Solution Overview

Problem

People often feel uncomfortable and intimidated when they know they are being recorded by cameras, leading to a desire for clear indication of recording status to alleviate these concerns.

Innovation Solution

A computer-implemented method and system that determine the current recording status of a camera and provide a human-perceptible recording status indication in the vicinity of the camera, using existing or new hardware such as LEDs, speakers, or displays, to inform individuals whether they are being recorded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a camera operates without indication, then recording functionality is maintained, but people feel uncomfortable and intimidated

Engineering Contradiction:
Improvepsychological discomfortVSAvoidrecording status visibility
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The patent employs color-changing indicators (such as LEDs displaying different colors like green for recording, yellow for standby, red for error) to communicate the camera's operational status. This visual color-coding system provides immediate, intuitive information about recording state, thereby reducing psychological discomfort while maintaining functional operation.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces an intermediary indicator device that mediates between the camera's internal recording state and external human perception. This indicator acts as a communication bridge, translating the camera's operational status into human-perceptible signals (visual, auditory, or haptic), thus resolving the information asymmetry that causes discomfort.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a recording status indication is provided, then comfort and awareness of individuals is enhanced, but device complexity increases

Engineering Contradiction:
Improvepsychological discomfortVSAvoidhardware components
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent designs the indicator system to serve multiple functions: it not only displays recording status but can also indicate battery level, storage capacity, and operational errors. By making the indicator multi-functional, the patent reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while providing comprehensive information.

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

Solution Approach 2:

The patent combines the recording status indication functionality with existing camera hardware components, such as integrating LEDs into the camera body structure or using the camera's display screen for status indication. This merging approach avoids adding entirely new separate components, thus minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If multiple indication methods are used, then recording status visibility is improved, but energy consumption increases

Engineering Contradiction:
Improverecording status visibilityVSAvoidpower consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic or intermittent indication methods, such as flashing LEDs or periodic status updates on the display, rather than continuous high-energy output. The system can also use periodic audits of recording status and only activate indication when status changes occur, thereby maintaining visibility while significantly reducing overall energy consumption compared to continuous indication.

Inventive Principle:
Principle #19Periodic action
