Display Panel Packaging with EPS Box and EPP Stoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel packaging structures made of EPS often have inaccurately determined box sizes, leading to poor fixing and positioning capabilities, resulting in potential damage during transportation due to impact displacement between the array substrate and circuit board.
Innovation Solution
A display panel packaging structure with a box equipped with stoppers that abut against the display panel's side surfaces, providing improved fixing and positioning, and optionally featuring a strengthening plate for enhanced stability, which can be made from cost-effective materials like EPS with stoppers made of EPP or EPO for added protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the box is made of EPS material to reduce manufacturing cost, then the manufacturing cost is reduced, but the fixing and positioning capability is poor leading to potential damage during transportation
Solution Approach 1:
The packaging structure is divided into two functional segments: the box body made of cost-effective EPS material and the stoppers made of higher-cost EPP or EPO material. This segmentation allows each component to be optimized independently - the box for cost efficiency and the stoppers for protection - resolving the contradiction between manufacturing cost and reliability.
Solution Approach 2:
Different materials are applied to different parts of the packaging structure based on their specific functional requirements. The box body uses EPS for cost-effectiveness, while the stoppers use EPP or EPO for their superior shock-absorbing properties and precise positioning capability, achieving local optimization of both cost and reliability.
2Ease of manufacture
If the box size is made slightly larger than the display panel to accommodate manufacturing tolerances, then the manufacturing process is easier, but the fixing and positioning capability deteriorates causing impact displacement during transportation
Solution Approach 1:
The stoppers are pre-positioned within the box at predetermined locations before the display panel is placed inside. This preliminary positioning action ensures that when the panel is inserted, it is immediately constrained and positioned accurately, compensating for any dimensional variations in the box and achieving precise positioning without requiring tight manufacturing tolerances on the box itself.
3Reliability
If stoppers made of EPP or EPO material are added to improve protection, then the reliability is improved, but the manufacturing cost increases
