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

VSEngineering 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

Engineering Contradiction:
Improveadaptability to different surfaces and anglesVSAvoidcase structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improveease of pen retrievalVSAvoidcase stability during transport
Core Design Contradiction:
Ease of operationVSReliability

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #34Discarding and recovering

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

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

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

Inventive Principle:
Principle #40Composite materials
