Solution Overview

Problem

Conventional multi-sensor imaging apparatuses experience flicker issues due to the activation and deactivation of multiple illuminator sources, causing irritating and potentially harmful light pulses perceivable by human observers, and existing solutions either require expensive specialized sensors or waste illumination energy.

Innovation Solution

Implementing a broadest illuminator source to determine and activate the chosen image sensor for image processing, minimizing flicker by reducing the number of illuminator source activations and utilizing a single, brighter source for efficient illumination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple illuminator sources are activated and deactivated during sensor cycling, then image processing operations can be performed with different sensors, but flicker is produced that is perceivable and irritating to human observers

Engineering Contradiction:
Improvesensor selection flexibilityVSAvoidflicker perception
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent merges multiple illuminator sources into a single broadest illuminator source that can illuminate the entire field of view. This consolidation eliminates the flicker caused by cycling multiple illuminators on and off, while still allowing the system to cycle between multiple image sensors for processing different regions of interest. The single illuminator provides continuous illumination, preventing perceivable flicker while maintaining sensor cycling capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The broadest illuminator source serves multiple functions: it illuminates the entire field of view for any sensor, replaces the need for multiple specialized illuminators, and provides continuous illumination to prevent flicker. This universal illuminator can support any combination of sensors and any region of interest, eliminating the need for sensor-specific illuminator activation.

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

2Manufacturing precision

If multiple illuminator sources are used for different sensors, then each sensor can be optimized for its field of view, but illumination energy is wasted through repeated activation and deactivation

Engineering Contradiction:
Improvesensor optimizationVSAvoidillumination energy waste
Core Design Contradiction:
Manufacturing precisionVSLoss of energy

Solution Approach 1:

The patent combines multiple sensor-optimized illuminator sources into a single broadest illuminator source. Instead of activating and deactivating multiple illuminators, the system uses one continuous illuminator that covers the entire field of view. This eliminates the energy waste associated with repeated activation and deactivation cycles while still allowing each sensor to be optimized for its specific imaging parameters.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The broadest illuminator source provides continuous illumination throughout the field of view, eliminating the intermittent activation and deactivation of multiple illuminators. This continuous useful action maintains constant lighting levels, preventing flicker and reducing energy waste from repeated on/off cycles, while still enabling sensor cycling for optimized processing.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If conventional cycling methods are used to select image sensors, then the chosen sensor can be determined for image processing, but the activation and deactivation of illuminator sources produces light pulses at frequencies perceivable by humans

Engineering Contradiction:
Improvesensor selection efficiencyVSAvoidperceivable light pulses
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent merges multiple illuminator sources into a single continuous-brightness broadest illuminator. This allows the system to maintain constant illumination while cycling through different image sensors for processing. The continuous illumination from the single illuminator prevents perceivable light pulses and flicker, while the sensor cycling continues uninterrupted for efficient image processing operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The broadest illuminator provides continuous illumination without interruption during sensor cycling operations. This continuity eliminates the perceivable light pulses that occur when multiple illuminators are activated and deactivated in sequence. The system maintains constant useful illumination while efficiently cycling through sensors to determine the best candidate for image processing.

Inventive Principle:
Principle #20Continuity of useful action
