Solution Overview
Problem
Conventional lighting systems fail to effectively guide individuals to emergency exits or specific rooms, especially in situations like heavy smoke or disorientation, and can be too bright for older people or those with dementia, disrupting sleep patterns.
Innovation Solution
A lighting module with individually controllable lighting elements, activated by sensors such as movement or brightness sensors, to provide targeted and adaptive lighting guidance, ensuring safe navigation while minimizing energy consumption and avoiding harsh lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional room lighting is switched on to illuminate the entire room, then people can see the conditions in the room, but no specific guidance is provided to direct people to an emergency exit or specific door
Solution Approach 1:
The lighting system is divided into multiple individually controllable lighting elements (e.g., LED modules) arranged in sequences or patterns. Instead of illuminating the entire room uniformly, specific segments are activated to create directional light paths or arrows that guide people to exits, providing precise directional information while using fewer lights.
Solution Approach 2:
Different regions of the lighting system are assigned different functions: some areas provide general illumination while others create directional guidance patterns. The lighting elements can be selectively activated to create localized light paths, arrows, or sequences that indicate escape routes, making the lighting serve multiple purposes with different qualities in different locations.
2Illumination intensity
If conventional room lighting is switched on to provide illumination, then the entire room is lit, but the lighting is perceived as unpleasant or too bright, especially by older people or people with dementia
Solution Approach 1:
The lighting system dynamically adjusts its characteristics based on real-time sensor input. Motion sensors detect when someone is present and activate only the necessary lighting elements at appropriate brightness levels. The system can create moving light patterns or sequences that guide people without requiring sustained high illumination, reducing overall brightness exposure while maintaining effectiveness.
Solution Approach 2:
Instead of continuous illumination, the system uses periodic or intermittent lighting activation. Lighting elements are switched on only when motion is detected and deactivated when areas are unoccupied. This reduces cumulative light exposure and energy consumption while maintaining safety and comfort for vulnerable populations.
3Reliability
If conventional lighting systems are used to guide people to exits, then the entire room is illuminated, but energy consumption is high
Solution Approach 1:
The lighting system is segmented into independently controllable modules or zones. Only the specific segments required for guidance are activated based on sensor detection, rather than illuminating the entire space. This allows the system to maintain reliable directional guidance while minimizing the number of active lighting elements and reducing energy consumption.
Solution Approach 2:
The lighting system automatically activates and deactivates lighting elements based on sensor input without requiring manual control. Motion sensors detect presence and trigger the appropriate lighting pattern, and the system turns off lights when areas are unoccupied, providing energy-efficient operation while maintaining guidance reliability.
4Reliability
If lighting elements are activated continuously to ensure guidance availability, then people can always find their way, but energy consumption increases and sleep patterns are disrupted
Solution Approach 1:
The lighting system operates periodically rather than continuously, activating only when motion is detected and deactivating when areas are unoccupied. This ensures guidance is available when needed while minimizing unnecessary light exposure that would disrupt sleep patterns and waste energy.
Solution Approach 2:
The system uses sensor feedback (motion detection, ambient light levels) to automatically control lighting activation. When sensors detect presence or darkness, the system activates appropriate lighting elements; when areas are unoccupied or sufficiently lit, lights are turned off, optimizing the balance between guidance availability and energy/sleep conservation.
