Solution Overview

Problem

Existing financial devices face challenges in accurately determining the genuineness of media, such as paper money and coins, due to issues with sensor detection and support mechanisms, leading to potential errors and decreased accuracy.

Innovation Solution

A medium process apparatus is designed with a state detection unit and a support unit comprising multiple support parts, where the support unit is rotatably disposed and applies an elastic force to compress the medium towards the detection unit, ensuring accurate detection by minimizing paper dust interference and maintaining smooth medium transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the support unit is fixed and stationary, then the structure is simple, but the medium cannot be compressed toward the detection unit effectively

Engineering Contradiction:

Improvecompression forceVSAvoidsupport unit structure

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The support unit is made rotatable about a rotation axis instead of being fixed, allowing it to dynamically adjust its position and apply compression force to the medium. The elastic member enables the support unit to rotate and press the medium against the detection unit, transforming a static structure into a dynamic compression mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent replaces a complex multi-component compression mechanism with a simpler rotatable support unit combined with an elastic member. The elastic member stores and releases mechanical energy to provide the necessary compression force, eliminating the need for additional actuators or complex mechanical linkages.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If the support unit is spaced from the detection unit, then the medium can pass through, but paper dust may interfere with detection accuracy

Engineering Contradiction:

Improvedetection accuracyVSAvoidpaper dust interference

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The support unit rotates to a position where it contacts the detection unit before the medium passes through, performing a preliminary cleaning action. This preliminary contact removes paper dust from the detection unit surface, preventing dust interference during subsequent medium detection.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The support unit acts as an intermediary element that mediates between the medium and the detection unit. By rotating to contact the detection unit, it serves as a cleaning intermediary that removes contaminants before the medium is detected, ensuring accurate measurement.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If multiple support parts are used, then the medium is supported more stably, but the device complexity increases

Engineering Contradiction:

Improvemedium support stabilityVSAvoidsupport unit structure

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The support unit is segmented into multiple support parts (first support part and second support part) that are spaced apart in the transfer direction. This segmentation allows the support unit to contact and support the medium at multiple points, enhancing stability without requiring a completely complex structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support parts are arranged in the transfer direction (longitudinal dimension) rather than solely in the vertical dimension. This dimensional arrangement provides stable medium support while keeping the overall structure relatively simple, as the support parts can be integrated into the rotatable support unit.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
