Solution Overview

Problem

Conventional screws lack decorative functionality while maintaining their primary purpose of fastening, leaving a gap in the market for aesthetically pleasing fastening solutions.

Innovation Solution

A decorative screw design featuring a head with an ornamental shape and a shaft that can be coupled with various tools, allowing for decorative arrangements on objects, such as wooden surfaces, by threading into the object and providing multiple tool wells for different driving options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional screws are used, then fastening functionality is achieved, but decorative functionality is lacking

Engineering Contradiction:

Improveaesthetic appearanceVSAvoiddecorative functionality

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The screw head is divided into multiple tool wells (first tool well, second tool well, third tool well) with different shapes, allowing different driving tools to be used. This segmentation enables the same screw to serve both fastening and decorative purposes by selecting appropriate tools for different aesthetic requirements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The screw head is designed with multiple tool wells that can accommodate different types of driving tools (e.g., flathead, Phillips, Allen wrench). This multi-functionality allows a single screw design to serve both functional fastening and various decorative applications, eliminating the need for separate decorative fasteners.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the head has an ornamental shape, then decorative functionality is improved, but tool access for fastening may be limited

Engineering Contradiction:

Improvedecorative functionalityVSAvoidtool access

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The head is segmented into multiple tool wells with different orientations and shapes. This segmentation ensures that at least one tool well remains accessible for fastening operations while other wells provide decorative value, resolving the conflict between ornamental shape and tool access.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple tool wells are positioned at different locations and orientations on the head surface. This spatial distribution in multiple dimensions ensures that tool access is maintained even when the head has an ornamental shape, as tools can approach from different angles.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple tool wells are added to the head, then versatility is improved, but device complexity increases

Engineering Contradiction:

Improvetool compatibilityVSAvoidhead structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple tool wells are merged into a single integrated head structure. Rather than adding separate components for different tool types, the design combines multiple tool receptacles into one unified head, achieving versatility without proportionally increasing overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)
