Resin Storage Case Transparent Lid for Label Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic tape cartridge storage cases with complex rib structures are difficult to read from the outside due to their design, requiring cardboard boxes for product identification labels, making it inconvenient to search for specific cartridges.
Innovation Solution
A resin-based storage case with a transparent transmission part that contacts the label area, allowing visual recognition and reading of labels from the outside, eliminating the need for cardboard boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If complicated rib shapes are formed in the storage case for packaging, then the storage case can be enclosed in cardboard boxes and delivered, but it becomes difficult to read bar codes and character strings from the outside
Solution Approach 1:
The lid member is divided into a transparent transmission part and a support part with different functions. The transmission part provides optical transparency for label reading, while the support part provides structural support for stacking. This segmentation allows each part to optimize its specific function without compromising the other.
Solution Approach 2:
The lid member has non-uniform optical properties: the transmission part is transparent to allow label reading, while other portions can be opaque for structural integrity and stacking support. This local differentiation of material properties resolves the contradiction between readability and structural requirements.
2Manufacturing precision
If the storage case is enclosed in cardboard boxes, then product identification information labels can be affixed, but the work of searching for desired recording tape cartridges becomes very complicated and inconvenient
Solution Approach 1:
The invention extracts and eliminates the cardboard box packaging layer, allowing the storage case itself to serve as the packaging and display medium. The transparent lid member replaces the need for cardboard boxes, enabling direct visual access to labels without opening additional packaging layers.
Solution Approach 2:
The storage case lid member provides its own label transmission function through the transparent part, eliminating the need for separate cardboard box packaging. The case structure itself serves the dual purpose of containment and label display, reducing operational steps for users.
3Difficulty of detecting and measuring
If a transparent flat surface is formed closer to the bottom plate side than the support part, then label areas can be visually recognized from the outside, but the structural support for stacked case bodies may be compromised
Solution Approach 1:
The lid member is segmented into a transparent transmission part for label viewing and a separate support part for structural stacking. This segmentation allows the transmission part to be positioned for optimal label visibility while the support part maintains structural integrity for stacking multiple cases.
Solution Approach 2:
Different portions of the lid member have different optical and mechanical properties. The transmission part is transparent and positioned to contact label areas, while the support part has enhanced structural properties for stacking. This local differentiation resolves the contradiction between visibility and strength requirements.
