Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual sand grain loading is used, then the device structure is simple, but the testing efficiency is low and dust is generated

Engineering Contradiction:

Improvetesting efficiencyVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The sand pump automatically conveys sand grains from the storage hopper to the impact box without manual intervention. The system serves itself by using the sand pump to handle the sand grain loading process, eliminating the need for manual operation and thereby improving testing efficiency while preventing dust generation through enclosed automatic handling.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A sand pump is introduced to automatically convey sand grains from the storage hopper to the impact box. This hydraulic/pneumatic mechanism replaces manual loading, significantly improving testing efficiency and eliminating dust generation through enclosed automatic sand grain handling.

Inventive Principle:

Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If unadjustable impact height is used, then the device structure is simple, but the adaptability is poor

Engineering Contradiction:

Improveimpact height adjustabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The impact height is made adjustable by introducing a height adjustment mechanism that allows the impact box to be positioned at different vertical levels. This dynamic adjustment capability enables the device to adapt to different testing requirements while maintaining operational simplicity through a straightforward mechanical adjustment system.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If manual recording of sand grain weights is used, then the device structure is simple, but the measurement precision is poor due to recording errors

Engineering Contradiction:

Improvesand output measurement accuracyVSAvoiddevice structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The sand pump's operation time is recorded and used as feedback to calculate the sand output quantity. This feedback mechanism eliminates manual recording errors by automatically tracking the sand delivery process through time measurement, thereby improving measurement precision while keeping the device structure relatively simple.

Inventive Principle:

Principle #23Feedback

4Object-affected harmful factors

If open hopper structure is used, then the device structure is simple, but dust is generated causing harm to human bodies and environmental pollution

Engineering Contradiction:

Improvedust generationVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A sealing cover plate is introduced to enclose the hopper opening, creating a closed system that prevents sand grain dust from escaping into the environment. This flexible sealing approach effectively eliminates dust generation and its harmful effects while maintaining relatively simple device structure through the addition of a cover plate.

Inventive Principle:

Principle #30Flexible shells and thin films
