Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices for locks are cumbersome and require multiple key fobs, lacking a single, convenient solution for unlocking various locking devices.
Innovation Solution
A customizable, adjustable finger ring with an internal RF transmitter that wirelessly communicates with locks to unlock them upon approach, eliminating the need for multiple keys or key fobs by sending an RF signal when in proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple key fobs are used for different locks, then each lock can be unlocked reliably, but the device becomes cumbersome and difficult to carry
Solution Approach 1:
The patent applies universality by designing a single key fob that can unlock multiple types of locks (door locks, car locks, padlocks, mailbox locks) through programmable RF transmitter chips. The key fob stores multiple coded signals that correspond to different lock types, allowing one device to perform multiple locking/unlocking functions that previously required separate key fobs for each lock.
Solution Approach 2:
The patent merges the functionality of multiple separate key fobs into a single integrated device. By combining multiple RF transmitter chips with different codes into one key fob unit, the patent eliminates the need to carry and manage multiple separate key fobs while maintaining the ability to unlock each specific lock type reliably.
2Adaptability or versatility
If multiple keys and key fobs are carried, then all locks can be accessed, but the burden of carrying and finding them increases
Solution Approach 1:
The patent creates a universal key fob that can access various locking devices through programmable RF signals. The key fob can be programmed with multiple different codes corresponding to different lock types, providing adaptability to various locking scenarios while maintaining a single convenient device to carry.
Solution Approach 2:
The patent enables the key fob to serve itself by automatically detecting the type of lock and transmitting the appropriate coded signal without requiring manual intervention. The user simply approaches the lock and the key fob automatically identifies and transmits the correct code, eliminating the need to manually select or switch between different key fobs.
3Ease of operation
If keyless-entry keyfobs are used instead of keys, then convenience is improved, but the unwieldiness of carrying them increases
Solution Approach 1:
The patent replaces traditional mechanical keys with wireless RF-based keyless entry technology. The key fob uses radio frequency signals to communicate with the lock's receiver, eliminating the need for physical key blades and mechanical locking mechanisms. This substitution maintains convenience while reducing the bulk and weight compared to traditional key fobs.
