Solution Overview
Problem
Current packaging technologies with vertical reinforcements are difficult to mechanize, require complex formation, and lack efficient, rapid, and automatic methods for fitting reduced-dimensional reinforcements easily and asymmetrically, especially for heavy products requiring compression resistance and lateral access.
Innovation Solution
A method and device for fitting cardboard or corrugated cardboard reinforcements using a longitudinal structure with a specific form to compress and shape blanks, forming horizontal edges, and gluing them onto packaging cutouts to create strong, asymmetrical packaging with hollow struts, allowing for rapid and automatic formation of reinforcements at over 30 strokes per minute.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional reinforcement methods are used to improve compression resistance, then packaging strength is improved, but the process becomes difficult to mechanize and requires complex formation
Solution Approach 1:
The reinforcement is divided into separate modular elements that can be individually handled, formed, and applied to the packaging. This segmentation allows each reinforcement element to be independently manufactured using standardized processes, enabling mechanization while maintaining compression resistance.
Solution Approach 2:
The reinforcement elements are pre-formed with their final three-dimensional shape and gluing surfaces before being applied to the packaging. This preliminary formation allows complex geometries to be created using automated forming processes, eliminating the need for complex on-site formation mechanisms.
2Strength
If complex reinforcement formation processes are used to achieve vertical support, then packaging strength is improved, but production speed decreases
Solution Approach 1:
The reinforcement elements are designed to be self-forming through compression between the longitudinal structure and template, eliminating the need for complex forming mechanisms. The material itself provides the structural support through its compressed geometry, allowing rapid production while maintaining vertical support capability.
3Strength
If traditional reinforcement fitting methods are used to improve compression resistance, then packaging strength is improved, but the process becomes complicated and time-consuming
Solution Approach 1:
The manual or complex mechanical fitting processes are replaced with automated application mechanisms that position and secure reinforcement elements rapidly. The gluing process is streamlined to allow quick bonding of pre-formed elements, reducing fitting time while maintaining the compression-resistant structure.
4Ease of manufacture
If reduced-dimensional reinforcements are used to simplify the process, then ease of manufacture is improved, but the ability to provide adequate support is reduced
Solution Approach 1:
The reinforcement elements achieve adequate support capability through optimization of their dimensional parameters and geometric configuration. By carefully controlling the compression ratio, cross-sectional geometry, and material properties, the reduced-dimensional elements provide sufficient vertical support while maintaining ease of manufacture through standardized forming processes.
