled, reducing overall manufacturing complexity while maintaining structural integrity through standardized connection points and modular design
Solution Approach 2:
The support frame incorporates localized reinforcement at critical stress points such as joint connections between legs, target body, and base. This allows the structure to achieve necessary strength at specific locations without requiring solid construction throughout the entire frame, reducing material costs and manufacturing complexity
2Adaptability or versatility
If rotatable targets are used, then gameplay excitement and adaptability are improved, but scoring consistency and reliability deteriorate due to projectiles falling out
Solution Approach 1:
The target structure incorporates rotatable elements that can be rotated to different orientations during gameplay. The support frame includes rotation joints that allow the target body to be positioned at various angles while maintaining stable projectile containment through gravity-assisted retention mechanisms
Solution Approach 2:
The target design includes preliminary containment features such as angled bottoms and retention edges that prevent projectiles from falling out during rotation. These features are built into the target structure before rotation occurs, ensuring projectiles remain contained regardless of the target's rotational position
3Ease of manufacture
If lattice-type structure is used for target sidewalls, then material costs and visibility are improved, but structural strength may be reduced
Solution Approach 1:
The target sidewalls utilize a lattice-type porous structure that reduces material usage and cost while maintaining sufficient structural strength. The lattice geometry is designed to provide structural rigidity through its framework configuration, and the porous nature allows for projectile visibility and air flow to reduce wind resistance
Solution Approach 2:
The lattice structure is constructed using composite material arrangements where rigid framework elements provide structural strength while lighter infill materials or open spaces reduce overall weight and material cost. This composite approach maintains sidewall strength while achieving cost reduction and visibility benefits

A target projectile tossing game including a frame, a horizontal support connected to the frame, and a target coupled to the horizontal support. The target may be sized to receive the projectile therein and may further be configured to rotate relative to the frame based on force from the tossed projectile.
