Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional label attachment device uses a fixed-size pad, then it can pick up labels of that specific size, but it requires separate pads for different label sizes and necessitates pad replacement when label sizes change

Engineering Contradiction:

Improvecapability to handle various label sizesVSAvoidnumber of pads and replacement operations

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pad part is designed with multiple cells whose heights can be independently adjusted. By changing the height of each cell, the overall shape of the pad part can be dynamically modified to match different label sizes and contours, enabling a single pad structure to adapt to various label dimensions without replacement

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pad part is divided into multiple independent cells, each capable of individual height adjustment. This segmentation allows different portions of the pad to be configured at different heights, creating complex shapes that can conform to labels of various sizes and geometries from a single pad structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a label attachment device uses multiple pads for different label sizes, then it can handle diverse label dimensions, but it requires separate space for loading multiple pads

Engineering Contradiction:

Improvesupport for diverse label sizesVSAvoidspace for loading pads

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

A single pad part with adjustable cell heights serves multiple functions by configuring different cell heights to match various label sizes. This universal pad structure eliminates the need for multiple dedicated pads, reducing the space required for pad storage and loading while maintaining the capability to handle diverse label dimensions

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If a label attachment device requires pad replacement as label sizes change, then it maintains precision for each label size, but it increases operation time and reduces productivity

Engineering Contradiction:

Improveattachment precision for specific label sizesVSAvoidlabel attachment throughput

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The ability to dynamically adjust cell heights allows the pad shape to be quickly reconfigured between different label sizes without physical replacement. This reduces downtime between production runs of different label sizes while maintaining the precision needed for each specific size through proper shape matching

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pad cells can be pre-configured to specific heights corresponding to different label sizes. This preliminary configuration allows for quick switching between label sizes by simply adjusting cell heights rather than replacing entire pads, thereby maintaining precision while improving operational efficiency

Inventive Principle:

Principle #10Preliminary action
