Solution Overview

Problem

Typical dishwasher racks are rigid and inflexible, making it difficult to securely hold articles of varying shapes and sizes while allowing for easy rearrangement during the wash cycle.

Innovation Solution

A strap assembly with elongated resilient members and spherical ends that can be securely attached to the rack, allowing for adjustable positioning and secure retention of articles through various orientations and configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If rigid fixed retention devices are used in dishwasher racks, then articles can be secured in position, but the rack lacks adaptability to accommodate articles of different shapes and sizes

Engineering Contradiction:
Improveadaptability to accommodate different articlesVSAvoidcomplexity of retention device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The retention device incorporates a resilient member that can dynamically adjust its position and configuration along the rack structure. This elastic element allows the device to adapt to different article shapes and sizes while maintaining securing functionality, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retention device utilizes changes in the resilient member's physical state (compressed, extended, relaxed) to achieve different retention configurations. By changing the parameter of the resilient member's deformation state, the device can accommodate various article dimensions without requiring complex adjustable mechanisms.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If rigid fixed retention devices are used to secure articles, then articles are held firmly, but the devices are difficult to rearrange for adjustability

Engineering Contradiction:
Improveease of rearrangementVSAvoidsecurity of article retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The resilient member provides dynamic adjustment capability, allowing users to easily reposition retention devices by simply compressing or extending the elastic element. The device maintains reliable article security during normal operation but becomes easily adjustable when force is applied to the resilient member, resolving the contradiction between ease of rearrangement and retention reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The resilient member automatically returns to its original position after being compressed or extended, providing self-centering and self-locking functionality. This eliminates the need for complex adjustment mechanisms while maintaining both ease of operation and reliable retention, as the elastic force naturally secures articles when the device is in its resting state.

Inventive Principle:
Principle #25Self-service

3Productivity

If fixed retention devices are used, then articles are secured in predetermined positions, but the rack cannot be easily reconfigured during the wash cycle

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidflexibility to rearrange articles
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The resilient member enables dynamic reconfiguration of article positions during the wash cycle. Users can quickly adjust the retention device by manipulating the elastic element, allowing the rack to adapt to different loading requirements while maintaining productive cleaning operation throughout the cycle.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retention device changes its physical configuration through compression and extension of the resilient member, enabling rapid repositioning without requiring disassembly or complex adjustment mechanisms. This maintains high cleaning productivity while providing the flexibility to accommodate different article arrangements.

Inventive Principle:
Principle #35Parameter changes
