Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a glass plate with sufficient weight is used as the smoother plate, then the surface of the molded body can be smoothed, but the load applied cannot be adjusted for different product types or sizes

Engineering Contradiction:
Improvesurface smoothnessVSAvoidload adjustment capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The smoother plate is made dynamically adjustable through a mechanism that allows weights to be added or removed. This enables the load applied to the molded body to be varied according to different product types or sizes, while maintaining the glass material for surface smoothness. The dynamic adjustment resolves the contradiction between fixed weight and adaptable load requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The load parameter of the smoother plate is made changeable by allowing weights to be added or removed from the glass plate. This enables optimization of the smoothing process for different molded body types and sizes while preserving the beneficial properties of glass for achieving smooth surfaces.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple smoother plates with different weights are provided, then appropriate load can be selected for different product types, but the device complexity and operation time increase due to plate changes

Engineering Contradiction:
Improveload adjustment capabilityVSAvoidnumber of smoother plates
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple weight options are merged into a single smoother plate structure. Instead of having separate plates for different loads, the invention combines a base glass plate with removable weights, allowing all load configurations to be integrated in one device. This reduces the number of separate components and simplifies the overall system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The smoother plate system is made dynamically configurable through a mechanism that allows weights to be added or removed. This eliminates the need for multiple static plates and enables continuous adaptation to different product requirements while maintaining a unified device structure.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple smoother plates with different weights are provided, then appropriate load can be selected for different product types, but manufacturing efficiency decreases due to cumbersome plate changing work

Engineering Contradiction:
Improveload adjustment capabilityVSAvoidmanufacturing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The smoother plate system allows dynamic adjustment of weights during operation, enabling quick adaptation to different product types without stopping the manufacturing process for plate changes. This significantly improves manufacturing efficiency while maintaining the ability to handle various product specifications.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The smoother plate system is designed to be easily reconfigurable by the operator through simple weight addition or removal. The self-contained weight adjustment mechanism eliminates the need for complex plate changing procedures, allowing rapid adaptation to different production requirements.

Inventive Principle:
Principle #25Self-service
