Solution Overview

Problem

Carbide tipped drill bits require effective protection during storage and display to prevent damage to their cutting tips, which existing packaging solutions often fail to adequately address.

Innovation Solution

A packaging assembly comprising a front clip and a back clip, where the back clip is secured to the front clip using ultrasonic welding, screws, rivets, or adhesive, with customizable channels and ridges to accommodate various drill bit sizes, ensuring secure and protective storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If drill bits are displayed without packaging protection, then visibility and accessibility are improved, but the carbide cutting tips are vulnerable to damage

Engineering Contradiction:

Improveprotection of carbide cutting tipsVSAvoidpackaging structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The packaging is divided into separate functional components: a front clip for display and a back clip for protection, connected by posts. This segmentation allows each component to be optimized for its specific function while providing comprehensive protection for the carbide cutting tips.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The drill bit is nested within the packaging assembly, held securely between the front and back clips. The posts with enlarged heads provide nested protection, with the melted plastic material filling gaps and providing additional protective layers around the vulnerable carbide tips.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If traditional packaging methods are used, then manufacturing simplicity is maintained, but the carbide tips are not adequately protected during storage and display

Engineering Contradiction:

Improveprotection effectivenessVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The posts are designed with variable parameters - specific dimensions, material properties, and geometric features (enlarged heads) that change during the manufacturing process through localized vibration and melting. This allows the same basic structure to provide enhanced protection while maintaining manufacturing simplicity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging utilizes phase transition of the plastic material through localized vibration-induced melting and subsequent cooling. This phase change enables the material to flow and conform to the drill bit shape during assembly, then solidify to provide rigid protection, enhancing reliability without significantly increasing manufacturing complexity.

Inventive Principle:

Principle #36Phase transitions

3Object-affected harmful factors

If protective packaging is implemented, then damage prevention is improved, but manufacturing costs may increase

Engineering Contradiction:

Improvedamage preventionVSAvoidmanufacturing cost

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The packaging assembly is designed as a universal solution that can accommodate various drill bit sizes and types through the adjustable post configuration and melted plastic adaptation. This multi-functionality reduces the need for multiple specialized packaging designs, thereby controlling manufacturing costs while providing comprehensive protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The packaging structure is designed to be self-adjusting through the localized vibration process that melts and redistributes the plastic material automatically during assembly. This self-service mechanism eliminates the need for complex adjustment mechanisms or multiple packaging variants, maintaining manufacturing simplicity while enhancing protection effectiveness.

Inventive Principle:

Principle #25Self-service
