Resilient Stabilisation Arms for Headlamp Optoelectronic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle headlamp lighting devices have increased structural complexity and costs due to the use of separate spring elements to stabilize optoelectronic components, which complicates the fastening process.
Innovation Solution
A lighting device design that incorporates a stabilisation element with resilient arms that counteract the pressure of a cooling element, eliminating the need for separate spring elements by integrating the stabilisation arms as part of the stabilisation element, which is connected to the cooling element via a fastening element, providing both stability and resilience to the optoelectronic component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate spring elements are used to stabilize the optoelectronic component, then the stability and resilience are improved, but the structural complexity and costs increase
Solution Approach 1:
The patent combines the stabilisation function and resilience function into a single integrated stabilisation element. This element includes an opening for enclosing the optoelectronic component and resilient stabilisation arms that extend from the opening to provide both positional stability and shock absorption, eliminating the need for separate spring elements and reducing structural complexity
2Reliability
If separate spring elements are used to stabilize the optoelectronic component, then the resilience is improved, but the manufacturing costs increase
Solution Approach 1:
The stabilisation element integrates multiple functions (enclosure, stabilization, and resilience) into a single component that can be manufactured as one piece. The resilient stabilisation arms are formed as integral parts of the stabilisation element, reducing the number of parts that need to be manufactured, assembled, and inventoried, thereby lowering manufacturing costs
3Stress or pressure
If separate spring elements are used between the cooling element and optoelectronic component, then the pressure compensation is improved, but the number of components increases
Solution Approach 1:
The stabilisation element merges the pressure compensation function with the structural support function. The resilient stabilisation arms are configured to be pressed against the optoelectronic component by the cooling element, providing automatic pressure compensation while maintaining structural support, all within a single integrated component rather than requiring separate spring elements
