Solution Overview

Problem

Existing vehicular LED light bar covers are cumbersome to install and remove, often leading to safety hazards, exposure to dust and heat, loss of illuminating power, and space constraints, as they require manual handling and may not securely attach, causing damage or violations.

Innovation Solution

A light bar cover with hinges, hooks, magnets, and electromagnets that allows for one-handed operation, secure attachment, and automatic opening/closing, featuring a reflector film to maximize light efficiency and minimize storage needs, with an aerodynamic design for reduced air resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a standard cover is used for the light bar, then the light bar can be covered, but the cover is not securely attached and can slip out at high speed creating hazards

Engineering Contradiction:

Improvecover attachment securityVSAvoidsafety hazard from loose cover

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cover attachment system is segmented into multiple independent securing points (hooks at front and rear ends) rather than relying on a single attachment method. This segmentation ensures that even if one attachment point fails, the cover remains secured to the light bar.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple attachment mechanisms (hooks, magnet assemblies, and fastening structures) are merged into a unified cover system. The combination of mechanical hooks and magnetic assemblies works together to provide redundant securing, preventing the cover from slipping out during high-speed operation.

Inventive Principle:

Principle #5Merging (Combining)

2Ease of operation

If the light bar cover is manually removed and reattached, then the cover can be installed or removed, but the driver must exit the vehicle which can result in injury or damage

Engineering Contradiction:

Improvecover installation/removal convenienceVSAvoidinjury or damage risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The manual mechanical attachment system is replaced with an automated electromagnetic attachment system. Electromagnets and control mechanisms enable the cover to be automatically secured or released from inside the vehicle, eliminating the need for the driver to exit and manually handle the cover.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cover system incorporates self-securing features through automated control mechanisms. The cover can automatically attach to or detach from the light bar through integrated motors and control systems, allowing the driver to operate it from inside the vehicle without manual intervention.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the light bar face is exposed without cover, then the light bar is accessible, but it is exposed to dust, scratches and heat that can shorten its life

Engineering Contradiction:

Improvelight bar accessibilityVSAvoiddust, scratches and heat exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The light bar cover acts as a protective shell that can be flexibly opened or closed. When closed, it forms a protective barrier against dust, scratches, and heat while allowing the light bar to remain accessible when opened, balancing protection with accessibility.

Inventive Principle:

Principle #30Flexible shells and thin films

4Ease of operation

If the light bar is completely exposed without proper casing, then the light bar is fully accessible, but it loses significant amounts of illuminating power

Engineering Contradiction:

Improvelight bar accessibilityVSAvoidilluminating power loss

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The cover serves as a protective shell that can be configured to either expose or shield the light bar. When closed, it maintains the illuminating power by directing light forward and preventing energy dissipation, while still allowing accessibility when opened as needed.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A light bar cover for covering a light bar is provided, which comprises a cover portion, hinges, cover handles, hook rings, and one or more hooks. The cover portion is configured for covering a front portion of the light bar. The hinges are installed between the cover portion and the light bar, so as to open and close the cover portion about the hinges. Each of the cover handles is disposed on an exterior surface of the cover portion. Each of the hook rings is disposed on an exterior surface of the light bar. The hooks are configured for holding each of the cover handles and a corresponding hook ring, so as to hold securely the cover portion in an open position or a close position.
