Resin Storage Case with Transparent Lid Windows for Label Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing magnetic tape cartridge storage cases with complex rib shapes make it difficult to read bar codes or character strings on individual identification labels from the outside, requiring the storage case to be opened to search for specific cartridges, which is inconvenient.
Innovation Solution
A storage case design with a resin case body and lid member featuring a bottom rib and top rib structure, respectively, and transparent transmission parts on the lid member to allow external visual recognition of label areas, enabling bar code reading and character string visibility without opening the case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complicated rib shapes are formed in storage cases for structural integrity and packaging, then product strength and packaging efficiency are improved, but the ability to visually recognize label areas from the outside deteriorates
Solution Approach 1:
The lid member is segmented into different functional areas: transparent transmission parts for label visibility and rib structures for structural strength. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
The lid member has non-uniform local properties: transparent transmission parts are made transparent for label viewing, while rib structures maintain opacity for structural support. This local differentiation resolves the contradiction between visibility and strength requirements.
2Reliability
If storage cases are enclosed in cardboard boxes for delivery, then product protection during transport is improved, but the complexity of packaging and delivery process increases
Solution Approach 1:
The storage case material parameters are optimized to achieve sufficient strength and protection without requiring additional cardboard boxing. The resin material and rib结构设计 provide adequate transport protection, eliminating the need for outer cardboard boxes.
3Measurement precision
If the storage case is opened to search for specific recording tape cartridges, then accurate identification is achieved, but the time and convenience of operation deteriorates
Solution Approach 1:
The transparent transmission parts act as an intermediary that allows optical penetration from the outside environment to the label areas inside the storage case. This enables label reading without physical opening of the case, maintaining identification accuracy while improving operational convenience.
4Difficulty of detecting and measuring
If transmission parts are made transparent for label visibility, then label area visibility from outside is improved, but the structural strength and sealing performance may deteriorate
Solution Approach 1:
The transparent transmission parts and rib structures are merged into a single integrated lid member. This combination allows the lid to simultaneously provide structural strength through ribs and label visibility through transparent areas, without requiring separate components.

AI summary
A recording tape cartridge storage case includes a case body made of resin having a bottom plate that is rectangular in a bottom view and a peripheral wall erected from a peripheral edge of the bottom plate, a plurality of recording tape cartridges being stored in at least two rows with label areas thereof directed upward, respectively, and a bottom rib interposed between mutually adjacent side surfaces of the recording tape cartridges that form the rows being formed on the bottom plate; and a lid member made of resin that is attached to an upper end of the peripheral wall, seals the case body, and has a top rib interposed between the side surfaces, transmission parts that are transparent flat surfaces being formed in portions that face the label areas on both sides of the top rib.
