Solution Overview

Problem

Existing image capturing systems face challenges in balancing imaging sensitivity and light emission when prioritizing picture quality and continuous shooting, leading to potential increased shooting intervals due to charging and heat dissipation issues.

Innovation Solution

An image capturing system with a first mode for automatic light emission and imaging sensitivity setting, and a second mode with higher sensitivity, along with wireless communication options, where the selection of modes is controlled to prevent high imaging sensitivity when prioritizing image quality, allowing for optimized shooting conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If imaging sensitivity is increased to improve picture quality, then image quality is improved, but shooting interval increases due to charging and heat dissipation requirements

Engineering Contradiction:
Improveimage qualityVSAvoidshooting interval
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system dynamically adjusts imaging sensitivity based on the selected mode. In the first mode, standard automatic sensitivity adjustment is applied. In the second mode, higher imaging sensitivity is automatically set to enable continuous shooting without excessive charging intervals, while the system adaptively manages light emission amounts to balance performance and heat dissipation requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the imaging sensitivity parameter between two distinct modes. The first mode uses standard sensitivity settings for quality-focused shooting, while the second mode employs higher sensitivity settings optimized for continuous shooting scenarios, allowing the system to adapt to different operational requirements without manual intervention.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If imaging sensitivity is always set to be low to reduce heat dissipation needs, then shooting continuity is improved, but picture quality deteriorates when high sensitivity is needed

Engineering Contradiction:
Improveshooting continuityVSAvoidpicture quality
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system provides dynamic sensitivity adjustment through two selectable modes. The first mode maintains lower sensitivity for quality-focused individual shots, while the second mode automatically increases sensitivity for continuous shooting scenarios, allowing optimal performance characteristics to be selected based on shooting requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention implements periodic mode switching capability where the system can alternate between first mode (standard sensitivity) and second mode (high sensitivity) operations. This allows the system to cycle through different sensitivity levels appropriate for different shooting phases, balancing quality and continuity needs over time.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If wireless communication with other illumination apparatus is enabled, then coordination and control capability is improved, but system complexity and communication interference increase

Engineering Contradiction:
Improvecoordination capabilityVSAvoidcommunication system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication unit is designed with multi-functionality, capable of operating in both wireless communication mode and non-communication mode. This universal design allows the same hardware to serve different purposes: enabling coordinated control when wireless communication is needed, while maintaining simplicity when standalone operation is sufficient, thus adapting to various operational contexts.

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