Headlamp Mounting Clip with Truncated Pyramid Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching headlights to vehicle front ends are costly and time-consuming due to the need for multiple fixing elements and screws, which increase material and financial expenses, while also requiring specialized tools for assembly and disassembly.
Innovation Solution
A device featuring a mounting housing with a quadrangular opening and a locking pin with lateral expansion surfaces and an upper safety clip, allowing for alignment and secure fixation of the headlight using a pre-assembly clip and truncated pyramid-shaped locking pin, eliminating the need for specialized tools and reducing material and financial costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fixing elements and screws are used to attach the headlight, then the attachment stability and alignment precision are improved, but the device complexity and material costs increase
Solution Approach 1:
The patent combines multiple fixing functions into a single integrated clip assembly that includes both positioning and securing features. The clip integrates the functions of alignment guides, retention elements, and mounting features into one component, eliminating the need for separate screws and multiple fixing elements while maintaining attachment stability.
Solution Approach 2:
The clip assembly serves multiple functions simultaneously: it provides alignment guidance during installation, secures the headlight in position, and enables tool-free attachment and detachment. This multi-functional design replaces several specialized components with a single universal fixing mechanism.
2Reliability
If multiple fixing elements and screws are used to attach the headlight, then the attachment stability is improved, but the assembly time and installation complexity increase
Solution Approach 1:
The clip is pre-assembled with the headlight holder during manufacturing, so that during vehicle assembly, only a single snap-in operation is required. The alignment guides are pre-positioned on the clip, eliminating the need for on-site alignment adjustments and reducing assembly time while maintaining secure attachment.
Solution Approach 2:
The clip incorporates elastic retention elements that provide flexible, tool-free attachment. The elastic properties allow the clip to deform during installation and then lock into place, enabling quick assembly without requiring threaded fasteners or complex tightening operations, thereby significantly reducing assembly time.
3Manufacturing precision
If resilient tongues are installed in the guide slots to compensate for play, then the alignment precision is improved, but the material costs and financial expenses increase
Solution Approach 1:
Instead of adding resilient tongues throughout the guide slots, the patent implements precision-machined guide surfaces with optimized geometric profiles at critical locations. The guide elements feature tapered surfaces and complementary shapes that naturally self-align components, achieving high alignment precision through localized geometric design rather than distributed resilient elements.
Solution Approach 2:
The guide elements and locking surfaces are designed with asymmetric geometries that provide directional guidance and automatic self-alignment during assembly. The asymmetric profiles ensure precise positioning through geometric constraints alone, eliminating the need for additional resilient compensation elements and reducing material costs.
