Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact memory devices for monuments require close proximity for access and allow only single-user access, limiting information sharing.
Innovation Solution
A wireless communication device embedded in a monument that uses wireless power reception and transmission, enabling multiple users to access information via electromagnetic signals without physical contact, and includes a hermetically sealed casing for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact memory devices are used for monuments, then information can be stored and accessed, but users must be in very close proximity to access the information and only one user can read at a time
Solution Approach 1:
The patent replaces the mechanical contact-based memory reading system with a wireless electromagnetic field-based system. The memory device uses wireless communication protocols to transmit information to user devices without requiring physical contact or close proximity, thereby resolving the contradiction between access distance and information access efficiency
Solution Approach 2:
The memory device is designed to support multiple user devices simultaneously through wireless communication, making it universal in terms of user access. Multiple users can access the monument information at the same time from different distances, eliminating the single-user limitation of contact memory devices
2Reliability
If contact memory devices are used, then information is stored locally, but access is limited to a single user at a time
Solution Approach 1:
The system replaces mechanical contact-based data access with wireless electromagnetic communication, enabling multiple user devices to access the stored information simultaneously without interfering with each other or the integrity of the stored data
Solution Approach 2:
The patent introduces wireless communication signals as an intermediary between the memory device and multiple user devices. This intermediary enables simultaneous access by multiple users while the memory device maintains reliable local storage of information
3Adaptability or versatility
If wireless communication is implemented for monument information, then multiple users can access simultaneously, but power supply becomes a challenge at remote locations
Solution Approach 1:
The memory device is designed to harvest energy from the environment, particularly from wireless communication signals themselves. The device can extract power from the electromagnetic signals used for communication, enabling it to operate autonomously at remote monument locations without external power infrastructure
Solution Approach 2:
The wireless communication signals serve a dual function as both data transmission carriers and power sources. The electromagnetic signals act as an intermediary that simultaneously provides information transfer and energy transfer to the memory device
4Ease of operation
If the memory device is exposed at the monument site, then it can be accessed, but it is vulnerable to environmental damage and theft
Solution Approach 1:
The patent employs a transparent or translucent protective casing that encloses the memory device. This shell protects the device from environmental factors such as weather and physical damage while allowing wireless communication signals to pass through, maintaining accessibility without compromising protection
