Solution Overview

Problem

Existing container dividing devices for refrigerated goods in freezers are difficult to assemble and disassemble quickly, leading to unnecessary heat and moisture flow, which complicates interior layout changes.

Innovation Solution

A container with a dividing device featuring a clip that secures a bolt with a projection extending from the partition wall, using a bolt with a head piece, crossbar, and shaft for locking, and a bracket with symmetrical legs and latching contours to prevent rotation, allowing for easy assembly and disassembly while maintaining childproof safety and minimizing weight while maximizing rigidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a dividing device is designed to be easily assembled and disassembled for layout changes, then the ease of operation is improved, but the secure fastening and structural stability may be compromised

Engineering Contradiction:
Improveease of assembly and disassemblyVSAvoidsecure fastening
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The bolt is designed with a rotatable crossbar that transitions between a passage orientation (for easy insertion) and a locking orientation (for secure fastening). This dynamic element allows the same component to serve both assembly convenience and structural reliability functions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bracket features asymmetrical design with one leg having an opening for bolt insertion and the other leg providing structural support. This local differentiation optimizes each part for its specific function while maintaining overall system reliability and ease of assembly.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If the head of the bolt is made large for easy manual operation, then the ease of operation is improved, but it impedes the placement of refrigerated goods in the basket

Engineering Contradiction:
Improveease of bolt rotationVSAvoidspace available for goods
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

A tool such as a screwdriver or coin is introduced as an intermediary to rotate the bolt head. This allows the bolt head to remain small and non-obtrusive while still providing adequate leverage for operation through the tool interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If the dividing wall is made thick for high rigidity, then the strength is improved, but the weight of the dividing wall increases

Engineering Contradiction:
Improverigidity of dividing wallVSAvoidweight of dividing wall
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The dividing wall combines a thin base structure with strategically placed thicker regions (edge beads) and reinforcement elements. This composite approach achieves high rigidity where needed while minimizing overall weight through selective thickening rather than uniform increase.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The edge bead is made thicker than the distance between the legs of the bracket at specific locations to provide localized reinforcement. This local quality enhancement achieves the required rigidity only where structurally necessary, reducing overall weight compared to a uniformly thick wall.

Inventive Principle:
Principle #3Local quality

4Reliability

If the bracket is designed with complex fastening mechanisms for secure attachment, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvesecure attachment of bracketVSAvoidcomplexity of fastening mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bolt integrates multiple functions into a single component: the shaft provides the fastening element, the crossbar provides the locking mechanism through rotation, and the head provides the interface for tool operation. This merging reduces the number of separate parts while maintaining secure attachment reliability.

Inventive Principle:
Principle #5Merging (Combining)
