Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing protection cases for intelligent terminals, such as smartphones, are oversized and structurally complex due to the inclusion of mechanical switching elements, RFID chips, and RFID coils, which complicates the design and increases the overall size.
Innovation Solution
A protection case design featuring a housing with integrated RFID coils, RFID chips, and switching elements, where the RFID coils are partially disposed on a base and the chips are connected in series with switching elements, allowing for compact integration and efficient energy transmission without the need for external power, and the use of a reinforcing sheet to enhance structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical switching elements, RFID chips and RFID coils are provided on the protection sleeve, then the functionality to trigger programs and applications is improved, but the structure complexity and overall size increase
Solution Approach 1:
The patent combines the mechanical switching element, RFID chip, and RFID coil into a single integrated protection sleeve structure. The switching element is positioned to directly contact the RFID chip when pressed, eliminating the need for separate mounting structures and wiring harnesses, thereby reducing overall complexity while maintaining full functionality.
Solution Approach 2:
The protection sleeve serves multiple functions simultaneously: it acts as a mechanical switch trigger, an RFID communication interface, and a protective cover. This multi-functionality eliminates the need for separate components for each function, reducing the number of parts and simplifying the overall structure.
2Adaptability or versatility
If mechanical switching elements, RFID chips and RFID coils are provided on the protection sleeve, then the functionality to trigger programs and applications is improved, but the overall size of the protection sleeve increases
Solution Approach 1:
The RFID chip is embedded within the protection sleeve material, and the RFID coil is integrated into the same structure. The mechanical switching element is positioned to directly contact the embedded RFID chip when pressed. This nested arrangement allows all components to occupy the same spatial volume, significantly reducing the overall size compared to separate mounting.
Solution Approach 2:
By merging all three components (switching element, RFID chip, RFID coil) into a single integrated structure, the patent eliminates the need for separate mounting spaces and connection pathways, thereby minimizing the overall volume while maintaining full functionality.
3Adaptability or versatility
If RFID coils and RFID chips are connected in series with switching elements, then the circuit functionality is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent integrates the RFID chip and switching element into a single unified structure where the switching element directly contacts the RFID chip when pressed. This eliminates the need for separate wiring and connection processes, significantly simplifying manufacturing while maintaining the required circuit functionality.
Solution Approach 2:
The patent replaces complex electrical connection systems with a direct mechanical contact mechanism. When the switching element is pressed, it mechanically contacts the RFID chip to complete the circuit, eliminating the need for intricate wiring harnesses and connection processes.
