Modular Shoot House Walls With Vertical-Adjustable Ballistic Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoot houses are cumbersome to disassemble and move due to their massive, thick walls, and they do not allow for easy adjustment to different terrains, while also failing to prevent bullet ricochets effectively.
Innovation Solution
The shoot house walls are constructed of ballistic penetration-resistant materials with male and female connective structures that allow for relative vertical motion and quick assembly/disassembly, using arrow-head and arrow-receptacle shapes for connection, enabling modular and adjustable construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If massive thick walls are used to withstand bullet impact and prevent ricochets, then protection reliability is improved, but ease of assembly and disassembly deteriorates
Solution Approach 1:
The wall system is divided into modular panels with standardized edge connective structures. Each panel can be independently assembled and disassembled through interlocking mechanisms (arrow-head and arrow-receptacle shapes), allowing the protective structure to be rebuilt efficiently after use without compromising ballistic resistance.
2Stability of the object's composition
If fixed structural walls are used to ensure stability, then structural stability is improved, but adaptability to different terrains deteriorates
Solution Approach 1:
The wall panels incorporate adjustable height mechanisms and modular configurations that allow the structure to adapt to varying terrain conditions. The panels can be assembled at different heights and arrangements while maintaining structural integrity through the standardized connective structures, enabling deployment on slopes, flat ground, or uneven surfaces.
3Reliability
If heavy materials are used to prevent bullet ricochets, then protection effectiveness is improved, but ease of movement deteriorates
Solution Approach 1:
The heavy protective material is segmented into manageable panels with integrated connective structures. This segmentation allows the panels to be moved and repositioned relatively easily despite the heavy material, as each panel can be handled independently and quickly connected to form the complete protective wall structure.
Solution Approach 2:
The connective structures are designed with exaggerated geometric features (large arrow-head and arrow-receptacle shapes) that provide excessive mechanical advantage and ease of connection, compensating for the weight of the protective material and enabling quick assembly and disassembly even with heavy panels.

AI summary
A training system includes shoot house walls (10) connected to each other, each of the walls (10) being constructed of a ballistic penetration-resistant material. The wall (10) includes front and back surfaces (12, 14) extending from first and second edge connective structures (16, 18). The first and second edge connective structures (16, 18) include an upright projection (20) received in a crevice (22) that allows for relative vertical motion between adjoining walls (10).
