Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional tablet devices have thick bezels that hinder repairability and require specialized tools or damage for disassembly, limiting their usability and aesthetics.

Innovation Solution

A locking mechanism with locking plates that securely attach tablet halves, allowing for a thinner bezel and easier disassembly for repair and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape and screws are used to assemble tablet halves, then the two halves are held together securely, but the device cannot be disassembled for repair without damage or specialized equipment

Engineering Contradiction:

Improveassembly securityVSAvoiddisassembly ease

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The locking mechanism is divided into separate components: locking plates attached to one tablet half, corresponding holes in the other half, and release holes for tool access. This segmentation allows the assembly to be securely locked during use but easily disassembled by inserting a tool through the release holes to manipulate the locking plates.

Inventive Principle:

Principle #1Segmentation

2Strength

If a wide adhesive tape is used to bond tablet halves, then sufficient bonding strength is achieved, but the bezel must be thick which reduces display area and aesthetics

Engineering Contradiction:

Improvebonding strengthVSAvoidbezel thickness

Core Design Contradiction:

StrengthVSLength of stationary object

Solution Approach 1:

The patent replaces the chemical bonding mechanism (adhesive tape) with a mechanical locking system consisting of locking plates and holes. This mechanical system provides the necessary bonding strength while allowing for a thinner bezel design, as the locking mechanism does not require the same bezel thickness that adhesive tape does.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If conventional assembly methods are used, then the tablet device is securely assembled, but the device lacks repairability and requires specialized equipment for disassembly

Engineering Contradiction:

Improveassembly securityVSAvoiddisassembly operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces intermediary elements - the release holes and tool - that mediate between the user and the locking mechanism. The release holes provide access points for a simple tool (such as a paperclip or specialized tool) to interact with the locking plates, enabling easy disassembly without requiring specialized equipment or damaging the device.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Embodiments of the invention provide a locking mechanism for a tablet computer, the locking mechanism comprising at least three locking plates having an open position and a locked position, wherein when the locking plates are in the locked position, the first tablet half of the tablet computer is coupled to the second half of the tablet computer. The locking plates enable the tablet computer to have a thinner bezel than conventional tablet computers which facilitates repair of the tablet computer.
