Solution Overview

Problem

Computing devices with thin display bezels face limitations in image capture quality due to the restricted depth of camera/lens assemblies, which restricts the size and capability of integrated image capture devices like cameras.

Innovation Solution

A computing device design featuring a moveable lens assembly with an extension member that allows the lens to be positioned outside or within the display bezel, increasing the distance between the lens and image sensor for improved light gathering capabilities and accommodating larger, higher-quality lenses within a thin bezel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the display bezel is made thin to maintain a sleek device form factor, then the device aesthetics and portability are improved, but the depth available for the camera/lens assembly is reduced, limiting image capture quality

Engineering Contradiction:
Improvedisplay bezel thicknessVSAvoidimage capture quality
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The patent implements a movable lens assembly that can dynamically change its position between a retracted state (within the bezel) and an extended state (protruding from the bezel). This dynamic mechanism allows the optical system to achieve greater lens-to-sensor distance when needed for high-quality image capture, while maintaining a thin profile during normal use. The lens assembly moves along an optical axis perpendicular to the display surface, enabling on-demand adjustment of optical path length.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention utilizes the third dimension (depth) by allowing the lens assembly to protrude outward from the bezel surface. Instead of being constrained to a two-dimensional plane within the bezel, the optical components can extend in the Z-direction (perpendicular to the display), effectively increasing the available optical path length without compromising the thinness of the bezel's main structure.

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

2Manufacturing precision

If a larger lens and image sensor are used to improve light gathering and image quality, then image capture capabilities are enhanced, but the depth and space required within the display bezel increases

Engineering Contradiction:
Improveimage capture qualityVSAvoidcamera assembly depth
Core Design Contradiction:
Manufacturing precisionVSVolume of moving object

Solution Approach 1:

The patent employs a movable lens assembly that can extend beyond the bezel when high-quality image capture is required. This dynamic extension mechanism allows larger lenses and sensors to be accommodated by providing the necessary depth only when needed, rather than requiring constant deep space within the bezel structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lens assembly is designed to nest within the display bezel when not in use, similar to a nested doll structure. The optical components can be retracted into the bezel cavity, occupying minimal space during normal device operation, and only extend outward when image capture functionality is activated.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

In one general aspect, the computing device can include a base portion, and a display portion moveably coupled to the base portion, the display portion including a display bezel and an image sensor disposed within the display bezel. The computing device can also include an extension member coupled to the display portion and associated with a lens. The extension member can be configured to move at least a portion of the lens in a direction away from the image sensor to a position disposed outside of the display bezel and to move the portion of the lens in a direction towards the image sensor to a position disposed within the display bezel.
