Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of dishwashers is compromised due to flow velocity loss and water pressure drop when the direction of washing water changes within the alternating device, leading to a deterioration in washing performance.
Innovation Solution
The alternating device includes a rotatable distributor with a curved guide and multiple outflow portions, which directs washing water efficiently to multiple spray units, minimizing flow velocity loss and maintaining water pressure by guiding water through a curved surface where the flow direction changes, thereby enhancing the distribution of washing water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If washing water is distributed to different directions inside the alternating device, then multiple spray units can be supplied, but flow velocity loss occurs resulting in deterioration of efficiency
Solution Approach 1:
The patent employs curved guide surfaces and arc-shaped flow paths within the alternating device to smoothly redirect washing water to multiple spray units. The curved geometry eliminates sharp angles and sudden direction changes, maintaining flow velocity and preventing turbulence while distributing water to multiple outlets simultaneously.
2Ease of operation
If the flow direction of washing water changes, then water can reach different spray units, but flow velocity loss occurs
Solution Approach 1:
The alternating device incorporates curved guide surfaces that smoothly transition water flow between different directions. These curved paths eliminate sudden flow direction changes, maintaining kinetic energy and flow velocity while enabling water to reach multiple spray units effectively.
3Adaptability or versatility
If washing water is circulated to multiple spray units, then comprehensive washing is achieved, but water pressure drops
Solution Approach 1:
The patent utilizes curved flow paths and guide surfaces within the alternating device to minimize flow resistance and turbulence. The smooth curved geometry reduces energy loss during direction changes, maintaining water pressure while distributing water to multiple spray units simultaneously.
