Rear Paneling with U-Shaped Profiles for Reversing Camera Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reversing systems for road vehicles lack adequate protection for the rear paneling, including the reversing camera and license-plate lamps, from impact damage, which can lead to equipment failure and increased accident risk during reversing maneuvers.
Innovation Solution
A rear paneling design featuring U-shaped extruded aluminum alloy profiles and a steel doubler plate to distribute mechanical loads, along with glass fiber-reinforced polyamide runners that elevate the reversing camera and provide ribbed protection, secured with screws aligned with the vehicle's roll and yaw axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rear paneling without additional protection structures is used, then the device complexity is low and ease of manufacture is high, but the reversing camera and license-plate lamps are vulnerable to impact damage
Solution Approach 1:
The patent applies preliminary action by pre-installing protection runners made of glass fiber-reinforced polyamide on the rear paneling before the reversing camera and license-plate lamps are exposed. These runners are positioned to elevate and shield the camera and lamps from direct impact with solid objects, distributing impact forces away from sensitive components. The protection structure is integrated into the paneling design itself, creating a first line of defense that activates before any potential damage occurs.
Solution Approach 2:
The patent employs composite materials by using glass fiber-reinforced polyamide for the protection runners. This composite material combines the high impact resistance and structural strength of glass fibers with the durability and weather resistance of polyamide. The composite structure provides superior protection compared to conventional materials, enabling the runners to absorb and distribute impact forces effectively while maintaining structural integrity under various environmental conditions.
2Reliability
If foam inserts are used for impact protection as proposed in DE 10 2015 115606 A1, then some protection is provided, but the protection is insufficient for adequately protecting the reversing camera and license-plate lamps from solid object impacts
Solution Approach 1:
The patent applies parameter changes by transitioning from soft foam inserts to rigid protection runners made of glass fiber-reinforced polyamide. This material parameter change fundamentally alters the protection mechanism: instead of deforming to absorb impact, the runners maintain structural integrity and distribute impact forces across a larger area. The runners' elevated position and ribbed structure create geometric parameters that further enhance protection by increasing the distance between impacting objects and sensitive components.
Solution Approach 2:
The patent implements beforehand cushioning by pre-positioning the protection runners to create a physical barrier between potential impacting objects and the reversing camera and license-plate lamps. The runners are designed with sufficient length and elevation to cushion against impacts from various angles and object sizes. This prior cushioning structure is integrated into the paneling design, ensuring protection is already in place before any accident occurs, rather than relying on reactive measures.

AI summary
A rear paneling for a road vehicle has U-shaped extruded profiles (11, 12) mounted on the crossmember of the road vehicle and runners fit next to the reversing camera (20) for raising the reversing camera (20) over a solid body colliding with the rear paneling (10).
