Adjustable Garage Door Sensor Cover for Light and Debris Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garage door sensors, particularly photo eye sensors, are affected by ambient lighting and often malfunction due to debris accumulation, requiring customizable and non-adjustable covers that are difficult to install and maintain.
Innovation Solution
A removable and adjustable cover for garage door sensors, designed to slide and fit securely over the sensor, allowing for adjustment of the distance from the sensor and featuring a fastener system for secure attachment, enabling easy installation, maintenance, and debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is placed over the sensor to block ambient light, then sensor malfunction caused by ambient light is reduced, but the cover becomes difficult to customize and install
Solution Approach 1:
The cover is designed with a universal fit mechanism that can accommodate different sensor types and configurations. The adjustable positioning system allows a single cover design to work across multiple sensor models, eliminating the need for custom covers for each sensor type while maintaining reliability.
Solution Approach 2:
The cover incorporates adjustable positioning features that allow it to adapt to different sensor configurations and environmental conditions. This dynamic adjustability enables the same cover design to serve multiple purposes and fit various sensor types without requiring customization.
2Reliability
If a cover is placed over the sensor to block ambient light, then sensor malfunction caused by ambient light is reduced, but the cover becomes difficult to install
Solution Approach 1:
The cover is divided into multiple components including the main cover body, mounting brackets, and adjustable positioning elements. This segmentation allows for easier handling, alignment, and installation compared to a single-piece cover, reducing installation difficulty while maintaining ambient light blocking effectiveness.
Solution Approach 2:
The cover includes adjustable positioning features and flexible mounting options that simplify the installation process. These dynamic elements allow installers to easily adjust the cover to fit different sensor configurations without requiring complex installation procedures.
3Reliability
If a fixed cover is used over the sensor, then ambient light blocking is provided, but the cover cannot be adjusted for optimal performance
Solution Approach 1:
The cover incorporates adjustable positioning mechanisms that allow users to modify the cover's position and orientation to achieve optimal ambient light blocking for different environmental conditions and sensor configurations, while maintaining reliable protection.
Solution Approach 2:
The adjustable cover design provides multiple positioning options and configurations, enabling a single cover to adapt to various sensor types, mounting locations, and environmental conditions, thereby enhancing both adaptability and ambient light blocking effectiveness.
4Reliability
If a cover is placed over the sensor to protect from debris, then sensor malfunction is reduced, but the cover itself becomes covered with debris requiring maintenance
Solution Approach 1:
The cover is designed as a separate, removable component that can be easily detached from the sensor assembly. This segmentation allows for simple maintenance where the cover can be removed, cleaned, or replaced without affecting the sensor, making debris removal easier compared to integrated designs.
Solution Approach 2:
The cover is extracted as a separate maintenanceable component from the sensor assembly. This extraction allows the cover to be independently removed for cleaning or replacement when covered with debris, simplifying maintenance procedures while continuing to protect the sensor from debris during normal operation.
