Solution Overview

Problem

Existing light signaling devices for access gates, such as garage doors, do not effectively enhance safety by indicating the door's movement, differentiation between opening and closing, or illuminate the gate's perimeter, leading to potential safety hazards and unclear access status.

Innovation Solution

A light signaling device featuring elongated LED strips or elements placed along the access gate's perimeter, controlled by an electronic unit, which can indicate door movement, status, and potential malfunctions through color and sequence changes, integrated with a section bar for secure and efficient mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional acoustic and/or luminous signal is placed near the door, then the door movement can be signaled in poor lighting conditions, but the indicator does not indicate whether the door is being opened or closed, does not show the perimeter of the access gate, and does not substantially increase safety requirements

Engineering Contradiction:
ImprovesafetyVSAvoiddoor status information
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The lighting system is divided into multiple independent elongated lighting elements positioned at different locations (top, sides) of the gate perimeter. Each element can be controlled independently to provide different lighting patterns and information, allowing the system to convey door status, perimeter definition, and safety information simultaneously through segmented lighting zones

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of the gate perimeter are illuminated with different lighting characteristics. The top portion shows door movement, the side portions show gate extent, and specific zones can indicate opening/closing status. This local differentiation allows multiple types of information to be conveyed simultaneously without confusion

Inventive Principle:
Principle #3Local quality

2Illumination intensity

If a bright flashing indicator is used to signal door movement, then visibility in poor lighting conditions is improved, but the indicator provides undifferentiated signaling that does not distinguish between opening and closing operations

Engineering Contradiction:
ImprovevisibilityVSAvoiddoor operation direction
Core Design Contradiction:
Illumination intensityVSLoss of information

Solution Approach 1:

The lighting elements can change color or lighting pattern to indicate different door operations. For example, one color pattern indicates door opening while another indicates door closing, allowing the system to maintain high visibility while conveying directional information through color or pattern differentiation

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The lighting elements employ different periodic patterns (flashing frequencies, on/off sequences) to indicate different door operations. This allows the system to maintain attention-grabbing periodic illumination while encoding directional information in the timing pattern itself

Inventive Principle:
Principle #19Periodic action

3Loss of information

If elongated lighting elements are placed along the gate perimeter, then the gate perimeter can be illuminated and door movement signaled, but the device complexity increases compared to traditional point indicators

Engineering Contradiction:
Improveperimeter visibilityVSAvoidlighting system structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The lighting elements are implemented as flexible LED strips that can be easily mounted along the gate perimeter. This flexible film-based approach simplifies installation compared to rigid lighting structures while providing continuous perimeter illumination, reducing the practical complexity despite the extended coverage

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The same elongated lighting elements serve multiple functions: defining the gate perimeter, indicating door movement, showing opening/closing status, and providing safety illumination. This multi-functionality reduces the need for separate devices for each function, thereby reducing overall system complexity despite the extended lighting coverage

Inventive Principle:
Principle #6Universality (Multi-functionality)
