Solution Overview

Problem

Marking devices with adjustable print bands, such as daters and numberers, face challenges in user efficiency due to small, difficult-to-manage adjustment wheels, lack of visibility into current settings, and the risk of ink stains from self-inking mechanisms.

Innovation Solution

A self-inking marking device with a single adjustment knob and a display interface for clear viewing of print band settings, eliminating the need for manual rotation of multiple wheels and reducing the risk of ink stains by keeping the ink-receiving surface out of direct user contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple small adjustment wheels are used for each print band, then each band can be adjusted independently, but the device complexity increases and ease of operation deteriorates due to difficulty in managing multiple tiny wheels

Engineering Contradiction:

Improveindependent band adjustmentVSAvoiddifficulty in adjusting multiple tiny wheels

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple adjustment wheels for different print bands are merged into a single shared adjustment wheel. The wheel is positioned to simultaneously engage with multiple bands, allowing one rotational motion to adjust all bands in unison, thereby simplifying the adjustment process while maintaining independent band control

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A single adjustment wheel serves multiple functions by controlling all print bands simultaneously. This universal adjustment mechanism eliminates the need for separate wheels for each band, reducing device complexity and improving ease of operation while preserving the ability to independently adjust each band's position

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If adjustment wheels are placed within a recessed housing, then the device structure is compact, but ease of operation worsens due to increased difficulty in accessing and turning the wheels

Engineering Contradiction:

Improvedevice compactnessVSAvoiddifficulty in accessing adjustment wheels

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The adjustment wheel is extracted from the recessed housing and positioned on the external surface of the device body. This extraction allows the wheel to be easily accessible to users while the housing structure remains compact, resolving the contradiction between device compactness and ease of adjustment access

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If the die plate is pivoted from a retracted inking position to a forward printing position, then the self-inking mechanism functions properly, but visibility of the print interface deteriorates as the user must invert the device to view the settings

Engineering Contradiction:

Improveself-inking mechanism functionVSAvoidvisibility of print interface settings

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of requiring the user to invert the device to view the print interface, the display of adjusted values is inverted or mirrored on the visible surface. This allows the user to view the correct orientation of text and values while the die plate remains in its functional printing position, maintaining both mechanism reliability and interface visibility

Inventive Principle:

Principle #13The other way round (Inversion)

4Force

If the user must press the handle with one hand and stabilize the body with the other to adjust bands, then the spring force can be managed, but productivity decreases due to the complex two-handed coordination required

Engineering Contradiction:

Improvespring force managementVSAvoidadjustment efficiency

Core Design Contradiction:

ForceVSProductivity

Solution Approach 1:

The device is designed so that the die plate automatically returns to its neutral retracted position after each stamping action, eliminating the need for manual stabilization during adjustment. This preliminary positioning allows users to adjust bands with a single hand without worrying about spring force or device stability, thereby improving adjustment efficiency

Inventive Principle:

Principle #10Preliminary action

AI summary

A self-inking marking device having adjustable print bands configured to be adjustable by a single adjustment knob, with a readily viewable display for viewing the current status of the print interface. In an embodiment, a self-inking marking device generally includes a display interface, an upper body, a lower body, adjustment components, and printing components. The printing components include components to affect a unique self-inking method that utilizes an ink roller that inks the die while rolling along the surface of the die plate.
