Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing element array pressing devices face challenges in ensuring even pressure distribution during the mounting process, leading to potential mounting malfunctions due to uneven pressure application on the elements.
Innovation Solution
The use of a press plate with a hard member having a higher surface flatness than the press plate, which applies pressure to the element array, along with a resilient member that deforms to enhance evenness, and water repelling layers to prevent adhesion and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a press plate is used to press the element array, then the elements can be mounted on the mounting substrate, but uneven pressure distribution occurs leading to mounting malfunctions
Solution Approach 1:
The press plate surface is modified by attaching hard members (such as glass plates or ceramic plates) with high surface flatness to specific pressing regions. This creates local areas of enhanced pressing quality, ensuring uniform pressure distribution across the element array while maintaining the overall press plate structure. The hard members compensate for surface irregularities and prevent uneven pressing that causes mounting malfunctions.
2Manufacturing precision
If a resilient layer with fluidity is placed between the press plate to press elements evenly, then pressure distribution improves, but mounting malfunctions still occur due to insufficient evenness
Solution Approach 1:
The pressing system uses a composite structure combining the resilient layer with hard members (glass plates or ceramic plates) having high surface flatness. The resilient layer provides fluidity and initial pressure distribution, while the hard members attached to its surface provide the necessary surface flatness and rigidity to ensure uniform pressure transmission. This composite approach achieves both even pressure distribution and reliable mounting by combining the advantages of both material types.
3Manufacturing precision
If the press plate surface flatness is increased, then pressure distribution improves, but the press plate structure becomes more complex
Solution Approach 1:
Instead of manufacturing the entire press plate with high surface flatness (which would increase complexity and cost), the solution segments the pressing surface by attaching hard members (glass plates or ceramic plates) only to the specific pressing regions that require high flatness. This segmentation approach achieves the necessary surface quality where needed while keeping the overall press plate structure simple and manageable.
