Solution Overview

Problem

Conventional cargo trailer walls and floors are heavy due to foam filling and require complex, labor-intensive installation methods, leading to issues like snagging, water leakage, and increased manufacturing costs, while traditional riveting methods concentrate forces and create premature fractures.

Innovation Solution

A lightweight, strong trailer wall apparatus featuring vertically elongated logistics posts attached to sandwich panels with alternating peaks and valleys, using adhesive bonding and internal lips for alignment, eliminating the need for rivets and allowing gravity to secure the posts during curing, thus reducing weight, snagging, and manufacturing complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional riveting methods are used to attach logistics posts to wall panels, then strong attachment is achieved, but force concentration causes premature wall panel fractures and water leakage through rivet holes

Engineering Contradiction:

Improveattachment strengthVSAvoidwall panel durability

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The invention extracts the riveting attachment method and replaces it with adhesive bonding. The logistics post is attached to the wall panel using adhesive applied to the rear surface of the post, eliminating rivet holes and localized force concentration that cause panel fractures and water leakage.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical riveting system is replaced with a chemical adhesive bonding system. The adhesive creates a distributed bonding interface across the entire rear surface of the logistics post, replacing the localized mechanical fastening that concentrates forces and damages the panel.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Strength

If foam filling is used in conventional trailer walls, then structural strength is improved, but weight increases and recycling becomes difficult

Engineering Contradiction:

Improvewall strengthVSAvoidtrailer weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The invention discards the foam filling material that prevents recycling and replaces it with a recyclable sandwich panel construction. The sandwich panel uses lightweight core material (such as honeycomb or corrugated structure) that provides structural strength while being recyclable, eliminating the weight penalty and environmental burden of foam.

Inventive Principle:

Principle #34Discarding and recovering

3Adaptability or versatility

If conventional tracks and posts are used, then cargo securing functionality is provided, but they protrude into cargo space and are prone to snagging

Engineering Contradiction:

Improvecargo securing capabilityVSAvoidcargo snagging

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The logistics post is nested within a depression or recess in the wall panel. This nesting arrangement allows the post to be integrated into the wall structure rather than protruding into the cargo space, eliminating the snagging hazard while maintaining cargo securing functionality through the post's attachment to horizontal tracks.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Ease of manufacture

If traditional assembly methods with multiple loose parts are used, then attachment is achieved, but assembly complexity and labor intensity increase

Engineering Contradiction:

Improveassembly easeVSAvoidassembly complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The invention merges the logistics post with the wall panel assembly process. The post is attached to the wall panel using adhesive bonding during the panel assembly process itself, rather than requiring separate attachment operations with multiple loose parts like rivets and brackets. This integration simplifies the overall assembly process and reduces labor intensity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A trailer wall apparatus includes at least one logistics post. In another aspect, a vertically elongated cargo-securing or logistics post is attached adjacent to a vertically elongated depression within a sandwich panel of a cargo container, the sandwich panel employing at least one core sheet including alternating peaks and valleys therein in addition to attached interior and exterior face sheets. A further aspect employs a logistics post including internal lips which contact against and/or assist with alignment to diagonal surfaces of a depression in a container or trailer wall.
