Solution Overview

Problem

Existing portable information handling systems face challenges in disassembling displays from housings without causing damage, leading to component waste and increased manufacturing and maintenance costs due to the use of adhesive tape, which complicates assembly and repair.

Innovation Solution

A sliding structure is implemented on the display panel that engages under a lip of the housing, allowing for easy removal and reassembly without adhesive, using L-shaped members or pins that fit into channels to secure the display in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If adhesive tape is used to couple the display to the housing, then minimal vertical and lateral space is required, but disassembly becomes difficult and can damage the display panel

Engineering Contradiction:

Improvespace required for display couplingVSAvoiddisplay disassembly and repairability

Core Design Contradiction:

Volume of moving objectVSEase of repair

Solution Approach 1:

The coupling mechanism is divided into separate components: a coupling structure with lips on the housing and corresponding coupling members on the display panel. This segmentation allows the display to be coupled and decoupled as discrete units without damage, resolving the contradiction between space efficiency and repairability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coupling mechanism transitions from a static adhesive bond to a dynamic mechanical coupling that can be easily engaged and disengaged. The sliding structure allows the display to move between coupled and decoupled states, enabling repair while maintaining minimal space requirements.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If adhesive tape is used to secure the display, then assembly is simplified, but component waste increases when repair fails

Engineering Contradiction:

Improveassembly simplicityVSAvoidcomponent waste from failed repairs

Core Design Contradiction:

Ease of manufactureVSLoss of substance

Solution Approach 1:

The mechanical coupling mechanism enables recovery and reuse of the display panel after decoupling, whereas adhesive tape typically results in component waste. The coupling members can be repeatedly engaged and disengaged without damage, reducing substance loss.

Inventive Principle:

Principle #34Discarding and recovering

3Shape

If the display is coupled with minimal structure to achieve zero bezel appearance, then aesthetics and housing size are improved, but the display panel becomes vulnerable to damage during removal

Engineering Contradiction:

Improvezero bezel appearance and housing sizeVSAvoiddisplay panel survival during disassembly

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The coupling members act as intermediary elements between the display panel and housing, providing a protective interface that enables safe coupling and decoupling. These intermediaries allow the display to achieve minimal bezel appearance while protecting against damage during removal through controlled mechanical engagement.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information handling system display removably couples to a housing with a sliding structure of the display that engages a coupling structure disposed at opposing sides of the housing. For example, the sliding structure is a member that aligns under a lip formed in the coupling structure. In one embodiment, the sliding structure comprises plural pins extending from opposing sides of the display to enter channels at the side of the housing that direct the pins under a lip at the base of the channel.
