Solution Overview

Problem

Construction operations such as relief cuts and repetitive tasks in construction sites are labor-intensive, time-consuming, and prone to human error, especially when performed manually, and require quick and accurate execution before materials set, like concrete.

Innovation Solution

A construction site status monitoring device that receives teaching data from construction devices in a teaching mode to generate an operation profile, enabling other devices to repeat the operation accurately and efficiently, with parameters like depth, length, direction, force, current, and voltage, and communicates these profiles wirelessly or through data storage for execution by multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual operations are performed by operators, then flexibility and adaptability are maintained, but labor intensity and time consumption increase significantly

Engineering Contradiction:
Improveoperation speedVSAvoidlabor intensity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The construction device performs operations autonomously based on stored operation profiles without requiring continuous manual intervention. The device self-regulates parameters such as depth, speed, and force according to pre-programmed sequences, enabling automatic execution of repetitive tasks like relief cuts and stitch drilling.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Operation profiles are pre-programmed and stored in memory before actual construction operations begin. These profiles contain all necessary parameters and sequences for operations such as relief cuts and patterned drilling, allowing the device to execute them automatically without real-time manual control.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual operations are performed, then human judgment and adaptability are utilized, but human error and inconsistency increase in repeated operations

Engineering Contradiction:
Improveoperation accuracyVSAvoidconsistency
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

Sensors monitor operational parameters such as depth, force, and position in real-time and provide feedback to the control system. This feedback mechanism ensures that operations remain within specified tolerances and automatically adjusts parameters to maintain precision and consistency across repeated operations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Successful operation sequences are captured and stored as standardized profiles that can be replicated across multiple operations and different devices. This copying mechanism ensures identical reproduction of precise operations such as relief cuts and stitch drilling patterns without variation.

Inventive Principle:
Principle #26Copying

3Loss of time

If construction operations are delayed, then operator fatigue and errors may occur, but rushing operations may compromise quality and accuracy

Engineering Contradiction:
Improveoperation timeVSAvoidoperation quality
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The control system dynamically adjusts operational parameters such as speed, feed rate, and force application based on real-time conditions and profile requirements. This dynamic control enables rapid execution of operations like relief cuts while maintaining precise depth control and cut quality through automated parameter optimization.

Inventive Principle:
Principle #15Dynamics
