Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass roving packages face issues with shifting and collapse during transportation due to external forces, and the use of cartons as outer wraps is labor-intensive and costly.
Innovation Solution
A glass roving package configuration that includes a displacement prevention sheet interposed between groups of glass rovings, which provides physical integrity and prevents shifting, using a foamed resin sheet to cushion the glass rovings and reduce impact forces, and communication holes for uniform heat transfer and moisture discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a carton is used as the outer wrap of the glass roving package, then shifting and collapse during transportation are prevented, but packaging time and labor increase significantly
Solution Approach 1:
The invention extracts the essential function of the carton (preventing shifting and collapse) and implements it through a simpler structure: a base board with positioning protrusions and recesses that directly prevent package displacement without requiring a full carton enclosure. This eliminates the time-consuming carton assembly and disassembly processes.
Solution Approach 2:
The invention replaces the durable but complex carton with a simpler, lighter base board structure that achieves the same protective function. The base board with its positioning features provides sufficient stability during transportation without the need for a full carton, reducing both packaging time and material costs.
2Reliability
If a carton is used as the outer wrap, then physical integrity is improved, but the cost of the glass roving package increases
Solution Approach 1:
The invention replaces the expensive carton with a cheaper base board structure that provides sufficient protection. The base board with positioning features achieves the necessary physical integrity at lower material and manufacturing costs, making the overall package more cost-effective.
Solution Approach 2:
The invention extracts only the essential protective function from the carton (preventing shifting and collapse) and implements it through a simpler, cheaper base board with positioning protrusions and recesses. This eliminates unnecessary carton materials and assembly steps, reducing overall package cost.
3Reliability
If plate-like objects are used between wrapped units, then physical integrity is improved, but wrapped units slide under external force causing shifting
Solution Approach 1:
The invention uses asymmetric positioning protrusions and corresponding recesses between the base board and wrapped units. This asymmetric interlocking structure prevents sliding in all directions under external forces, overcoming the limitation of symmetric plate-like objects that allow sliding.
Solution Approach 2:
The positioning protrusions and recesses act as intermediary mechanical features that actively prevent sliding between wrapped units. These positioning features mediate the interaction between the base board and wrapped units, providing positive mechanical interference that resists sliding under external forces during transportation.

Function Achieved in This Case
The solution effectively prevents shifting and collapse during transportation, reduces packaging and unpacking time and costs, and ensures reliable physical integrity and thermal treatment uniformity.
Implementation Method 1
a foamed resin sheet to cushion the glass rovings and reduce impact forces
Implementation Method 2
the displacement prevention sheet interposed between the upper and lower groups of glass rovings can prevent the upper group of glass rovings from being displaced with respect to the lower group of glass rovings
