Motor Vehicle Light Device Pivot Link Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing light device for motor vehicles faces challenges with smaller light modules, where screws and capsules become too large and prone to breaking, making it difficult to maintain proper positioning and stability, especially when multiple modules are used.
Innovation Solution
A light device with a pivot link featuring an elastically deformable element allows for pivoting of the light module about an axis on the support, using a setting means to adjust and a constraint means to hold the module in position, eliminating the need for capsules and absorbing vibrations to prevent breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and capsules are used to position light modules on the support, then the positioning function is achieved, but the screws and capsules become too large and prone to breaking when light modules are reduced in size
Solution Approach 1:
The patent removes the capsule component entirely from the positioning system. Instead of using a capsule with a screw, the invention uses a pivot link with an elastically deformable element that integrates the positioning and securing functions into a single component, eliminating the need for separate capsules and screws.
Solution Approach 2:
The patent combines the positioning screw and the securing capsule into a single integrated pivot link assembly. The pivot link incorporates both the adjustability function (through the threaded rod) and the securing function (through the constraint means), simplifying the overall structure and reducing the size of individual components.
2Adaptability or versatility
If multiple light modules are used to create a segmented light beam, then the lighting coverage is improved, but the positioning and stability of each module becomes more difficult to maintain
Solution Approach 1:
The pivot link with elastically deformable element provides self-adjusting positioning for each light module. The elastic element automatically absorbs vibrations and maintains stable positioning without requiring external adjustment mechanisms for each module, making the system easier to operate with multiple modules.
Solution Approach 2:
The elastically deformable element in the pivot link provides beforehand cushioning against vibrations and position shifts. This elastic cushioning prevents the light modules from becoming misaligned or unstable during operation, maintaining positioning accuracy without requiring additional stabilization components for each module.
3Device complexity
If the capsule size is reduced to match smaller light modules, then the component size compatibility is improved, but the capsule risks breaking
Solution Approach 1:
The patent eliminates the capsule component entirely, replacing it with a pivot link that integrates both positioning and securing functions. This removes the structural weakness of small capsules while maintaining the necessary securing capability through the constraint means built into the pivot link.
Solution Approach 2:
The pivot link uses composite construction with an elastically deformable element (such as rubber or polymer material) combined with rigid components. This composite structure provides both the flexibility needed for small-scale applications and the strength required to prevent breaking, overcoming the limitations of scaled-down capsule designs.

Function Achieved in This Case
This solution simplifies the positioning of light modules, allows for independent setting of each module, and provides stability and vibration absorption, enabling effective alignment and operation of multiple light segments in a segmented light beam.
Implementation Method 1
The constraint means is adapted to absorb the vibrations at the pivot link level and prevents the latter from breaking
Implementation Method 2
the elastically deformable element simplifies the positioning of the light device at the pivot link level
