Solution Overview

Problem

Current electronic devices that integrate proximity sensing, ambient light sensing, and gesture recognition functions as individual modules result in increased size and power consumption due to the need for separate processing and signal conversion.

Innovation Solution

A gesture recognition apparatus and complex optical apparatus are integrated into a single module, comprising a substrate with a light emitting device, image sensor, and processing unit, where the light emitting device emits a light beam and the image sensor receives it to generate an object image, with the processing unit recognizing the image and outputting command signals, reducing processing time and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If proximity sensing, ambient light sensing, and gesture recognition devices are assembled as individual modules, then each function can be independently implemented, but the size of the electronic device increases and power consumption increases due to separate processing and signal conversion

Engineering Contradiction:
Improvefunctional capabilityVSAvoiddevice size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent combines proximity sensing, ambient light sensing, and gesture recognition functions into a single integrated optical sensing device. The device includes a light emitting device, an image sensor, and a processing unit all disposed on the same substrate, enabling multiple functions to be performed by one unified structure rather than separate modules

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated optical sensing device is designed to perform multiple functions simultaneously: proximity sensing by detecting reflected light intensity, ambient light sensing by measuring environmental light levels, and gesture recognition by analyzing motion patterns in the captured images. This multi-functional design eliminates the need for separate dedicated devices for each function

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

2Ease of manufacture

If individual modules are used for optical sensing functions, then each module can be optimized independently, but processing time increases and power consumption increases due to separate processing units and signal conversion requirements

Engineering Contradiction:
Improvemodule optimizationVSAvoidprocessing time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The processing unit is integrated with the image sensor and light emitting device on the same substrate, enabling direct processing of sensor data without external signal conversion. This integration eliminates intermediate processing steps and reduces the time required to convert optical signals into usable information

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent eliminates the need for external intermediary processing units by incorporating the processing functionality directly into the optical sensing device. The processing unit on the substrate acts as an internal mediator that directly processes sensor data, removing the need for separate processing modules and reducing overall processing time

Inventive Principle:
Principle #24Intermediary (Mediator)
