Solution Overview

Problem

Current pallets with friction elements fail to securely stabilize bottle crates, especially when stacked or positioned on top of another pallet, and lack effective wear resistance on the bottom surface during transportation and storage.

Innovation Solution

The pallet design incorporates friction elements with an upper and lower collar and a middle portion, integrated into the deck openings, which provide enhanced friction and stability by gripping the rim of bottle crates and featuring grooves for water drainage, along with additional friction provisions on the top and bottom decks to prevent sliding and wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If friction elements are added to secure bottle crates, then stability and anti-slip performance are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvestability of bottle cratesVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The friction elements are integrated into the pallet deck structure by inserting them into openings in the deck surface. The friction elements become part of the pallet structure, combining the pallet body with the friction-enhancing components into a unified system that secures bottle crates without requiring separate external devices

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The deck is designed with openings that accommodate the friction elements. These openings create a porous-like structure in the deck surface, allowing the friction elements to protrude and provide grip while maintaining structural integrity of the pallet

Inventive Principle:
Principle #31Porous materials

2Reliability

If friction elements protrude above deck surface, then friction and grip are improved, but wear resistance and structural integrity worsen

Engineering Contradiction:
Improvefriction between pallet and cratesVSAvoidwear resistance of deck
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The friction elements are positioned at specific locations on the pallet deck where grip is needed, rather than covering the entire surface. The elements have varying heights and are strategically placed to provide localised friction enhancement while preserving the overall structural integrity and wear resistance of the deck

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The deck is segmented into multiple openings that accommodate individual friction elements. This segmentation allows the friction elements to be distributed across the pallet surface, providing grip where needed while maintaining the structural strength of the deck between the openings

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If friction elements are added to stabilize stacked pallets, then stack stability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvestability of pallet stackVSAvoidpallet manufacturing
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The friction elements are integrated into the pallet manufacturing process itself, with openings for the elements being formed as part of the deck structure. This merging of the friction element installation with the pallet manufacturing reduces overall complexity compared to adding separate stabilization components after pallet production

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The friction elements on the bottom deck automatically engage with the rims of bottle crates on pallets below when stacked, providing self-stabilization of the pallet stack without requiring additional active components or complex assembly steps

Inventive Principle:
Principle #25Self-service
