Spring-Driven Bull's-Eye Feedback Mechanism for Shooting Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shooting targets lack feedback mechanisms, making it difficult for users to determine if they have hit the bull's-eye, thereby causing inconvenience and reducing the enjoyment of shooting games.
Innovation Solution
A feedback device is introduced, comprising a target body with a telescopically movable bull's-eye and a flagpole that can extend outward automatically upon the bull's-eye being struck, utilizing springs for the telescopic movements and a detachable connection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a monolithic panel structure is used for shooting targets, then the structure is simple and easy to manufacture, but no feedback is provided when the target is struck
Solution Approach 1:
The target is divided into multiple functional components: a target body, a bull's-eye with guiding columns, and a flagpole with guiding protrusions. Each component can move independently and provides specific feedback functions, resolving the contradiction between structural simplicity and feedback capability.
Solution Approach 2:
The bull's-eye and flagpole are designed to be telescopically movable rather than fixed. The bull's-eye moves in response to being struck, and the flagpole extends outward to provide visual feedback. This dynamic behavior enables feedback provision while maintaining a relatively simple overall structure.
2Ease of operation
If no items are ejected from the target, then the target structure remains simple, but users cannot quickly ascertain whether they have hit the bull's-eye
Solution Approach 1:
The system provides immediate feedback when the bull's-eye is struck. The bull's-eye retracts and then extends forward under spring action, causing the flagpole to eject outward. This mechanical feedback mechanism allows users to quickly determine if they have hit the bull's-eye without complex electronic or optical systems.
Solution Approach 2:
The target provides its own feedback automatically when struck. The spring-driven bull's-eye and flagpole mechanism operates autonomously without requiring external power sources, sensors, or complex control systems, maintaining simplicity while enabling effective feedback.
3Reliability
If a telescopically movable bull's-eye and flagpole mechanism is added, then feedback is provided upon impact, but the device complexity increases
Solution Approach 1:
The bull's-eye and flagpole are nested within the target body's installation cavity. The bull's-eye telescopes within the cavity, and the flagpole extends from the bull's-eye in a nested arrangement. This nesting approach provides feedback functionality while minimizing the overall space required and maintaining structural compactness.
Solution Approach 2:
The feedback mechanism uses simple mechanical springs rather than complex mechanical systems. The first spring drives the bull's-eye movement, and the second spring drives the flagpole extension. This substitution of complex mechanisms with simple spring-based systems reduces device complexity while maintaining reliable impact feedback.

AI summary
A feedback device which ejects items upon hitting target surface is provided, including a target body, a bull's-eye, a flagpole, a first spring, and a second spring. The target body has an installation cavity, and an installation hole is provided at the center of the front face of the target body. The bull's-eye is configured to be telescopically movable within the installation cavity and extends through the installation hole. The flagpole is also configured to be telescopically movable within the installation cavity and extends outward from the target body. The flagpole is detachably connected to the bull's-eye. The first spring is positioned within the installation seat and drives the bull's-eye to extend forward. The second spring is located within the installation cavity and drives the flagpole to extend outward. This allows players to quickly determine whether the bull's-eye has been hit, providing convenience and enhancing enjoyments of shooting games.
