Modular Pen Case with Detachable Cover for Adjustable Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pen cases lack modularity, allowing only one fixed position for the cover, which restricts the ability to adjust the angle of presentation on inclined surfaces, making it difficult to easily retrieve pens.
Innovation Solution
A detachable cover with complementary fastening means, such as parallel slits and pawns, allows the cover to be fixed to the envelope in various positions, enabling adjustable inclination and modular attachment of multiple cases for increased versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cover is fixed in one position on the envelope, then the case structure is simple, but the adaptability to different surfaces and angles is poor
Solution Approach 1:
The case is divided into two separable parts: the envelope and the cover. The cover can be detached from the envelope and reattached at different positions along the envelope's edges, enabling adjustment of the envelope's inclination angle on various surfaces while keeping the overall structure simple
Solution Approach 2:
The cover transitions from a fixed position to a dynamically adjustable position. By allowing the cover to be detached and reattached at different locations on the envelope, the system gains adaptability to different surfaces and angles without requiring complex mechanical adjustment mechanisms
2Ease of operation
If the cover is rigidly attached to the envelope, then the case is stable during transport, but the ease of operation for accessing pens is reduced
Solution Approach 1:
The cover is designed to be detachable and reattachable at different positions. During transport, the cover can be attached to provide stability, and during use, it can be detached or repositioned to allow easy access to pens, thus balancing stability and ease of operation
Solution Approach 2:
The cover can be temporarily detached from the envelope when pen access is needed, and then reattached when protection and stability are required. This reversible attachment mechanism allows the user to switch between operational modes as needed
3Ease of manufacture
If the envelope is made flexible, then the case can be compressed for storage, but the manufacturing precision and structural integrity are reduced
Solution Approach 1:
The case combines rigid components (envelope and cover made of rigid material) with a simple attachment mechanism. This composite approach maintains structural integrity and manufacturing precision while avoiding the need for flexible materials, as the modularity allows compression without compromising the rigid structure
