Solution Overview

Problem

Current modular trailer systems require extensive time, labor, and materials for lifting and supporting large or heavy objects, leading to increased CO2 footprint and stability issues due to high load bed supports, which complicate the transport process.

Innovation Solution

A trailer system integrating a jack cradle with a jack holder and primary cradle connector, allowing for vertical and horizontal movement without switching support locations, reducing the need for external jacks and load spreaders, and enabling compact design with improved stability by positioning the jack system below the loading bed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If loading bed supports are used to lift and support objects, then the object can be transported, but the overall height of the trailer system increases requiring more free space below the object

Engineering Contradiction:
Improvetransport capabilityVSAvoidoverall height of trailer system
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The jack holder is nested within the loading bed structure, with the jack system positioned below the loading bed upper surface. This nesting arrangement allows the support function to be integrated into the existing structure without increasing the overall height, as the jack holder and jack mechanism are contained within the loading bed's structural volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The jack holder extends in the vertical dimension below the loading bed, utilizing the space underneath rather than adding height above. This dimensional repositioning allows the support mechanism to function while maintaining a compact overall profile, effectively using the unused vertical space below the loading bed for the support function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If loading bed supports are used to lift objects, then the object can be transported, but more time, labor and materials are required

Engineering Contradiction:
Improvetransport capabilityVSAvoidtransport efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The jack system is merged with the loading bed structure through the jack holder, which is rigidly connected to the loading bed. This integration combines the support function with the loading bed, eliminating the need for separate external support materials and reducing the number of components required, thereby improving transport efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The loading bed structure serves its own support function through the integrated jack holder and jack system. The loading bed includes its own built-in support mechanism, eliminating the need for external jacks and load spreaders, and allowing the system to perform the support function without additional materials or equipment.

Inventive Principle:
Principle #25Self-service

3Reliability

If loading bed supports are used to lift objects, then the object can be transported, but the CO2 footprint of the transport project increases

Engineering Contradiction:
Improvetransport capabilityVSAvoidCO2 footprint
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The loading bed includes its own integrated jack system for support, eliminating the need for external support materials that would require manufacturing and transport. This self-sufficient design reduces the material requirements and associated CO2 emissions from producing and transporting support equipment to the site.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The integrated jack system eliminates the need for disposable external support materials. The permanent, built-in support mechanism replaces single-use support equipment, reducing waste and the environmental impact associated with manufacturing and transporting temporary support materials.

Inventive Principle:
Principle #34Discarding and recovering

4Reliability

If the object is engaged at a significant height using loading bed supports, then the object can be transported, but the stability of the trailer system decreases due to high centre of gravity

Engineering Contradiction:
Improvetransport capabilityVSAvoidtrailer system stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

Instead of positioning the support mechanism above the loading bed, the jack system is inverted and positioned below the loading bed. This inversion lowers the center of gravity of the support structure, improving the stability of the trailer system when transporting objects at elevated positions.

Inventive Principle:
Principle #13The other way round (Inversion)
