Multi-Target Clamping Assembly for Rapid Target Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing target clamps are limited to securing only a specific type of stationary infantry target, restricting users to a single type of target for live action training.
Innovation Solution
A target clamp assembly that securely supports various types of targets, including two-dimensional and three-dimensional targets, using a target holder with adjustable arms and clamps that engage different features such as apertures and slots, allowing quick and tool-free target changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple pinching action with a screw is used to clamp the target, then the clamping operation is simple, but only a specific stationary infantry target can be secured
Solution Approach 1:
The target clamp assembly is designed with multiple clamping mechanisms including a first clamp for DOD-style targets with mounting holes, a second clamp for FIG. 11 style targets with slots, and a third clamp for E-targets with apertures. This multi-functional design allows a single device to securely hold various types of targets while maintaining simple operation through consistent hand-tightening of knobs.
Solution Approach 2:
The clamp assembly is divided into separate, independent clamping mechanisms (first clamp, second clamp, third clamp) each designed for specific target types. This segmentation allows each clamp to be optimized for its particular target while the overall assembly provides versatility across multiple target formats.
2Reliability
If mounting holes and hooks are used to hold the target in place, then the target can be secured, but a tool is required to snap the target onto the hooks
Solution Approach 1:
The clamp assembly incorporates self-contained C-clamp mechanisms with integrated knobs that can be manually tightened by hand to securely fasten targets. The first clamp engages mounting holes with a pin and secures the target through hand-tightening of the knob, eliminating the need for external tools while maintaining reliable securing.
3Reliability
If four large thumb screws are used to clamp the target at each slot, then the FIG. 11 style target is held securely, but the operation becomes complex
Solution Approach 1:
The second clamp combines multiple securing functions into a single mechanism that engages both slots of the FIG. 11 style target simultaneously. Instead of using four separate thumb screws, one clamp with a single knob provides secure holding while simplifying the operation to one tightening action.
4Device complexity
If a single clamp design is used for all targets, then the device complexity is reduced, but the adaptability to different target types is limited
Solution Approach 1:
The clamp assembly integrates three different clamping mechanisms (first clamp with pin for mounting holes, second clamp for slots, third clamp with protrusions for apertures) into one unified device. Each clamp maintains a relatively simple design while the combination provides universal adaptability to secure DOD-style targets, FIG. 11 style targets, and E-targets.

AI summary
A target holder assembly for interchangeably supporting a two-dimensional target and a three-dimensional target includes an enclosure and a target holder frame connected to the enclosure, the target holder frame including a cross arm member connected between two target arms. The cross arm has a base length with clamping members extending from both ends of the base length to engage three dimensional targets. The cross arm also has receiving grooves proximate the junction of the clamping members and the base length positioned to engage the two-dimensional targets. A front protrusion is positioned along the base length to engage either the two-dimensional target or the three-dimensional target. The holder assembly further includes a clamping apparatus connected to the base length to engage either the two-dimensional target or the three-dimensional target.
