Solution Overview

Problem

Existing double-sided scanning technologies often result in paper twisting and jams due to the need for paper sheets to turn over between scanners, which is not efficiently managed by traditional block-based mechanisms.

Innovation Solution

A paper feeding module with a ramp and actuation mechanism that includes a motor-driven cam and solenoid valve, allowing for controlled movement of a carrier and press block to maintain paper flatness and prevent distortion, enabling smooth double-sided scanning without jams.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If another scanner is added adjacent to the first scanner for double-sided scanning, then both sides of the paper sheet can be scanned, but the paper sheet must turn over instantly which causes twisting and paper jams

Engineering Contradiction:
Improvedouble-sided scanning capabilityVSAvoidpaper sheet stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent positions the second scanner in a different spatial dimension (opposite side of the slot channel) and uses a ramp structure to guide paper sheets through a controlled three-dimensional path. This dimensional arrangement allows both scanners to operate simultaneously without requiring instant paper turnover, eliminating twisting and jams while maintaining double-sided scanning capability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a block is used to press paper sheets for instant turnover between scanners, then the paper sheet can reach the second scanner, but this causes twisting of the paper sheets and paper jams

Engineering Contradiction:
Improvepaper sheet conveyanceVSAvoidpaper sheet flatness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the rigid block pressing mechanism with a ramp structure that provides a curved, inclined surface for paper sheet guidance. This curved path allows paper sheets to transition smoothly between scanners without abrupt pressing or twisting, maintaining paper flatness while ensuring reliable conveyance to the second scanner.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
