Solution Overview

Problem

Existing gunsights require frequent battery replacement due to small button battery capacity, leading to inconvenience and time wastage, especially in strong light environments where aiming accuracy is critical.

Innovation Solution

A chargeable gunsight bracket with a built-in power supply circuit board and charging interface allows for external power charging without disassembly, using a micro USB, Type-C, 30-PIN, or lightning interface, and includes waterproofing features to prevent moisture ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a button battery is used in the gunsight, then the device can be powered, but the battery capacity is small and needs frequent replacement

Engineering Contradiction:
Improvebattery usage durationVSAvoidbattery replacement convenience
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The patent extracts the battery replacement operation from the gunsight housing by providing a dedicated battery compartment that can be opened independently. This allows users to replace batteries without disassembling the main housing, significantly improving operational convenience while maintaining adequate battery capacity for extended use

Inventive Principle:
Principle #2Taking out (Extraction)

2Duration of action of moving object

If the battery capacity is increased to reduce replacement frequency, then the duration of action is improved, but the device size and complexity increase

Engineering Contradiction:
Improvebattery usage durationVSAvoidpower supply system complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The power supply system is segmented into a rechargeable battery module with integrated charging circuit and a separate solar charging module. This segmentation allows the main device to use a compact rechargeable battery for immediate power needs, while the solar module provides external charging capability, thereby extending effective duration without increasing the core device complexity

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If a charging interface is added to the gunsight bracket, then external charging is enabled, but the device structure becomes more complex

Engineering Contradiction:
Improvecharging capabilityVSAvoidbracket structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging interface is designed as a multi-functional component that serves both as a charging port and a structural element of the bracket assembly. By integrating the charging function into an existing structural interface, the patent enables external charging capability without significantly increasing overall device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
