Solution Overview

Problem

Current technologies lack effective solutions for dynamically repairing scratched mobile device screens, particularly in a cost-efficient and on-demand manner, as the increasing variety of devices makes traditional inventory-based methods prohibitive and existing screen protectors only address prevention rather than repair.

Innovation Solution

A system comprising a CNC machine equipped with a candle bit and staging area, using a rotating end-mounted applicator coated with a paste to polish and repair mobile device screens, with sensors monitoring temperature, pressure, and rotation rate to optimize the process, and a kit including pre-treatment and oleophobic coatings for comprehensive screen management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional inventory-based methods are used to store screen protectors for various devices, then device protection can be provided, but the cost becomes prohibitive due to the increasing variety of devices

Engineering Contradiction:
Improvedevice compatibilityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system dynamically adjusts the screen protector fabrication process based on the specific device dimensions and characteristics. The CNC machine receives real-time dimensional data from the device and automatically adjusts cutting parameters, creating a customized screen protector on-demand without requiring pre-stored inventory for each device model.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system measures the device dimensions directly during the screening process and uses those measurements to automatically generate and fabricate the appropriate screen protector. This self-measuring, self-adjusting approach eliminates the need for manual inventory management across multiple device models.

Inventive Principle:
Principle #25Self-service

2Reliability

If screen protectors are applied to protect against scratches, then screen protection is provided, but there is no solution for repairing screens after scratches occur

Engineering Contradiction:
Improvescreen protectionVSAvoidrepair capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs multiple functions in sequence: first screening the device to detect scratches, then fabricating a custom screen protector, and finally applying repair compounds to address the scratches. This multi-functional approach combines prevention and repair capabilities in a single integrated system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system detects and screens for scratches before the screen protector is applied. By identifying scratch locations and characteristics in advance, the system can pre-position repair compounds and adjust the screen protector design to accommodate the damaged areas, ensuring both protection and repair are addressed.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a CNC machine with sensors and rotating applicator is used to polish screens, then real-time dynamic repair is achieved, but the device complexity increases

Engineering Contradiction:
Improvereal-time repair capabilityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system replaces manual screen repair processes with an automated CNC machine that uses computer-controlled movements, sensor feedback, and automated applicator mechanisms. This mechanical automation enables real-time repair capability while the control system manages the complexity through software integration.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Sensors mounted on the CNC machine continuously monitor the screen surface during the polishing and repair process, providing real-time feedback on scratch removal effectiveness and surface quality. This feedback loop allows the system to automatically adjust polishing parameters and repair compound application to achieve optimal results.

Inventive Principle:
Principle #23Feedback

AI summary

Techniques for polishing and repairing a device's surface are disclosed. An applicator is coated with a paste using a CNC machine. The applicator is attached to a candle bit of the CNC machine, and a device is disposed on a staging area of the CNC machine. The applicator and/or the staging area are moved using the CNC machine to position the applicator above a selected area of the surface of the device. The applicator is rotated at a predetermined rate using the CNC machine. The applicator and/or the staging area are moved using the CNC machine to cause the applicator to contact the surface. The applicator and/or the staging area are moved using the CNC machine in accordance with a predetermined pattern, which is selected to enable the paste and the applicator to polish the surface of the device, including a scratch on the surface.
