Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional level devices are used, then they can determine horizontal or vertical surfaces, but they are cumbersome and difficult to use in environments with unique workpiece configurations

Engineering Contradiction:
Improveease of useVSAvoidadaptability to unique workpiece configurations
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The level device is divided into a main body and a separate extension component. The extension can be attached to the main body to reach into confined spaces or unique configurations, then detached when not needed. This segmentation allows the device to adapt to various workpiece configurations while maintaining ease of use through modular assembly and disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The level device incorporates a movable extension component that can be dynamically attached or detached from the main body. This dynamic configuration allows the device to transition between different operational states (standard mode and extended reach mode), providing versatility for unique workpiece configurations while maintaining simple operation through straightforward attachment mechanisms.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If conventional level devices are used, then they have a fixed structure, but they cannot accommodate various workpiece configurations or provide extended reach

Engineering Contradiction:
Improveaccommodation of various workpiece configurationsVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The level device is divided into a main body and a separate extension component. The extension can be attached to the main body to reach into confined spaces or unique configurations, then detached when not needed. This segmentation allows the device to adapt to various workpiece configurations while maintaining ease of use through modular assembly and disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The extension component is designed with universal attachment capability to the main body, allowing the same extension to be used with different main bodies or different extensions to be used with the same main body. This universality provides adaptability to various workpiece configurations without requiring complex custom-designed components for each scenario.

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

3Productivity

If a level device with multiple reference surfaces and bubble vials is used, then multiple surfaces can be assessed simultaneously, but the device becomes more complex

Engineering Contradiction:
Improveefficiency of surface assessmentVSAvoidstructural complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Multiple reference surfaces and bubble vials are merged into a single integrated main body structure. The first and second reference surfaces are positioned at right angles to each other, allowing simultaneous assessment of multiple surfaces without requiring multiple separate level devices. This merging provides productivity benefits while maintaining relatively simple device structure through integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The level device incorporates reference surfaces and bubble vials in different spatial dimensions and orientations. The first reference surface and second reference surface are positioned at right angles, allowing the device to assess surfaces in multiple dimensions simultaneously. This dimensional arrangement enables efficient multi-surface assessment without significantly increasing overall device complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Length of moving object

If a leveling extension is added to the level device, then extended reach is enabled, but the device requires additional attachment mechanisms

Engineering Contradiction:
Improvereach distanceVSAvoidattachment mechanism complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The level device is divided into a main body and a separate extension component. The extension can be attached to the main body to reach into confined spaces or unique configurations, then detached when not needed. This segmentation allows the device to adapt to various workpiece configurations while maintaining ease of use through modular assembly and disassembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An attachment mechanism serves as an intermediary between the main body and the extension component. This intermediary provides a simple, standardized interface for connecting and disconnecting the extension, enabling extended reach functionality without requiring complex integration mechanisms. The attachment mechanism simplifies the connection process while providing secure coupling.

Inventive Principle:
Principle #24Intermediary (Mediator)
