Solution Overview

Problem

Existing shelf frame assembly systems require complex assembly processes with glue dams and screws, which can be cumbersome and not fully effective in preventing glue seepage and ensuring a secure, corrosion-resistant, and cost-effective solution.

Innovation Solution

The proposed system employs quick connect construction features such as press-fitting components, tool-less assembly, and barbed components to securely attach side beams to vertical posts, using protrusions and recesses to resist horizontal withdrawal and ensure a secure fit without the need for glue or screws.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional assembly methods using glue dams and screws are employed, then joint strength and glue containment are improved, but assembly complexity and time consumption increase

Engineering Contradiction:
Improvejoint strengthVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the glue dam component entirely from the assembly system. Instead of using separate glue dams to contain hot melt glue, the design integrates glue containment directly into the beam structure through recesses and channels, eliminating the need for additional components and simplifying the assembly process while maintaining joint strength

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines multiple functions into the beam structure itself: the beams include integrated recesses for glue containment, channels for glue flow control, and positioning features for alignment. This merging of functions eliminates the need for separate glue dams and reduces assembly complexity while maintaining reliable joints

Inventive Principle:
Principle #5Merging (Combining)

2Object-generated harmful factors

If glue dams are used to prevent glue seepage, then clean interface and reduced cleanup are improved, but assembly complexity increases

Engineering Contradiction:
Improveglue seepageVSAvoidassembly complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent integrates glue containment features directly into the beam structure through recesses and channels. The recesses create clean interfaces by containing the glue within defined boundaries, while the channels control glue flow to prevent seepage. This eliminates the need for separate glue dam components while achieving the same harmful factor prevention

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses integrated recesses and channels as intermediary structures within the beams to control glue behavior. These features act as built-in mediators that contain and direct the hot melt glue, preventing it from seeping out while maintaining a clean interface between components

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple components (glue dams, screws, fixtures) are used for assembly, then joint security is improved, but manufacturing cost and assembly time increase

Engineering Contradiction:
Improvejoint securityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent removes multiple components from the assembly system: glue dams are eliminated through integrated recesses, and screws are replaced with snap-fit mechanisms. This reduction in component count directly decreases assembly time and increases productivity while maintaining joint security through the simplified but effective snap-fit and integrated glue containment system

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements self-aligning and self-securing features through the beam design. The recesses and positioning features automatically guide components into correct alignment during assembly, and the snap-fit mechanisms provide automatic locking without requiring additional fastening operations, thereby reducing assembly time while ensuring reliable joints

Inventive Principle:
Principle #25Self-service
