Bracket Pin Connection for Cover Glass Durability

Solution Overview

Problem

The increasing demand for portable and compact computing devices has led to smaller bezels and larger visual displays, compromising the durability and reworkability of computing devices, as conventional methods for securing the cover glass to the chassis are inadequate.

Innovation Solution

A connection device comprising a first bracket affixed to the cover glass and a second bracket fixed to the chassis, secured by a pin and optionally a compressible member, which limits movement between the brackets, enhancing the securement of the cover glass to the chassis while allowing for reworkability and concealing fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the bezel size is reduced and visual display is enlarged, then the portability and compact design are improved, but the durability and reworkability of the computing device deteriorate

Engineering Contradiction:

Improvedevice compactnessVSAvoiddevice durability

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The connection device is divided into separate components: a first bracket attached to the cover glass, a second bracket attached to the chassis, and a pin connecting them. This segmentation allows each component to be optimized independently while maintaining overall device compactness and durability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pin is positioned through openings in both brackets, creating a nested connection where the pin passes through the first bracket and is received by the second bracket. This nested arrangement provides secure attachment while minimizing the space required for the connection mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of moving object

If the bezel size is reduced and visual display is enlarged, then the portability and compact design are improved, but the reworkability of the computing device deteriorates

Engineering Contradiction:

Improvedevice compactnessVSAvoiddevice reworkability

Core Design Contradiction:

Volume of moving objectVSEase of repair

Solution Approach 1:

The connection device is divided into separate components: a first bracket attached to the cover glass, a second bracket attached to the chassis, and a pin connecting them. This segmentation allows each component to be optimized independently while maintaining overall device compactness and durability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pin and bracket design allows for easy removal and reuse of components. The pin can be removed from the openings in the brackets, enabling the cover glass assembly to be separated from the chassis for repair or replacement, and then reconnected by reinserting the pin.

Inventive Principle:

Principle #34Discarding and recovering

3Ease of manufacture

If conventional methods for securing cover glass are used, then the manufacturing process is simple, but the securement of cover glass to chassis is inadequate

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcover glass securement

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The connection device is divided into separate components: a first bracket attached to the cover glass, a second bracket attached to the chassis, and a pin connecting them. This segmentation allows each component to be optimized independently while maintaining overall device compactness and durability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The compressible member is positioned between the first bracket and the second bracket to provide resilient contact. This curved or flexible element deforms under compression to maintain constant contact force, ensuring reliable securement while accommodating manufacturing tolerances and assembly variations.

Inventive Principle:

Principle #14Spheroidality (Curvature)
