Radial Laser Disk Mounting for Thermal Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser disk mounting systems suffer from mechanical and thermal stresses that lead to non-spherical deformations, limiting the achievable laser power due to unsymmetrical support points, which can cause unstable laser operation and reduced power output.
Innovation Solution
A radial mounting system for laser disk modules, where the heat sink is clamped or soldered radially, providing symmetrical contact and minimizing non-spherical deformations by applying forces orthogonal to thermal forces, thus maintaining a stable spherical deformation and reducing micro-movements during thermal and mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a three-point support system is used to clamp the laser module, then the laser disk can be held in a defined position, but mechanical and thermal stresses cause non-spherical deformations that limit achievable laser power
Solution Approach 1:
The patent transitions from three-point support (discrete points in 3D space) to continuous radial clamping along the entire circumference of the heat sink. This dimensional change from point-contact to surface-contact distribution eliminates localized stress concentrations and achieves uniform spherical deformation of the laser disk, resolving the contradiction between positioning precision and laser power output.
Solution Approach 2:
The patent changes the distribution pattern of support forces from discrete three-point contact to continuous radial distribution. By modifying the spatial parameter of force application from localized to distributed, the system achieves uniform deformation while maintaining positioning accuracy, thereby enabling higher laser power output without sacrificing positioning precision.
2Stability of the object's composition
If support points are applied to the laser module, then the laser disk can be held stable, but unsymmetrical support points cause non-spherical deformations that reduce power output
Solution Approach 1:
The patent applies symmetry principles by distributing support forces uniformly around the entire circumference of the heat sink. This symmetric radial clamping configuration ensures that the laser disk deforms spherically rather than asymmetrically, maintaining optical quality while providing stable support. The symmetric distribution eliminates the unsymmetrical deformations that would otherwise reduce power output.
3Power
If radial clamping is applied to the heat sink, then non-spherical deformations are minimized and laser power is maintained, but the mounting system becomes more complex
Solution Approach 1:
The radial clamping mechanism serves multiple functions simultaneously: it provides uniform support forces around the heat sink circumference, maintains spherical deformation of the laser disk, ensures stable positioning, and dissipates thermal stresses evenly. This multi-functionality achieves high laser power output without requiring multiple separate components, thereby limiting the increase in device complexity.
