Solution Overview

Problem

Existing electronic shot evaluation systems for rapid-fire disciplines lack an effective mechanism to protect the optical display from projectile impacts while allowing shooters to receive clear shot release indicators, leading to potential damage and loss of evaluation data.

Innovation Solution

A firing frame with a transparent or semi-transparent body that protects the optical display by positioning it behind the frame, allowing optical signals to be emitted through the frame body, which can absorb projectile impacts and provide a bulletproof, flat surface for uncontrolled ricochet prevention, utilizing materials like glass ceramic and composite panes for enhanced durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the optical display is placed in front of the firing frame for clear visibility, then the shot release indicator is more visible to the shooter, but the display becomes vulnerable to projectile impacts and damage

Engineering Contradiction:
Improvevisibility of shot release indicatorVSAvoidprotection from projectile impacts
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent inverts the conventional arrangement by placing the optical display behind the firing frame rather than in front, allowing the frame to serve as a protective barrier while the display remains visible through the transparent material

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The transparent or semi-transparent firing frame acts as an intermediary element between the shooter and the optical display, providing physical protection while allowing optical signals to pass through

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a transparent or semi-transparent frame body is used to protect the optical display, then the display is protected from projectiles, but the frame material must balance transparency with impact resistance

Engineering Contradiction:
Improveprotection from projectile impactsVSAvoidmaterial selection and fabrication
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs composite materials that combine transparent or semi-transparent properties with high impact resistance, such as transparent plastics, glass ceramics, or laminated structures, to simultaneously achieve protection and optical signal transmission

Inventive Principle:
Principle #40Composite materials

3Reliability

If the frame body completely covers the optical display for maximum protection, then the display is fully protected, but the optical signals may be attenuated or blocked

Engineering Contradiction:
Improveprotection from projectile impactsVSAvoidstrength of optical signals
Core Design Contradiction:
ReliabilityVSIllumination intensity

Solution Approach 1:

The patent applies local quality by using transparent or semi-transparent materials in specific areas of the frame body where optical signals need to pass through, while maintaining protective coverage, thus balancing protection with signal transmission

Inventive Principle:
Principle #3Local quality
