Solution Overview

Problem

Existing vibration presses face challenges in precise and efficient adjustment of positioning rods, leading to inaccuracies in tamper positioning due to manual adjustment limitations and potential deviation from the vertical axis, resulting in suboptimal concrete molding.

Innovation Solution

The vibration press incorporates a positioning rod system with a holding device that allows for precise length adjustment up to 0.1 mm, featuring a movable second portion and a motor-controlled mechanism to maintain the adjusted length, ensuring accurate and consistent positioning despite vibrations and shocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual adjustment of positioning rods is used, then the device complexity is reduced, but the manufacturing precision and adjustment precision deteriorate

Engineering Contradiction:
Improveadjustment mechanism complexityVSAvoidpositioning rod adjustment precision
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical adjustment with an automated motorized system. A motor (2820) drives a screw mechanism (2808, 2810) to automatically adjust the positioning rod length, eliminating manual intervention while achieving high precision adjustment of 0.1mm or better. This substitution resolves the contradiction by using automated mechanical systems to achieve both simplicity and precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The positioning rod system incorporates self-adjustment capabilities through the motorized screw mechanism. The system can automatically compensate for deviations and maintain optimal positioning without requiring manual intervention during operation. The holding device (2804, 2806) with releasing mechanism enables the system to self-lock at the desired position, providing self-service functionality that maintains precision while reducing operational complexity.

Inventive Principle:
Principle #25Self-service

2Length of moving object

If the positioning rod length is increased, then the adjustment range is improved, but the stability deteriorates due to axis deviation

Engineering Contradiction:
Improvepositioning rod lengthVSAvoidvertical axis stability
Core Design Contradiction:
Length of moving objectVSStability of the object's composition

Solution Approach 1:

The patent employs a dynamic adjustment mechanism where the positioning rod length can be modified during operation. The motorized screw system allows real-time adjustment of the rod length to compensate for axis deviation caused by increased length. The holding device with releasing mechanism enables dynamic locking and adjustment, maintaining vertical stability even when the rod is extended to greater lengths for increased adjustment range.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If manual adjustment of positioning rods is used, then the ease of operation is improved, but the productivity deteriorates due to time-consuming adjustment

Engineering Contradiction:
Improveadjustment operation simplicityVSAvoidadjustment time
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual adjustment operations with automated motorized control. The motor (2820) automatically adjusts the positioning rod length based on programmed parameters, eliminating the time-consuming manual adjustment process. This substitution maintains operational simplicity through automated control while dramatically reducing adjustment time, thereby resolving the contradiction between ease of operation and productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs preliminary adjustment actions automatically before the molding process begins. The motorized positioning system pre-adjusts the rod length to the optimal position, and the holding device pre-locks the position. This preliminary automated action eliminates time-consuming manual adjustments during production, improving productivity while maintaining ease of operation through automated control.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If the positioning rod allows movement during operation, then the adaptability is improved, but the reliability deteriorates due to length changes

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidpositioning consistency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a dynamic positioning system where the positioning rod can be adjusted during operation through motorized control. The holding device (2804, 2806) with releasing mechanism allows controlled movement when adjustment is needed while maintaining firm locking during stable operation. This dynamic capability provides adaptability for different molding requirements while ensuring reliability through secure locking, resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #15Dynamics
