Emergency Button Lighting Groups for Multi-State Door Lock Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency buttons for securing escape routes only display locked and unlocked states, limiting the visualization of additional system states, which hampers user feedback and system awareness.
Innovation Solution
The emergency button system incorporates lamps that can be controlled in multiple groups, allowing for different lighting patterns and colors to indicate various system states, such as fire alarms, actuation status, and time delays, without requiring additional lighting components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting means are used to indicate door lock states, then the basic locked/unlocked states can be displayed, but the number of displayable system states is limited
Solution Approach 1:
The lighting means are divided into multiple controllable groups, where each group can be independently controlled to display different states. This segmentation allows the same physical lighting components to represent multiple system states by varying which groups are activated, thereby increasing the number of displayable states without adding more physical components.
Solution Approach 2:
The existing lighting means are made multi-functional by enabling them to indicate not only locked/unlocked states but also additional system states such as fire alarms, actuation status, and time delays. The same lighting infrastructure serves multiple indication purposes through different control patterns, achieving versatility without increasing device complexity.
2Adaptability or versatility
If additional lighting components are added to indicate more system states, then the number of displayable states increases, but the device complexity and cost increase
Solution Approach 1:
The patent makes the existing lighting means serve multiple functions by implementing intelligent control logic that assigns different meaning patterns to the same physical lights. Instead of adding more lights for each additional state, the system reuses the existing lighting infrastructure with enhanced control capabilities, thereby avoiding increased manufacturing complexity and cost while still achieving comprehensive state indication.
Solution Approach 2:
The system changes the control parameters of the existing lighting means (such as which groups are active, their intensity, or their timing patterns) to encode different system states. This parameter-based encoding allows the same physical components to represent multiple states without any physical modifications, maintaining ease of manufacture while increasing versatility.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user feedback by significantly increasing the number of states that can be displayed, providing clear and distinct visual cues for multiple system conditions, thus improving situational awareness and safety.
Implementation Method 1
The emergency button comprises at least lighting means with which a locked and an unlocked state of a door lock can be visualized. The lighting means glow green in the unlocked state and red in the locked state.
