Transparent Luggage Shell Decorative Plate Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional luggage shell structures face limitations in pattern design due to thermoplastic molding and vacuum suction processes, which deform and lighten surface colors, and incur high costs for multiple design variations and complex assembly processes.
Innovation Solution
A flat and bendable decorative plate replaces the inner shell, allowing pattern designs on both flat and curved surfaces, and is assembled with a lining directly fixed to the plate, simplifying assembly and reducing costs by eliminating the need for complex molding and multiple shell production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If thermoplastic molding and vacuum suction are used to form the inner shell, then the shell structure is formed, but the pattern on the decorative surface is deformed and the surface color becomes lighter
Solution Approach 1:
The invention extracts the problematic inner shell structure and replaces it with a flat decorative plate. By removing the thermoplastic molding process entirely, the pattern printing and surface color quality are preserved without deformation, while only the necessary shell structure remains.
Solution Approach 2:
The invention replaces the expensive, complex thermoplastic molded inner shell with a simpler, more economical flat decorative plate that can be easily manufactured and replaced. This disposable-like approach to the decorative element reduces overall manufacturing complexity and cost.
2Adaptability or versatility
If multiple inner shells with different patterns are produced, then diverse pattern designs are achieved, but the production cost increases
Solution Approach 1:
The flat decorative plate serves as a universal base that can accommodate multiple different pattern designs through simple printing processes. Rather than creating entirely different shells for each pattern, the same plate structure is used universally with varied surface decorations, reducing production costs while maintaining design diversity.
Solution Approach 2:
The invention uses printing technology to create different patterns on identical flat decorative plate structures. This copying approach allows multiple design variations to be produced from a single mold, significantly reducing the cost compared to producing multiple different inner shells through thermoplastic molding.
3Ease of operation
If the glue strip is sewn to the lining and then installed to the outer shell, then the inner shell is fixed, but the assembly process becomes complex and troublesome
Solution Approach 1:
The invention extracts the problematic multi-step assembly process involving glue strips and complex sewing operations. By replacing the inner shell with a flat decorative plate that can be directly fixed to the lining, the assembly process is simplified to a single straightforward step, eliminating the troublesome intermediate steps.
Solution Approach 2:
The invention merges the functions of the inner shell and the decorative element into a single flat decorative plate that is directly attached to the lining. This consolidation eliminates the need for separate glue strip components and multiple assembly steps, reducing overall assembly complexity.

AI summary
A transparent shell structure for luggage and the like includes an outer shell, a decorative plate, a lining, and a plurality of corner protectors. The outer shell has an inner space with a frame. One side of the decorative plate is a patterned surface. Each of the four corners of the decorative plate has a notch, so that the four sides thereof are bent inside the inner space. The decorative plate is restricted within the outer shell. The lining is attached to the decorative plate and disposed in the inner space of the outer shell with the decorative plate, connecting to the frame by the sides. The corner protectors are connected to the four corners of the outer shell.
