Vehicle Light Bar Mounting Foot with Rotatable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting systems for light bars on emergency vehicles do not provide a secure and aesthetically pleasing method for mounting and securing light assemblies, which can affect the visibility and durability of the light bar.
Innovation Solution
A mounting foot system with platforms and connecting plates that securely hold light assemblies, allowing for rotatable light enclosures and slidably received bases, along with a connecting plate for securing the light bar and mounting bracket, ensuring strong and rigid attachment to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light assemblies are mounted on the mounting foot, then the signaling capability is enhanced, but the structural complexity increases
Solution Approach 1:
The light assembly base is nested within a recess formed in the platform of the mounting foot. This recess provides a designated space that accommodates the base, allowing the light assembly to be integrated into the mounting foot structure without requiring additional external support structures, thereby enhancing signaling capability while managing structural complexity.
Solution Approach 2:
The mounting foot is divided into distinct functional components: a body portion for mounting to the vehicle, a platform extending from the body, and a recess formed in the platform. This segmentation allows each component to perform its specific function independently while contributing to the overall system capability.
2Ease of repair
If the light assembly base is slidably received in the platform, then the ease of replacement is improved, but the structural stability may be compromised
Solution Approach 1:
The recess in the platform provides a nested receptacle for the light assembly base. This nested structure naturally retains the base in place through the confined space while still allowing horizontal sliding motion, thus maintaining structural stability without preventing easy replacement.
Solution Approach 2:
The recess acts as an intermediary structure between the platform and the light assembly base. It provides a transition zone that facilitates easy insertion and removal of the base while maintaining a stable, secure fit during operation.
3Adaptability or versatility
If the light enclosure is rotatably connected to the base, then the adaptability of light direction is improved, but the mechanical complexity increases
Solution Approach 1:
The light enclosure is rotatably connected to the base, transforming it from a static component to a dynamic one. This rotational capability allows the light direction to be adjusted as needed while maintaining a relatively simple mechanical connection, achieving adaptability with minimal added complexity.
4Strength
If the mounting foot is secured to the roof with the connecting plate, then the attachment strength is improved, but the device complexity increases
Solution Approach 1:
The connecting plate is integrated with the mounting foot body, merging the mounting function into the primary structure. This consolidation provides strong attachment capability while avoiding the need for separate, additional mounting components, thus improving attachment strength without proportionally increasing device complexity.

AI summary
A mounting foot for mounting a light bar on a roof of a vehicle includes at least one platform. The platform includes a recess for slidably receiving a base of a light assembly to mount the light assembly on the platform. The light assembly has a base fixedly secured to the platform and a light enclosure rotatably connected to the base of the light assembly.
