Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing optical elements fail to provide adequate protection against damage and contamination, as they either offer insufficient fixation leading to abrasion during transportation or rough protection that can cause damage.
Innovation Solution
An optical element storage device with an elastic internal fixation type structure, featuring a base with a groove and boss for secure placement, a cover body unit with a pressing block and grooves for rotary internal fixation, and elastic members for shock absorption, ensuring maximum protection and stability during storage and transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple glass cover is used to protect the optical element, then the protection device is simple in structure, but the optical element shakes during transportation and collides with the glass cover causing abrasion
Solution Approach 1:
The storage device is divided into multiple functional components: a base with positioning grooves and bosses, a cover body unit with a pressing block, and an elastic member. This segmentation allows each component to perform its specific function - the base provides positioning, the pressing block provides fixation, and the elastic member provides shock absorption - thereby solving the contradiction between structural simplicity and protection reliability.
Solution Approach 2:
The elastic member is pre-installed between the pressing block and the base to provide cushioning before any collision occurs. When the optical element shifts during transportation, the elastic member absorbs the impact energy beforehand, preventing direct collision between the optical element and the hard surfaces, thus resolving the contradiction between simple structure and reliable protection.
2Reliability
If the optical element is fixed tightly to prevent shaking, then protection reliability improves, but the structure becomes more complex
Solution Approach 1:
The pressing block automatically adjusts its position based on the optical element's location. When the cover body unit is closed, the pressing block is pressed down by the cover and automatically contacts the optical element, applying fixation force without requiring external adjustment mechanisms. This self-service approach achieves reliable fixation while maintaining structural simplicity.
Solution Approach 2:
The pressing block is designed to be movable rather than fixed, allowing it to dynamically adapt to the optical element's position. The elastic member enables the pressing block to move vertically, providing flexible fixation that accommodates minor position variations while maintaining consistent contact pressure, thus achieving reliable protection without complex adjustment mechanisms.
3Device complexity
If rough protection packaging is used, then device complexity is low, but the optical element surface is easily damaged and contaminated
Solution Approach 1:
The base features localized soft treatment at critical contact points - the grooves and bosses are designed with smooth, rounded surfaces that locally provide gentle contact with the optical element. This local quality approach ensures that the areas where the optical element contacts the packaging have protective, non-abrasive surfaces, while the rest of the structure remains simple and rigid for overall stability.
