Solution Overview

Problem

Existing case manufacturing methods fail to produce durable, waterproof, dust-proof, and secure cases that are easy to assemble and reuse, while also being affordable and adaptable for various sizes and shapes.

Innovation Solution

The method involves processing sheet-like materials into components with adhesive coatings, allowing them to be easily assembled into cases with storage spaces using double-sided tape, which can be used to create cases of different sizes and shapes without visible fasteners, and can be disassembled for reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional case manufacturing methods are used, then cases can be produced, but they lack durability, waterproofing, dust-proofing, and security features

Engineering Contradiction:
Improvecase durability and protectionVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The case is divided into multiple separate components (first component, second component, third component) that can be manufactured independently and then assembled together. This segmentation allows each component to be optimized for specific functions (protection, sealing, accessibility) while simplifying the manufacturing process for each individual part.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case components are made from composite materials that combine different properties - the sheet-like material provides structural integrity and durability, while the adhesive coating provides bonding and sealing capabilities. This composite approach enables the case to achieve waterproofing and dust-proofing without complex manufacturing.

Inventive Principle:
Principle #40Composite materials

2Reliability

If cases are made secure and waterproof, then protection is improved, but assembly and disassembly become difficult

Engineering Contradiction:
Improvewaterproof and dust-proof protectionVSAvoidassembly and disassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Traditional mechanical fastening systems (screws, clips, latches) are replaced with an adhesive bonding system. The adhesive coating on the components provides strong bonding for waterproof and dust-proof protection, while also allowing for relatively easy disassembly and reuse compared to permanent mechanical fastening methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If cases are designed for specific sizes and shapes, then functionality is improved, but adaptability to different devices is reduced

Engineering Contradiction:
Improvecase functionality for specific devicesVSAvoidcase size and shape flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The case design allows for dynamic configuration where components can be arranged in different orientations and combinations. The sheet-like components can be cut and shaped to accommodate different device sizes and forms, enabling the same basic component set to serve multiple device types and configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The case components are designed as universal elements that can be used across different device types. The sheet-like material components can be configured for various sizes and shapes, and the same adhesive bonding mechanism works for different material combinations, making the case system adaptable to diverse electronic devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If cases include visible fasteners for security, then opening control is improved, but aesthetic quality deteriorates

Engineering Contradiction:
Improvecontrolled opening mechanismVSAvoidaesthetic quality and visible fasteners
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

Visible mechanical fasteners (screws, clips, latches) are replaced with an adhesive bonding system that provides secure attachment without visible external fastening elements. The adhesive provides the necessary bonding strength for security while maintaining a clean, aesthetic appearance, and controlled opening is achieved through the adhesive bonding mechanism rather than visible fasteners.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
