Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing levelling devices are used, then levelling function is achieved, but device complexity and difficulty of operation increase

Engineering Contradiction:
Improveease of useVSAvoidconstruction complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device is divided into modular components: a telescopic bar with adjustable length, separate feet with connection mechanisms, and independent adjustment systems. This segmentation allows each component to perform its specific function simply, reducing overall device complexity while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The telescopic bar features dynamic adjustability through sliding sections and rotation mechanisms, allowing the device to adapt to various wall heights and angles. This dynamic capability enables easy operation across different scenarios without requiring multiple fixed-configuration devices.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If telescopic bar with adjustment mechanism is used, then adaptability to irregular surfaces improves, but device complexity increases

Engineering Contradiction:
Improveadaptability to irregularitiesVSAvoidadjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device utilizes parameter changes through the threaded shaft mechanism, where rotational movement is converted to linear displacement. This allows continuous adjustment of the telescopic bar angle and position, providing adaptability to irregular surfaces through simple parameter variation rather than complex mechanical systems.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The connection and guide mechanism replaces complex mechanical linkages with a simpler system combining rollers for movement and a threaded shaft for angular adjustment. This substitution reduces device complexity while maintaining versatility in accommodating floor and ceiling irregularities.

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

3Measurement precision

If multiple devices form a system, then levelling precision improves, but setup time increases

Engineering Contradiction:
Improvelevelling precisionVSAvoidsetup time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

Each device in the system is designed as a universal module that can function independently or in combination with others. The standardized connection mechanisms and identical structural design allow multiple devices to be quickly assembled into a coordinated system, achieving high levelling precision without proportionally increasing setup time.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The device enables fast and easy setup for constructing levelled surfaces, accommodating irregularities and simplifying the levelling process without requiring extensive knowledge, ensuring a satisfactory levelled wall.

Implementation Method 1

The foot bar comprises a threaded hole which is made for a threaded shaft that rotatably connected to the telescopic bar and also engaged with same threaded hole of the foot bar so that rotational movement of the threaded shaft through the engagement of the threaded hole of the foot bar is transferred into linear motion of the telescopic bar along the foot

Methodology Applied
Scientific EffectScrew mechanism: Screw

Implementation Method 2

The connection and guide mechanism comprises at least two rollers rotatably connected to the end portion of the telescopic bar so that rollers can roll along the foot. The rollers also supporting the telescopic bar against the feet.

Methodology Applied
Scientific EffectRolling: Roller

Implementation Method 3

The adjusting and locking device is a rack and pinion mechanism. The rack is rotatably installed in one tube of the telescopic bar and the pinion is fixed to another tube of the telescoping bar so that a rotation of the rack provides interrelated linear movement between the tubes of the telescopic bar.

Methodology Applied
Scientific EffectRack and pinion: Rack and Pinion
