Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a combined structure of vibration device and screening device is used to achieve screening of different sizes of bolts, then screening capability is improved, but device complexity increases and efficiency does not improve

Engineering Contradiction:

Improvescreening capabilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the vibration device and screening device into a single integrated unit where the vibrating disk itself serves as the screening surface. The feeding rail is arranged inside the vibrating disk, and the removing slant knife is integrated into the disk structure, eliminating the need for separate screening devices and reducing overall structural complexity while maintaining multi-size screening capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The vibrating disk performs multiple functions simultaneously: it vibrates to move bolts, serves as the screening surface with integrated feeding and removing mechanisms, and the rotating removing slant knife provides selective screening. This multi-functional design reduces the number of separate components needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If bolts are conveyed from bottom to top to overcome gravity, then screening function is achieved, but energy consumption increases

Engineering Contradiction:

Improvescreening functionVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of conveying bolts from bottom to top against gravity, the patent inverts the approach by allowing bolts to slide from top to bottom under gravity's influence. The vibrating disk creates vibration that facilitates this downward motion while maintaining effective screening, thereby reducing energy consumption.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent utilizes the gravitational potential energy naturally available by positioning the feeding end at the top and the discharge end at the bottom. Bolts move downward under gravity without requiring additional energy input to overcome gravitational force, making the system more energy-efficient.

Inventive Principle:

Principle #12Equipotentiality

3Device complexity

If manual visual inspection and manual screening are used, then screening process is simple, but screening precision and efficiency are low

Engineering Contradiction:

Improveprocess simplicityVSAvoidscreening accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces manual visual inspection and manual screening operations with an automated mechanical system. The vibrating disk with integrated feeding rail and removing slant knife automatically screens bolts by size, eliminating human involvement in the screening process while improving both accuracy and efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Device complexity

If a single screening rail and screening port are used, then device structure is simple, but multiple types of bolts cannot be screened simultaneously

Engineering Contradiction:

Improvestructure simplicityVSAvoidmulti-type screening capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a rotating removing slant knife that can be adjusted to different positions and angles. This dynamic element allows the single screening structure to adapt to different bolt types and sizes by changing the knife's position, enabling multi-type bolt screening without requiring multiple fixed screening rails.

Inventive Principle:

Principle #15Dynamics
