Solution Overview

Problem

Wearable electronic devices, such as smart watches, face challenges in integrating cameras without compromising user mobility due to space constraints from displays and other components, leading to interference with user activities and suboptimal camera quality.

Innovation Solution

A digital camera assembly is integrated within a housing of the wearable device, positioned in a protrusion that extends over a band slot, minimizing interference with other components and allowing for a clear viewing angle, with specifications including 720p to 4K video resolution and 0.9 MP to 12 MP image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a camera is integrated into a wearable electronic device, then image capture capability is improved, but the device interferes with user's range of motion during activity

Engineering Contradiction:
Improveimage capture capabilityVSAvoiduser's range of motion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The camera assembly is positioned in a protrusion that extends from the housing in a direction substantially perpendicular to the display surface. This spatial repositioning moves the camera from the flat device plane into a third dimension, allowing it to capture images without requiring the main device body to interfere with the user's wrist movement or range of motion during physical activities.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If a large display is included in a wearable device, then graphical information display is improved, but space for other components is reduced

Engineering Contradiction:
Improvedisplay areaVSAvoidspace for camera components
Core Design Contradiction:
Area of stationary objectVSVolume of stationary object

Solution Approach 1:

The protrusion structure creates additional spatial volume by extending perpendicular to the display plane. This allows the camera assembly to occupy space that would otherwise be unavailable in the flat device architecture, enabling camera integration without reducing the display area or compromising the device's form factor.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a camera assembly is integrated into the housing, then image capture function is added, but the device form factor is compromised

Engineering Contradiction:
Improveimage capture functionVSAvoiddevice form factor
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The camera assembly is separated from the main housing body by being positioned in an extendable protrusion. This segmentation allows the camera to be integrated into the device while maintaining a clear distinction between the wearable body and the optical component, preserving the sleek form factor of the main device while adding camera functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protrusion extends in a direction substantially perpendicular to the display, creating a three-dimensional configuration that accommodates the camera assembly without expanding the device's footprint in the plane of the display. This maintains the device's thin profile and ergonomic form factor while enabling camera integration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
