Bifacial Target With Hinged Arms For Self-Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm targets are often destroyed during use or require manual resetting, which is inconvenient and inefficient.
Innovation Solution
The development of self-repositioning targets with four bifacial, shaped target areas and planar extension arms that meet at a common center, allowing the target to flip and reorient after impact, eliminating the need for manual resetting and enabling repeated use without destruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional firearm targets are used, then they are simple in structure and easy to manufacture, but they are destroyed during use or require manual resetting
Solution Approach 1:
The target is divided into multiple planar arms (at least three arms) that are hinged at a common center point, allowing each arm to independently rotate and reposition after impact. This segmentation enables the target to withstand multiple shots by redistributing impact forces across different arms rather than being destroyed by a single impact.
Solution Approach 2:
The target incorporates dynamic repositioning capability where arms can rotate between different positions (e.g., from initial position to repositioned position) after being struck. This dynamic behavior allows the target to automatically reset itself without manual intervention, transforming from a static structure that gets destroyed to a dynamic structure that adapts and continues functioning.
2Productivity
If targets that require manual resetting are used, then they can be reused, but they require time-consuming manual repositioning
Solution Approach 1:
The target performs its own resetting function automatically through the hinged arm mechanism. When an arm is struck, it naturally rotates to a new position due to the impact force and gravity, presenting a fresh target face without requiring any manual intervention. This self-service capability eliminates the time loss associated with manual resetting and significantly improves productivity.
3Strength
If single-sided targets are used, then they have simpler design, but they cannot withstand multiple impacts from different angles
Solution Approach 1:
The target employs asymmetric arm configurations where each arm can be oriented at different angles relative to the center (e.g., 0°, 120°, 240° for three arms). This asymmetric arrangement allows the target to present target faces in multiple directions, enabling it to withstand impacts from various angles while maintaining structural integrity through the hinged connection at the center.
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
The targets can withstand multiple impacts, maintain structural integrity, and allow for continuous use without manual repositioning, offering enhanced durability and ease of use, with the ability to adapt to various firearm calibers and target sizes.
Implementation Method 1
The firearm is fired to impact the front face, the impact causing the target to flip into a new position
Implementation Method 2
The two target portions are welded together along the adjoining slits

AI summary
Targets including bifacial target areas adjoining four planar extension arms that meet at a center and are set at angles of 109.5 degrees between adjacent arms. A method including providing a pair of symmetrical target portions each having two bifacial target areas adjoining extension arms that meet along a centerline. Slits are provided at centerline apexes, and the slits the two portions are merged. The two target portions are welded together along the merged slits. A method including positioning a target on a surface, with one extension arm projecting upward. A firearm is aimed at a face of the bifacial target area adjoined to the upwardly projecting arm. The firearm is fired to impact the face, the impact causing the target to flip into a new position The firearm is then aimed at a face of the bifacial target area adjoined to the new upwardly projecting extension arm.
