Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recreational and sports shooting impact location installations face deformation issues due to repeated impacts, leading to measurement errors, which existing solutions like replacing the interactive plate or inclining it do not fully address, as they are costly or impractical.
Innovation Solution
An additional plate is attached to the interactive plate to absorb impact energy, protecting it and ensuring wave propagation, with simpler and more economical replacement, using attaching means like mechanical clamping or adhesive layers, allowing the interactive plate with transducers to remain undamaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the interactive plate is used repeatedly for impact location, then measurement precision is improved, but the plate deforms under repeated impacts causing measurement errors
Solution Approach 1:
The system is divided into two separate plates: a first interactive plate with transducers for measurement and a second plate for impact absorption. This segmentation allows the measurement plate to remain stable while the impact plate absorbs deformation from repeated shots.
Solution Approach 2:
The second plate acts as an intermediary between the projectile and the first interactive plate. It absorbs the impact energy and transfers minimal disturbance to the measurement plate, protecting it from deformation while maintaining measurement accuracy.
2Measurement precision
If the interactive plate is replaced regularly to maintain accuracy, then measurement precision is maintained, but cost increases due to precise transducer positioning requirements
Solution Approach 1:
The second plate is designed as a replaceable, impact-absorbing component that can be easily replaced when depleted. This eliminates the need to replace the expensive first interactive plate with precisely positioned transducers, reducing replacement costs and complexity.
Solution Approach 2:
By segmenting the system into a measurement plate and an impact plate, the invention isolates the wear and deformation to the impact plate only. This allows the expensive measurement plate to be retained indefinitely while the cheaper impact plate is replaced as needed.
3Duration of action of stationary object
If the interactive plate is inclined to protect against high-energy impacts, then durability is improved, but impact location accuracy deteriorates due to trajectory deviation
Solution Approach 1:
The segmentation into two plates allows the impact plate to be inclined for durability while the measurement plate remains perpendicular for accurate impact location. The inclined second plate absorbs high-energy impacts without affecting the measurement capabilities of the first plate.
4Duration of action of stationary object
If the target representation is moved to distribute impacts per unit area, then plate lifespan is extended, but ease of operation deteriorates as shooters must physically move to track the changing display position
Solution Approach 1:
The segmentation separates the impact absorption function (second plate) from the display function (first plate). This allows the target representation to remain stationary on the measurement plate while the impact-absorbing second plate can be replaced or configured to protect against impacts without requiring display movement.
