Stackable Archery Target With Replaceable Cube Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archery targets with replaceable cores are expensive and require additional targets for stray arrows, and existing targets are bulky and costly due to their single-use nature and limited usability.
Innovation Solution
A stackable archery target system with multiple replaceable cube cores and a base that houses these cores, allowing for multiple target surfaces and easy stacking, along with optional features like Velcro attachments and grooves for securing multiple targets, enabling extended use and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If high density materials are used to create smaller targets, then portability and ease of handling are improved, but the targets become single-use and costly
Solution Approach 1:
The target is divided into two functional segments: a permanent base structure and replaceable cube cores. The base provides the structural framework while the cube cores contain the high-density stopping material. This segmentation allows the expensive high-density material to be concentrated only where needed (in the cube cores) rather than throughout the entire target structure, reducing overall weight while maintaining stopping power and enabling core replacement to extend target lifespan.
Solution Approach 2:
The cube cores are designed to be replaceable rather than permanent. When the cube cores become worn or depleted from arrow impacts, they can be removed and replaced with fresh cores, thereby recovering the value of the permanent base structure and extending the overall lifespan of the target system without requiring replacement of the entire target.
2Shape
If 3D targets with realistic animal shapes are used, then visual appeal is improved, but additional targets are needed for stray arrows increasing cost
Solution Approach 1:
The cube core design provides multi-functionality: each cube can be positioned to present different target surfaces (front, back, sides) and can serve multiple shooting scenarios. The modular cube system allows a single target assembly to function as multiple targets by rotating or repositioning cubes, eliminating the need for additional backup targets for stray arrows while maintaining visual appeal through various cube configurations.
3Strength
If traditional straw targets are used, then stopping power is improved, but the targets are bulky and difficult to transport
Solution Approach 1:
Instead of distributing stopping power uniformly throughout a large volume of straw material, the invention concentrates high-density stopping material locally within the cube cores. The base structure provides minimal structural support while the cube cores provide concentrated stopping power where arrows actually impact. This local quality approach achieves the same stopping power with significantly reduced overall weight and volume compared to traditional straw targets.
4Weight of moving object
If cube cores are made with expandable foam, then portability is improved, but the cores may shift or move under impact
Solution Approach 1:
The cube cores are nested within recesses or cavities in the base structure, creating a nested configuration where the cube cores are physically contained within the base. This nesting arrangement prevents the lightweight expandable foam cores from shifting or moving under arrow impact while maintaining their low weight and portability advantages. The base structure acts as a container that stabilizes the cube cores without adding significant weight.

AI summary
The Stackable Archery Target Having Replaceable Cube Cores includes a plurality of replaceable cube cores, one or more core receivers. and a base. The base is formed with one or more core receivers, which receive one of more replaceable cube core. The replaceable cube core provides a visual target display for archers to aim and shoot The base ensures that the cube cores are firmly held within the confines of the core receiver to prevent the replaceable cube core from shifting or moving under impact from the arrows. The replaceable cube core is formed as a cube having three (3) useable target surfaces. Each target surface provides a consistent penetration depth on each surface for predictable results, regardless of the face that is used for the target surface. When one face has been sufficiently used, the user rotates the cube to show a fresh target display.
