Solution Overview

Problem

Existing drill dust receptacles have complex designs and high production costs due to intricate cuts and the need for auxiliary joining means like glue, making them cumbersome to assemble and expensive to produce.

Innovation Solution

A drill dust receptacle made from a foldable sheet material with intersecting fold lines that allows for easy assembly and collapse into a flat shape, eliminating the need for additional joining means and reducing production costs, while also providing a seamless design that can be easily stored.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If auxiliary joining means such as glue are used to assemble the receptacle, then the structural integrity is improved, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The receptacle structure is designed to self-assemble through its own geometry. The side sections are configured to interlock with the front and back panels through folding along predetermined fold lines, eliminating the need for external joining means like glue. The structure serves its own assembly function through the mechanical interlocking of its components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The receptacle is divided into distinct foldable sections (front panel, back panel, and side sections) that can be independently formed and then assembled through folding. This segmentation allows each section to be optimized for its function while simplifying the overall assembly process through the foldable connection mechanism.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the receptacle is made from a complex blank design with multiple cuts and glue tabs, then the structural stability is improved, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of manufacture
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The invention changes the fundamental assembly parameter from chemical bonding (glue) to mechanical folding. The blank design uses fold lines instead of cut lines and glue tabs, transforming the assembly process into a simple folding operation that maintains structural stability while dramatically improving ease of manufacture.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The receptacle is designed as a disposable product with a simple blank that can be quickly assembled and then discarded after use. The foldable design without glue or complex joining means enables rapid assembly and disposal, suitable for single-use drill dust collection applications.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the receptacle is made from a foldable sheet material with fold lines, then the ease of assembly is improved, but the structural strength deteriorates

Engineering Contradiction:
Improveease of assemblyVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The receptacle transitions from a flat 2D blank to a 3D structure through dynamic folding along predetermined fold lines. The foldable sections are designed to interlock mechanically, providing structural strength during both assembly and use while maintaining ease of assembly through the folding mechanism.

Inventive Principle:
Principle #15Dynamics

4Volume of moving object

If the receptacle is designed to be collapsible into a flat shape, then the storage efficiency is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvestorage volumeVSAvoiddesign complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The receptacle is segmented into foldable sections that can be collapsed back into the original flat blank configuration for storage. The same fold lines used for assembly enable disassembly and collapsing, allowing the receptacle to return to a compact 2D state that occupies minimal storage space.

Inventive Principle:
Principle #1Segmentation
