Rear Window Security Grid With LED Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear window security grids for police vehicles obstruct visibility and allow potential theft of critical items due to inadequate design, leading to safety concerns and increased risk of ambush shootings and rear-end collisions.
Innovation Solution
A rear window security grid and light system featuring a non-linear frame with LED chevrons and a diamond pattern that enhances visibility, prevents item removal, and provides clear signaling to oncoming traffic, utilizing a grid with adjustable cross units and LED lighting for improved safety and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rear window security grid is installed, then security against item theft is improved, but visibility for the driver is obstructed
Solution Approach 1:
The grid is segmented into individual cross units with non-linear orientations, where each unit consists of bars positioned at angles rather than forming a complete linear grid. This segmentation allows light to pass through the gaps between bars while still presenting an obstructive pattern to potential thieves, thus maintaining both visibility and security functions
Solution Approach 2:
The cross units are arranged in a non-linear, asymmetric pattern rather than a uniform grid. The bars within each cross unit are oriented at different angles, creating an irregular pattern that obstructs theft attempts while allowing sufficient light transmission for driver visibility through the rear window
2Ease of operation
If an SUV is used instead of a sedan, then operational capability and visibility are improved, but security against theft and ambush is reduced
Solution Approach 1:
The security grid is installed in advance on the SUV's rear window to prevent potential theft or ambush attacks. The grid structure with its non-linear cross units creates physical obstruction that deters thieves from breaking in and stealing equipment, while the asymmetric design ensures it doesn't compromise the SUV's operational visibility and capability
3Reliability
If horizontal bars are used in the security grid, then security is improved, but visibility during backing up is impeded
Solution Approach 1:
Instead of using straight horizontal bars, the grid employs non-linear cross units with bars oriented at various angles. This curved or angled arrangement allows light to pass through more effectively in the vertical direction needed for backing up visibility, while still maintaining security function through the angled obstruction pattern

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system improves rear visibility, enhances officer safety by preventing item theft, and reduces the risk of rear-end collisions by providing clear and effective signaling to oncoming traffic through its LED patterns and secure design.
Implementation Method 1
Upon each left member and each right member, the invention has at least one light emitting diode, or one LED

AI summary
A rear window security grid and light system has a frame, a grid within it, cross units forming the grid, and a left member and a right member in each cross unit. The grid has a primary cross unit centered upon the frame. Upon each left member and each right member, the invention has at least one light emitting diode, or LED. The LED operate from the power supply of a vehicle or a separate battery. The LED provide at least three patterns: left chevron, right chevron, and a letter X. Each left member has an upper portion and a lower portion and each right member has an upper portion and a lower portion with LED upon each portion. The controls allow for selection of the chevron's direction, interval speed to simulate motion, and operation of the letter X upon each cross unit.
