Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromechanical locking devices lack user-friendly and safe operation methods, as they often require mechanical coding and do not provide clear feedback on access authorization, leading to potential misuse or inefficiency.
Innovation Solution
A key with an integrated light device that uses color, flashing patterns, and light intensities to communicate access authorization status, energy storage status, and connection information, powered by an energy storage device and equipped with a wireless communication module for seamless interaction with locking devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a previously known key for an electromechanical locking device is used, then the key can transmit electronic data to the locking device, but the user receives no visual feedback on access authorization status
Solution Approach 1:
The patent applies color changes by incorporating a light device with multiple LEDs that emit different colors (red, yellow, green, blue, white) to represent various access authorization states. The electronic controller activates specific LEDs based on the access status, providing intuitive visual feedback to the user without requiring complex display screens or additional components.
2Loss of information
If the light device uses multiple colors and flashing patterns to convey information, then the information transmission capability is improved, but the energy consumption increases
Solution Approach 1:
The patent implements periodic action through flashing light patterns where LEDs are activated in sequences rather than continuously. Different flashing patterns (e.g., alternating colors, pulsing sequences) encode multiple pieces of information while minimizing energy consumption by keeping LEDs off during non-active periods. The electronic controller manages these periodic activations based on the specific information that needs to be communicated.
