Solution Overview

Problem

Conventional dishwashers are unable to accommodate extraordinarily large dishes due to limited space between baskets and spray arms, preventing the insertion of items like platters or baking plates.

Innovation Solution

The dishwasher features a basket that can be arranged in both standard and upside-down orientations, allowing for increased space and a rotatable spray arm that adapts its position to ensure effective washing, with flexible connections to the water supply and adjustable fastening elements for optimal loading configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If baskets are arranged in standard orientation with spray arms below bottom grids, then washing coverage is maintained, but space for inserting large dishes is insufficient

Engineering Contradiction:
Improvespace for inserting dishesVSAvoidwashing coverage
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The basket is designed to be rotatable between standard and upside-down orientations, allowing dynamic reconfiguration of the washing space. This enables the same physical structure to provide different volume configurations depending on the loading requirements, solving the contradiction between space availability and washing coverage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention allows the basket to be inverted (upside-down orientation) to fundamentally change the spatial arrangement. By inverting the basket, the space below becomes available for large dish insertion while the spray arm repositioning maintains washing functionality, directly addressing the space limitation problem.

Inventive Principle:
Principle #13The other way round (Inversion)

2Volume of moving object

If spray arm is fixed below the bottom grid of the basket, then washing function is maintained, but space below the basket is limited

Engineering Contradiction:
Improvespace below basketVSAvoidwashing function
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The spray arm is designed with rotational capability to move between positions below the bottom grid (standard orientation) and above the bottom grid (upside-down orientation). This dynamic repositioning ensures the spray arm maintains functional proximity to the basket in both orientations, preserving washing reliability while enabling space expansion.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spray arm assembly is designed to perform the washing function effectively in both standard and upside-down basket orientations. By making the spray arm multi-position capable, the system achieves universal washing functionality regardless of basket orientation, allowing the same hardware to serve multiple spatial configurations.

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

3Adaptability or versatility

If basket structure is fixed in standard orientation, then manufacturing is simple, but adaptability for different dish sizes is limited

Engineering Contradiction:
Improveloading flexibilityVSAvoidbasket configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The basket incorporates rotational capability to switch between standard and upside-down orientations, providing dynamic adaptability for different dish loading configurations. This mechanical flexibility allows the same basket structure to accommodate various dish sizes and types without requiring multiple specialized baskets, achieving versatility with minimal added complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The basket design achieves multi-functionality by being usable in both standard and upside-down orientations. This universal design allows a single basket structure to serve multiple purposes: accommodating small dishes in standard orientation and large dishes in upside-down orientation, thereby increasing loading flexibility without proportionally increasing device complexity.

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