Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing food product scales face difficulties in aligning and inserting label cassettes due to a single alignment feature, especially when located on high counters, leading to inconsistent and difficult cassette loading.

Innovation Solution

A scale design featuring a load ramp and load guide with faceted surfaces that facilitate initial alignment of the cassette, allowing for easy and consistent insertion by mating the load guide with the load ramp before engaging secondary alignment features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single alignment rod and alignment hole are used for cassette insertion, then the device complexity is reduced, but the ease of operation deteriorates due to inconsistent and difficult alignment

Engineering Contradiction:

Improvealignment feature complexityVSAvoidcassette insertion ease

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The alignment system is segmented into multiple independent alignment features (first alignment feature with alignment rod and alignment hole, second alignment feature with engagement surface and protrusion) distributed along the load path. This segmentation allows progressive alignment rather than requiring perfect single-point alignment, improving ease of operation while maintaining reasonable device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first alignment feature (alignment rod and alignment hole) provides preliminary alignment of the cassette with the printer before the cassette is fully inserted. This preliminary action guides the cassette into correct position, making the overall insertion process easier and more consistent, especially from elevated positions.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the scale is located on a high counter, then the productivity is improved by better ergonomics for operators, but the ease of operation deteriorates due to difficulty in aligning and inserting cassettes

Engineering Contradiction:

Improveoperating efficiencyVSAvoidcassette loading difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The load ramp serves as an intermediary element that bridges the gap between the operator's hand position (at elevated counter height) and the cassette insertion point. The load ramp with its faceted surfaces provides a guided path that reduces the precision required for manual alignment, making insertion easier from high counter positions while maintaining productivity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The alignment system incorporates spatial distribution of alignment features along the load path rather than concentrating all alignment requirements at a single point. This dimensional distribution of alignment functions (first alignment feature, second alignment feature, load guide) reduces the difficulty of alignment from elevated positions by providing multiple opportunities for correct positioning.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If a load ramp with faceted surfaces is added to improve alignment, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:

Improvecassette alignment easeVSAvoidcassette station structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The load ramp is merged with the cassette station structure, and the alignment features are integrated into the existing components (alignment rod in the printhead assembly, engagement surfaces on the load ramp). This merging reduces overall device complexity by combining multiple functions into unified structures rather than adding separate independent components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The load ramp serves multiple functions: it guides the cassette along the load path, provides alignment surfaces for the first and second alignment features, and supports the cassette during insertion. This multi-functionality reduces the need for additional dedicated components, maintaining device complexity at acceptable levels while improving ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A printer includes a printer body including a cassette station, a printhead, and a media cassette for holding a media that moves past the printhead during printing. The media cassette is engageable in a loaded position in the cassette station and is removable from the cassette station for the purpose of media replacement. The printer body includes a load ramp extending outward from the cassette station, wherein the load ramp defines a linear load path for the media cassette and includes a first surface shape. The media cassette includes a cassette body and a load guide that that extends from the cassette body, wherein the load guide includes a second surface shape. The second surface shape is configured to mate with the first surface shape by overlying the first surface shape without surrounding the load ramp.
