Innovation Solution
A central laser machine with internet data communication hardware and software, combined with a laser chamber and molds that allow precise laser cutting and burning within a safe enclosure, connected to a central computer server for remote operation and updates, enabling efficient separation of glass layers and cutting of screen protectors to specific device dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional laser systems are used to separate back glass from underlying casing, then the adhesive can be burned, but the process requires substantial physical labor and force, is time-consuming, and poses safety risks to technicians
Solution Approach 1:
The system separates the laser burning function from the physical separation function. The laser machine burns the adhesive in one stage, and then the mold with lifting mechanism automatically separates the glass in a second stage, eliminating the need for technicians to apply physical force during the burning process.
Solution Approach 2:
A mold is introduced as an intermediary tool between the laser beam and the glass assembly. The mold contains the device during laser burning and provides automatic lifting mechanisms to separate the glass, acting as a mediator that eliminates direct technician involvement in both the burning and separation phases.
2Productivity
If laser systems are used to burn adhesive between back glass and underlying casing, then separation can be achieved, but toxic fumes are released which can poison and cause harm to persons who inhale them
Solution Approach 1:
The system converts the harmful toxic fumes into a contained byproduct. The mold encloses the burning area, capturing the toxic fumes generated during laser adhesive burning and preventing their release into the technician's breathing zone, thus transforming a harmful open process into a controlled enclosed process.
3Adaptability or versatility
If laser systems are frequently updated to accommodate new electronic mobile device models, then compatibility with new devices is maintained, but the updates require on-site software upgrades and mechanical setting changes which are costly, timely, and difficult
Solution Approach 1:
The mold is designed as a universal platform that can accommodate multiple device models. Different device configurations are achieved through programmable laser parameters and adjustable mold settings rather than requiring different physical hardware components, allowing one mold to serve multiple functions across various device models.
Solution Approach 2:
The system uses dynamically adjustable parameters (laser power, speed, pattern, and mold positioning) to adapt to different device models. This dynamic configurability allows the same physical mold to be reconfigured for new devices through software updates alone, eliminating the need for mechanical modifications.
4Reliability
If complete screen display replacement is performed instead of glass separation, then functional screens are restored, but the cost is high and the quality and specifications of the device are reduced when non-original displays are used
Solution Approach 1:
The system extracts only the damaged front glass layer from the intact display assembly. By selectively removing the cracked glass while preserving the underlying functional display components, the process enables replacement with lower-cost glass or screen protectors rather than requiring replacement of the entire expensive display assembly.
5Reliability
If back glass casing replacement is performed at official service agents, then proper repairs are achieved, but the cost is very high and the device is unavailable for a couple of days
Solution Approach 1:
The system replaces the traditional mechanical adhesive removal process with laser-based adhesive burning. This substitution enables precise, controlled separation of the back glass from the casing without requiring lengthy mechanical prying and forcing operations, significantly reducing repair time while maintaining proper repair quality.
