Dump Truck Front Bumper Mounting for Interchangeable Equipment

Solution Overview

Problem

Existing dump trucks face challenges in standardizing the vehicle body frame due to the need for different types of equipment, such as standard and special radiators, and pantographs, which complicates the joint strength and manufacturing, making it difficult to easily change specifications.

Innovation Solution

A dump truck design with a vehicle body frame that includes a front bumper equipped with a base fixing section allowing multiple types of device mounting bases to be selectively fixed, enabling the attachment of various equipment types while ensuring joint strength through integral fixation to the main frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a front bumper corresponding to each type of device is replaceably attached to the main frame, then different types of equipment can be mounted, but the joint strength between the front bumper and main frame becomes insufficient due to lifting loads

Engineering Contradiction:

Improveequipment type interchangeabilityVSAvoidjoint strength between front bumper and main frame

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The front bumper system is segmented into a main front bumper structure and detachable device mounting bases. The main bumper remains permanently attached to the main frame to ensure structural strength, while device mounting bases are selectively attached to the front bumper to accommodate different equipment types. This segmentation allows the strong main bumper to handle lifting loads while interchangeable bases provide equipment adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Device mounting bases serve as intermediary components between the front bumper and various equipment (radiators, pantographs). These bases are selectively attached to the front bumper's base fixing section, allowing different equipment types to be mounted without directly attaching to the main frame. The intermediary bases enable equipment interchangeability while the main bumper maintains structural integrity for lifting operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If a front bumper is fixed non-replaceably to the main frame, then joint strength is ensured, but the vehicle body frame cannot be standardized and manufacturing becomes complex

Engineering Contradiction:

Improvejoint strength between front bumper and main frameVSAvoidvehicle body frame standardization

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The front bumper system is segmented into a main front bumper structure and detachable device mounting bases. The main bumper remains permanently attached to the main frame to ensure structural strength, while device mounting bases are selectively attached to the front bumper to accommodate different equipment types. This segmentation allows the strong main bumper to handle lifting loads while interchangeable bases provide equipment adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single standardized front bumper design with a universal base fixing section can accommodate multiple types of equipment through interchangeable device mounting bases. This universal front bumper design enables standardization of the vehicle body frame across different dump truck models, while still allowing customization for different equipment requirements through the selective attachment of appropriate mounting bases.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If different types of equipment are mounted on the front bumper, then equipment versatility is achieved, but the base fixing section must accommodate multiple mounting configurations

Engineering Contradiction:

Improveequipment type varietyVSAvoidbase fixing section configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single standardized front bumper design with a universal base fixing section can accommodate multiple types of equipment through interchangeable device mounting bases. This universal front bumper design enables standardization of the vehicle body frame across different dump truck models, while still allowing customization for different equipment requirements through the selective attachment of appropriate mounting bases.

Inventive Principle:
