Vehicle Equipment Deflector Layout for Headlamp Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorption systems in motor vehicles, particularly in the front area, are not adapted to the reduced overhangs of newer vehicles, such as electric vehicles, leading to inadequate protection for expensive equipment during impacts.
Innovation Solution
A protective arrangement featuring a deflector made from stamped sheet metal, strategically positioned between the light device and equipment, which deflects the light device's trajectory during an impact, using a breakable tab to guide the light device away from critical paths and a thicker, more resistant deflector to absorb shocks, thereby reducing damage to the equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing shock absorption systems are used in the front of the vehicle, then equipment protection is provided, but the system occupies a significant volume that is incompatible with reduced overhang dimensions
Solution Approach 1:
The patent extracts the essential protective function from traditional bulk shock absorption systems and implements it through a localized deflector component positioned between the lighting device and equipment. This deflector is made from stamped sheet metal with thickness ≥1.5mm, providing protection without requiring the large volume of conventional systems.
Solution Approach 2:
Instead of using a uniform shock absorption system throughout, the patent applies protective measures locally where needed - specifically positioning a deflector between the lighting device and equipment. This localized approach provides targeted protection while minimizing overall system volume to fit reduced overhang dimensions.
2Reliability
If the deflector thickness is increased to improve shock absorption, then equipment protection is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent optimizes the deflector thickness parameter within a specific range (≥1.5mm, preferably ≥2mm) to achieve adequate shock absorption without excessive complexity. This parameter optimization balances protective capability with manufacturability, avoiding both insufficient protection and overly complex thick structures.
Solution Approach 2:
The patent specifies using stamped sheet metal for the deflector, which combines the strength and shock absorption properties of metal with the manufacturing efficiency of stamping processes. This material selection achieves both adequate protection and ease of manufacture.
3Force
If the deflector is made thicker and more resistant, then impact force absorption is improved, but the weight of the component increases
Solution Approach 1:
The patent specifies an optimal thickness range for the deflector (≥1.5mm, preferably ≥2mm) that provides adequate impact force absorption without excessive weight. This parameter optimization ensures the deflector is thick enough to deflect the lighting device during impact but not so thick as to create unnecessary weight.
4Reliability
If the mounting strength of the deflector is increased beyond the light device mounting tab strength, then equipment protection is improved, but the device complexity increases
Solution Approach 1:
The patent designs the mounting system so that the deflector is pre-attached to the equipment mounting bracket with strength exceeding the light device mounting tab strength. This preliminary attachment ensures that during impact, the deflector remains securely in place while the lighter mounting tab may fail, allowing the deflector to continue providing protection without complex additional mounting mechanisms.
Applied Scientific Principles
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 solution effectively reduces the risk of equipment damage by altering the light device's trajectory and distributing impact forces, minimizing deformation and damage during frontal impacts, while maintaining a compact design suitable for vehicles with reduced overhangs.
Implementation Method 1
the deflector includes at least one surface capable of deflecting the trajectory of the lighting device over the equipment in the event of an impact causing the lighting device to move a second distance toward the equipment
Implementation Method 2
using a breakable tab to guide the light device away from critical paths and a thicker, more resistant deflector to absorb shocks
