Lamp Module Support Element for Precise Alignment Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lamp module assembly methods using pins and complementary shaped openings suffer from precision issues due to manufacturing imprecision, leading to relatively large alignment inaccuracies in assembled components.
Innovation Solution
A support element with complementary alignment members, comprising protrusions and gaps, ensures precise alignment by seating the protrusion on multiple points within the gap, thereby maintaining the relative position of the module components, even with manufacturing imprecision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pins and complementary shaped openings are used to align lamp module components, then assembly is simplified and components can be connected, but manufacturing imprecision causes alignment inaccuracies to accumulate across multiple component pairs
Solution Approach 1:
The patent merges multiple alignment functions into a single support element that simultaneously aligns multiple lamp module components. Instead of using separate pins for each component pair, one support element with multiple alignment members (protrusions and gaps) performs all alignment functions, eliminating cumulative errors from multiple separate alignment operations.
Solution Approach 2:
The support element acts as an intermediary component that mediates the alignment between multiple lamp module components. Rather than having components align directly with each other through pins and openings, the support element serves as a central reference that all components align to, preventing error accumulation.
2Stability of the object's composition
If multiple securing elements and recesses are provided on connected parts to secure them together, then connection stability is improved, but manufacturing imprecisions on the securing elements or recesses worsen the precision of the connection
Solution Approach 1:
The patent combines multiple securing functions into integrated alignment members (protrusions and gaps) on the support element. Instead of separate securing elements and recesses on each component, the support element has protrusions that fit into gaps on multiple components simultaneously, providing both stability and precision through a unified structure.
Solution Approach 2:
The patent changes the geometric parameters of the alignment members, specifically designing protrusions with specific shapes and gaps with complementary shapes. The gaps are designed with specific dimensions and orientations to receive the protrusions, creating precise angular and positional relationships that maintain both stability and precision.

AI summary
A support element for a lamp module adapted to precisely accommodate at least one part of the lamp module that comprises an alignment member of the part, wherein the support element comprises at least one alignment member of the element, wherein the alignment member of the part forms, with the alignment member of the element, a pair of specially shaped complementary alignment members adapted to define the relative position of the support element and the given part by tightly fitting a protrusion on one member of the pair into a gap on the other member of the same pair. Furthermore, the object of the invention is a lamp module comprising the support element and a method of lamp module assembly on such a support element.
