Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If alignment devices use translation members and multiple sensors to modify and detect the relative position of laminating sheets, then alignment capability is improved, but device complexity increases significantly

Engineering Contradiction:

Improvealignment precisionVSAvoiddevice complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex sensor systems and multiple translation members from traditional alignment devices. Instead, it uses a single movable abutting element that mechanically defines the alignment position through direct physical contact with the laminating sheet, removing the need for numerous sensors and complex detection systems while maintaining alignment precision.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The movable abutting element acts as an intermediary between the laminating sheet and the alignment system. It mechanically transfers the alignment position from the fixed abutting element to the laminating sheet through controlled movement, simplifying the alignment mechanism while maintaining precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If cutting blades are used to cut the cardboard web to size based on laminating sheet position, then alignment is achieved, but significant cardboard waste is generated

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent performs preliminary alignment action by positioning the laminating sheet correctly using the movable abutting element before the lamination process occurs. This preliminary positioning ensures proper alignment without requiring subsequent cutting or trimming operations, thereby preventing cardboard waste.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 1:

The patent replaces complex sensor-based detection and control systems with a simple mechanical system consisting of movable and fixed abutting elements. This mechanical substitution eliminates the need for numerous sensors and complex control operations, enabling high-speed laminating while maintaining alignment precision through direct mechanical positioning.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 1:

The patent extracts and eliminates multiple independent movement members from the alignment system. Instead, it uses a single movable abutting element that moves in coordination with the laminating sheet's feeding motion, dramatically simplifying the device while maintaining alignment capability through the interaction between the movable and fixed abutting elements.

AI summary

An alignment device for aligning laminating sheets in a corrugated cardboard laminator may include, one after another along a transport path of the laminating sheets in a forward feeding direction: a first transport unit configured to transport the laminating sheets at transport speed; a first acceleration unit configured to increase the transport speed of the laminating sheets; and a second transport unit. The second transport unit may include at least one first movable abutting element transverse to the forward feeding direction of the laminating sheets and configured to align the laminating sheets.
