Solution Overview

Problem

Current cooling device basket handles are inefficient in supporting weight and facilitating easy transportation due to their design, which relies solely on horizontal wires and has limited load-carrying capacity, especially when stacking multiple baskets.

Innovation Solution

The handle is designed to rotate around a horizontal wire, passing through parallel horizontal wires and incorporating slits and projections to support the basket's vertical wires, allowing it to grasp a wider surface area for better weight distribution and secure stacking, enabling safer and easier handling of baskets at both hanging and stacking positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the handle is designed to rotate around a horizontal wire and pass through parallel horizontal wires, then the load-carrying capacity is improved, but the device complexity increases

Engineering Contradiction:
Improveload-carrying capacityVSAvoidhandle structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The handle is designed to be rotatable around a horizontal wire, transitioning between a first position for supporting the basket weight and a second position for facilitating removal. This dynamic positioning allows the same handle structure to serve multiple functions: providing structural support when rotated to the first position and enabling easy basket removal when rotated to the second position, thereby improving load-carrying capacity without permanently increasing device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle structure incorporates both a bearing surface for supporting basket weight and a grasping function for basket removal. By integrating these two functions into a single handle component that can rotate between positions, the invention achieves multi-functionality, improving load-carrying capacity while avoiding the need for separate support and removal mechanisms

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

2Ease of operation

If the handle leans against vertical wires and grasps horizontal wires, then the ease of operation is improved, but the reliability decreases due to limited contact area

Engineering Contradiction:
Improvebasket transportationVSAvoidhandle attachment security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The handle design transitions from relying solely on horizontal wire contact to incorporating vertical wire contact as well. The handle is configured to lean against vertical wires while also grasping horizontal wires, adding a vertical dimension to the contact geometry. This multi-dimensional contact approach increases the contact area and distribution points, thereby improving reliability while maintaining ease of operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The handle incorporates a bearing surface with increased contact area that is specifically positioned to contact the horizontal wire. This localized quality improvement at the critical contact point enhances the reliability of the attachment, while the overall handle structure maintains its ease of operation characteristics

Inventive Principle:
Principle #3Local quality
