IC Card Breakage Lugs Prevent Frame Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reuse of disposable frame-pieces as adapters for smaller SIM card formats leads to substantial deterioration of contact slides in mobile device slots, necessitating a solution to prevent reuse and protect these components.
Innovation Solution
Integrated circuit cards with pre-cut lines and breakage lugs are designed to intentionally break disposable frame-pieces, preventing reuse and ensuring safe separation of sectors, thereby protecting contact slides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If disposable frame-pieces are designed to be reusable as adapters for smaller SIM card formats, then versatility and ease of operation are improved, but contact slides in mobile device slots suffer substantial deterioration
Solution Approach 1:
The frame-piece is segmented into multiple parts through pre-cut lines that allow it to be broken into separate sections. This segmentation enables the frame to adapt to different SIM card formats while preventing reuse, as the broken pieces cannot be reassembled into a functional adapter.
Solution Approach 2:
The frame-piece is pre-configured with break lines and breakable portions that are designed to break during the first adaptation use. This preliminary action ensures that the frame cannot be reused as an adapter, thereby protecting contact slides from deterioration caused by repeated insertions and removals.
2Object-affected harmful factors
If disposable frame-pieces are made breakable to prevent reuse, then contact slides are protected from deterioration, but the frame-piece cannot be reused as an adapter
Solution Approach 1:
The frame-piece is designed as a disposable component with a limited lifecycle. It is intentionally made breakable so that it can be used once as an adapter and then discarded, preventing the harmful effects of reuse on contact slides while maintaining its adaptability function during its intended single use.
Solution Approach 2:
The frame-piece is designed to be discarded after a single use. The breakable portions ensure that the frame cannot be recovered or reused as an adapter, thereby protecting the contact slides from deterioration while the frame performs its adaptation function during its intended lifecycle.
3Object-affected harmful factors
If pre-cut lines are added to enable breaking of frame-pieces, then reuse is prevented and contact slides are protected, but device complexity increases
Solution Approach 1:
The frame-piece structure is segmented with pre-cut lines that create weak points designed to break during use. This segmentation adds minimal structural complexity while effectively preventing reuse, as the break lines create irreversible separation that cannot be easily reassembled.
Solution Approach 2:
The frame-piece has non-uniform structural properties with specific breakable portions and break lines located at strategic positions. This local variation in quality (thinner sections, pre-scored lines) enables controlled breaking while maintaining overall structural integrity during single use, adding minimal complexity where needed.
