Lampshade Clamping Block Segmentation for Mold Print Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of large slide blocks in lampshade production results in mold prints on the inner surface, affecting the beauty and light transmission of the lampshade, while also increasing manufacturing costs and reducing the reliability and service life due to high contact areas and slow production speeds.
Innovation Solution
The design incorporates stop blocks and clamping blocks arranged on the lampshade wall and platform surface, eliminating the need for a large slide block, which improves light transmission, reduces production costs, and enhances reliability and service life by using smaller, faster-moving components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a large slide block is used to produce clamping blocks on the inner wall of the lampshade bottom, then the clamping blocks can be formed to install the electrical board, but mold prints are generated on the inner surface affecting the beauty and light transmission
Solution Approach 1:
The invention divides the single large slide block into multiple smaller slide blocks (first slide block and second slide block). Each small slide block forms one or more clamping blocks independently. This segmentation eliminates the need for a large contact area, preventing mold prints while still achieving the required clamping block formation for electrical board installation.
2Ease of manufacture
If a large slide block is used, then clamping blocks can be produced, but the production speed is slow and efficiency is low
Solution Approach 1:
The large slide block is divided into multiple smaller slide blocks that can move and operate independently or in parallel. This segmentation reduces the mass and inertia of each sliding component, enabling faster movement and injection cycles, thereby increasing production speed and efficiency while maintaining the capability to form all necessary clamping blocks.
3Ease of manufacture
If a large slide block is used, then clamping blocks can be produced, but the manufacturing cost is high due to large volume
Solution Approach 1:
The single large-volume slide block is divided into multiple smaller-volume slide blocks. Each small slide block only needs to cover the area required for its specific clamping block(s), significantly reducing the total material consumption and manufacturing cost while maintaining the functional capability to produce all necessary clamping blocks.
4Ease of manufacture
If a large slide block is used, then clamping blocks can be produced, but problems are easy to occur in movement process due to large contact area, reducing reliability and service life
Solution Approach 1:
The large slide block is divided into multiple smaller slide blocks with reduced contact areas. Smaller contact areas experience less friction and wear during movement, reducing the frequency of problems such as sticking or damage. This segmentation improves the reliability and extends the service life of the slide blocks while maintaining the capability to form all required clamping blocks.
