Solution Overview

Problem

Existing cube cutters for kitchen appliances require multiple steps for assembly and disassembly, leading to potential errors and safety risks, as users must manually ensure the correct positioning of snap-in fastening elements before use.

Innovation Solution

The integration of automatic locking elements on the cover of the cube cutter, which automatically lock the fastening elements into place when the cover is attached, eliminating the need for manual locking and reducing the complexity of assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual locking of fastening elements is required, then assembly precision can be ensured, but assembly complexity and time increase

Engineering Contradiction:
Improveassembly precisionVSAvoidassembly complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The cover is designed with integrated locking elements that automatically engage with the fastening elements when the cover is attached to the cube cutter. The system performs the locking action itself during the attachment process, eliminating the need for separate manual locking operations. This self-service mechanism ensures precise assembly while reducing the number of user steps required.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking elements are pre-positioned on the cover such that when the cover is attached to the cube cutter, the locking action occurs automatically as part of the attachment process. The geometry of the locking elements and fastening elements is designed so that proper alignment during attachment naturally results in the locked state, performing the precision action in advance during assembly rather than requiring a separate step.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple assembly steps are required, then locking reliability can be ensured, but user-friendliness decreases

Engineering Contradiction:
Improvelocking reliabilityVSAvoiduser-friendliness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment and locking functions are merged into a single integrated action. When the user attaches the cover to the cube cutter, both the mechanical attachment and the locking of fastening elements occur simultaneously through the integrated locking elements on the cover. This combines multiple functions into one user action, maintaining reliability while significantly improving ease of operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system automatically performs the locking function during the attachment process without requiring separate user actions. The locking elements on the cover engage with the fastening elements automatically when the cover is properly positioned and attached, making the system self-sufficient and eliminating the need for multiple manual steps.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If manual positioning of fastening elements is required, then assembly accuracy can be ensured, but time consumption increases

Engineering Contradiction:
Improveassembly accuracyVSAvoidassembly time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The locking elements are pre-configured on the cover with specific geometries that guide the fastening elements into the correct positions during attachment. The design ensures that when the cover is attached, the locking action and positional alignment occur simultaneously and automatically, performing the precision positioning in advance during the attachment process rather than requiring separate manual adjustment steps.

Inventive Principle:
Principle #10Preliminary action
