Solution Overview

Problem

The existing methods for processing unpaved areas adjacent to paved roadways, typically using stationary excavators, are time-consuming, labor-intensive, costly, and pose safety risks due to limited visibility and the need for swinging and reversing, often resulting in excessive material movement and inefficient processing.

Innovation Solution

A device that attaches to the front of a construction machine's attachment, allowing for continuous and precise processing of unpaved areas without swinging, by using a fastening mechanism that enables detachable attachment to various tools, guiding the device along the paved roadway edge, and redirecting material laterally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a stationary excavator is used to process the unpaved area, then the processing can be performed with a fixed position, but the processing time increases and productivity decreases

Engineering Contradiction:

Improveprocessing stabilityVSAvoidprocessing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The device merges the functions of a stationary excavator's processing capability with the mobility of a construction machine by attaching a processing unit to the front of the construction machine, enabling continuous forward movement while processing the unpaved area

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system transitions from a static stationary excavator to a dynamic configuration where the processing unit is mounted on a mobile construction machine, allowing the entire system to move continuously through the work area without repositioning

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a stationary excavator swings and reverses to access the unpaved area, then the excavator can reach the work zone, but safety risks increase due to limited visibility

Engineering Contradiction:

Improveaccess capabilityVSAvoidsafety hazards

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

Instead of the excavator swinging and reversing to access the unpaved area, the processing unit is mounted on the front of a construction machine that drives directly forward, inverting the traditional approach and eliminating the need for dangerous swinging and reversing maneuvers

Inventive Principle:

Principle #13The other way round (Inversion)

3Power

If a stationary excavator with large attachments is used, then the processing power is sufficient, but the processing precision decreases and excessive material is moved

Engineering Contradiction:

Improveprocessing powerVSAvoidprocessing precision

Core Design Contradiction:

PowerVSManufacturing precision

Solution Approach 1:

The processing unit is designed with locally optimized features including a processing width matching the unpaved area width and a processing depth adapted to the shoulder thickness, enabling precise processing without excessive material removal while maintaining sufficient processing power

Inventive Principle:

Principle #3Local quality

4Productivity

If traditional processing methods are used, then the unpaved area can be processed, but the subsequent resurfacing effort increases

Engineering Contradiction:

Improveprocessing capabilityVSAvoidresurfacing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The device performs preliminary action by precisely processing the unpaved area to the exact required dimensions and profile before resurfacing, creating an optimally prepared base that reduces or eliminates the need for additional resurfacing work

Inventive Principle:

Principle #10Preliminary action
