Solution Overview

Problem

Existing workpiece positioning and clamping systems have limited vertical adjustment flexibility, leading to increased costs and complexity due to the need for specially manufactured parts to accommodate varying production conditions, particularly in industries handling complex metal, plastic, or glass-plastic components.

Innovation Solution

A modular vertical adjustment apparatus comprising two compatible modules, a stationary base and a movable vertical adjustment component, with a screw shaft and nuts for precise height adjustment, and additional components like tensioners and through-bores to prevent shear dislocation, allowing for a broad range of vertical adjustment from 225 to 1025 mm with standardized components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional clamping systems with limited vertical adjustment are used, then device complexity is reduced, but adaptability deteriorates due to inability to accommodate varying production conditions

Engineering Contradiction:
Improvevertical adjustment flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamping system is divided into modular components including a base unit, vertical adjustment mechanism with standardized increments, and interchangeable clamping elements. This segmentation allows independent optimization of each module while maintaining overall system flexibility, enabling adaptation to different workpiece heights without redesigning the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vertical adjustment mechanism is designed with standardized components that can accommodate multiple workpiece sizes and clamping requirements through a single unified system. The adjustable height range and modular design enable one system to perform multiple functions across different production conditions, eliminating the need for specially manufactured parts for each application.

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

2Ease of manufacture

If standardized modular components are used, then ease of manufacture is improved, but manufacturing precision may deteriorate without precise positioning mechanisms

Engineering Contradiction:
Improvestandardized component productionVSAvoidpositioning accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

Positioning features such as dowel pins, locating surfaces, and pre-drilled holes are incorporated into the modular components during manufacturing. These preliminary positioning actions ensure that when standardized components are assembled, they automatically achieve precise alignment and positioning without requiring complex adjustment procedures or specialized machining at the assembly stage.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If multiple specialized components are manufactured for different heights, then positioning precision is improved, but loss of substance increases due to more parts

Engineering Contradiction:
Improveworkpiece positioning accuracyVSAvoidnumber of parts
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The system replaces multiple static, height-specific components with a single dynamic vertical adjustment mechanism that can be reconfigured for different heights. This dynamic capability allows the same physical components to serve multiple positioning requirements, eliminating the need to manufacture and store numerous specialized parts for different workpiece dimensions.

Inventive Principle:
Principle #15Dynamics

4Manufacturing precision

If complex adjustment mechanisms are used, then positioning precision is improved, but ease of operation deteriorates due to trained personnel requirements

Engineering Contradiction:
Improveheight adjustment precisionVSAvoidoperational simplicity
Core Design Contradiction:

Solution Approach 1:

The vertical adjustment mechanism incorporates self-aligning features, tactile feedback, and standardized interfaces that enable operators to achieve precise positioning through intuitive operation without extensive training. The design includes features such as self-centering locators, clear visual indicators, and tool-free adjustment capabilities that allow even inexperienced operators to achieve accurate positioning consistently.

Inventive Principle:
Principle #25Self-service
