Burred Top Plate Openings for Cooling and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming devices face challenges in balancing cooling performance and structural strength, particularly with openings on the top plate, which can lead to reduced strength and increased noise due to insufficient cooling and wind noise generation.
Innovation Solution
The image forming device incorporates a top plate with openings processed by burring, specifically designed to enhance strength and reduce noise by optimizing the shape and placement of air suction holes, ensuring efficient cooling while maintaining durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If openings are provided on the top plate to improve cooling performance, then cooling performance is improved, but strength of the top plate is reduced
Solution Approach 1:
The patent applies burring processing to change the physical state of the opening edges, transforming them from sharp edges to rounded edges with protrusions. This parameter change in edge geometry strengthens the top plate structure around the openings while maintaining the cooling function, thus resolving the contradiction between cooling performance and structural strength.
2Temperature
If openings are provided on the top plate to improve cooling performance, then cooling performance is improved, but wind noise is generated
Solution Approach 1:
The burring processing changes the edge geometry parameter of the openings, creating rounded edges with protrusions that smooth airflow. This parameter change reduces turbulence and wind noise generation while preserving the cooling airflow function, thereby resolving the contradiction between cooling performance and noise reduction.
3Ease of manufacture
If conventional opening processing is used, then manufacturing is simple, but strength is reduced and noise is increased
Solution Approach 1:
The burring processing method uses a simple mechanical tool to change the edge parameters of openings, achieving both strength enhancement and noise reduction through a straightforward manufacturing process. This maintains ease of manufacture while improving strength and reducing noise, resolving the contradiction between manufacturing simplicity and performance requirements.
