Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual installation method is used, then operation flexibility is maintained, but labor cost increases and efficiency decreases
Solution Approach 1:
The automatic screen protector attaching machine is divided into multiple independent functional modules: a placing device for holding mobile phones, a cleaning device for surface preparation, a film grabbing device for picking up screen protectors, and a first displacement device for positioning. Each module operates independently but coordinates with others, enabling automated installation while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces a sliding belt as an intermediary transmission mechanism that connects the placing device with the film grabbing device. The sliding belt transfers mobile phones between stations and coordinates the timing of operations, serving as a mediator that synchronizes the actions of different modules without requiring complex direct control mechanisms between them.
2Extent of automation
If automated machine is introduced, then labor cost decreases, but device complexity increases
Solution Approach 1:
The film grabbing device is designed with multi-functionality, capable of both picking up screen protectors from the storage device and precisely positioning them onto the mobile phone screen. The device integrates gripping, positioning, and placement functions in a single mechanism, reducing the need for separate specialized components and simplifying the overall automated system.
Solution Approach 2:
The storage device pre-arranges screen protectors in a specific orientation and position before the attachment process begins. The film grabbing device simply needs to pick up pre-positioned protectors rather than searching or orienting them during the attachment process, reducing the complexity of the grabbing mechanism while maintaining automated operation.
3Manufacturing precision
If cleaning device is added, then attachment quality improves, but device complexity increases
Solution Approach 1:
The cleaning function is extracted as a separate, dedicated module rather than being integrated into the main attachment mechanism. The cleaning device operates independently to prepare the phone screen surface, then the cleaned phone is transferred to the attachment station. This separation allows the cleaning system to be simple and specialized without adding complexity to the film grabbing and positioning mechanisms.
