Solution Overview

Problem

Current rear protection equipment in trailer and semi-trailer vehicles requires additional components to prevent chassis deformations during loading and unloading, leading to increased costs, weight, and technical issues, such as complex attachment methods.

Innovation Solution

A foldable and extendable rear protection bumper that acts as a mechanical foot, integrating all necessary components to absorb sudden pressures from forklifts by adjusting its height and angle, eliminating the need for separate components and simplifying attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional components are attached to the rear protection equipment to prevent chassis deformations, then the protection effectiveness is improved, but the device complexity, weight, and cost increase

Engineering Contradiction:
Improveprotection effectivenessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the rear protection equipment and the additional protection component into a single integrated bumper assembly. The bumper includes a main body and an extended portion that works together as one unit to prevent chassis deformations, eliminating the need for separate attached components while maintaining enhanced protection effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated bumper serves multiple functions: it provides rear collision protection, prevents chassis deformations during loading/unloading, and acts as a structural reinforcement element. This multi-functional design replaces what would otherwise require multiple separate components, reducing overall device complexity while maintaining comprehensive protection.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If additional components are attached to the rear protection equipment, then the protection effectiveness is improved, but the weight increases

Engineering Contradiction:
Improveprotection effectivenessVSAvoidweight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

By merging the protection functions into a single integrated bumper structure, the patent eliminates the weight of separate attachment components, fasteners, and mounting hardware that would be required if additional components were attached separately. The integrated design achieves the same protection effectiveness with reduced total weight.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If additional components are attached to the rear protection equipment, then the protection effectiveness is improved, but the cost increases

Engineering Contradiction:
Improveprotection effectivenessVSAvoidcost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The integrated bumper design reduces manufacturing costs by eliminating the need to manufacture, inventory, and assemble multiple separate components. The single-piece or pre-assembled integrated structure requires fewer manufacturing steps, less inventory management, and simpler assembly procedures compared to attaching additional components to existing rear protection equipment.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If additional components are attached to the rear protection equipment, then the protection effectiveness is improved, but the attachment complexity increases

Engineering Contradiction:
Improveprotection effectivenessVSAvoidattachment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the additional protection element directly into the bumper structure, eliminating the need for separate attachment procedures. The extended portion and main body are designed to work together as a unified structure, removing the complexity of attaching, aligning, and securing additional components to the existing rear protection equipment.

Inventive Principle:
Principle #5Merging (Combining)
