Solution Overview

Problem

Existing bread slicers require user dexterity to bag sliced bread, leading to inefficiencies and the need for various bag formats, and can monopolize time in large-area settings due to manual packaging processes.

Innovation Solution

A compact bread slicer with a packaging system that uses two sheets of wrapping material, guided by arms and rollers, to automatically wrap and bind slices without the need for pre-formed bags, utilizing a holding member to keep slices together during movement and packaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual packaging with pre-formed bags is used, then packaging can be completed, but user dexterity is required and multiple bag formats must be stocked

Engineering Contradiction:
Improvepackaging format adaptabilityVSAvoidstock management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging member uses a single type of packaging material that can accommodate different bread formats and sizes through adjustable guide elements, eliminating the need for multiple pre-formed bag formats while maintaining versatility across different product types

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameters of the packaging approach by transitioning from fixed-size pre-formed bags to a continuous or semi-continuous packaging material with adjustable dimensions, allowing the same packaging system to handle various bread sizes without requiring multiple bag formats

Inventive Principle:
Principle #35Parameter changes

2Productivity

If manual slicing and bagging is performed, then bread can be packaged, but the process is slow and requires user dexterity

Engineering Contradiction:
Improvepackaging speedVSAvoiduser dexterity requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The holding member preliminarily gathers and positions the sliced bread into a compact bundle before the packaging operation, preparing the product in advance for automatic wrapping. This preliminary action eliminates the need for manual dexterity during the actual packaging process and significantly increases packaging speed

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system performs self-service packaging where the packaging member automatically wraps the bread slices without requiring manual intervention for bagging operations. The holding member and packaging member work together to automatically complete the packaging task, freeing the user from dexterity-intensive manual operations

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If a holding member is added to keep slices together, then slices remain organized during movement, but device complexity increases

Engineering Contradiction:
Improveslice arrangement stabilityVSAvoidslicer structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The holding member is merged with the existing slicer structure, integrating the slice-gathering function into the outfeed mechanism. By combining the holding function with the existing mechanical structure, the system maintains slice arrangement stability without proportionally increasing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If automated packaging with sheets is implemented, then packaging speed increases and compactness is achieved, but the mechanism complexity increases

Engineering Contradiction:
Improvepackaging automation speedVSAvoidpackaging mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The packaging mechanism is segmented into distinct functional components: the holding member for gathering slices, the packaging member with guide elements for positioning, and the wrapping execution system. This segmentation allows each component to be optimized independently while working together to achieve fast automated packaging in a compact form

Inventive Principle:
Principle #1Segmentation
