Cover Recess for NFC Unit Protection and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reading and recording apparatuses face challenges in user operability and near field communication (NFC) functionality, particularly in the placement and protection of NFC units, which can lead to damage and reduced rigidity, affecting communication efficiency and device usability.
Innovation Solution
The apparatus incorporates a cover mechanism with a near field communication unit integrated into the cover that opens and closes the document stand, featuring a metal plate for enhanced rigidity and protection, and strategically positions the NFC unit to avoid interference with the reading unit's movement, ensuring effective communication and improved user operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the near field communication unit is provided on the upper surface of the reading apparatus, then the user operability is improved, but the NFC unit is vulnerable to damage and the cover rigidity is reduced
Solution Approach 1:
The NFC unit is nested within a recess portion formed in the cover, allowing it to be embedded rather than surface-mounted. This nesting approach provides protective enclosure while maintaining the upper surface location for user accessibility, resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The solution transitions from surface-level placement to subsurface embedding by creating a recess portion in the cover. This dimensional change moves the NFC unit from the surface plane into the cover thickness, providing protection while preserving the upper surface location for user interaction.
2Strength
If a metal plate is added to enhance cover rigidity, then the structural integrity is improved, but it may interfere with near field communication
Solution Approach 1:
The metal plate is selectively positioned in specific regions of the cover where it provides rigidity enhancement without creating harmful electromagnetic fields that would interfere with NFC. By controlling the local placement and configuration of the metal plate, the design achieves structural strength while avoiding NFC interference.
3Ease of operation
If the NFC unit is exposed on the cover surface, then the communication functionality is accessible, but the unit is susceptible to damage
Solution Approach 1:
The NFC unit is nested within a recess portion in the cover, providing a protective enclosure that shields it from external damage while keeping it accessible for communication operations. The recess acts as a protective cavity that reduces vulnerability to physical harm.
Solution Approach 2:
The recess portion structure provides beforehand protection by creating a protective cavity that cushions and shields the NFC unit from potential damage before any harmful contact occurs. This pre-protective structure reduces the impact of external forces on the NFC unit.
