Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction machines for conveying thick materials face challenges in efficiently removing adhering materials during operations, which can lead to reduced efficiency and increased maintenance needs.
Innovation Solution
The construction machine is equipped with a cleaning device that includes a support structure and an adjustable nozzle carrier with multiple nozzle devices, allowing for thorough cleaning of the machine's interior and components using a cleaning fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cleaning device with fixed nozzle positioning is used, then the cleaning operation is simple, but the cleaning effectiveness is insufficient for thorough removal of adhering thick material
Solution Approach 1:
The nozzle carrier is made adjustable relative to the support structure, allowing the nozzles to be repositioned to different locations and angles. This dynamic positioning capability enables thorough cleaning of various surfaces including the storage container interior and external components, resolving the contradiction between cleaning effectiveness and device simplicity by introducing controlled adjustability rather than complete complexity
2Area of stationary object
If multiple nozzles are added to cover all cleaning areas, then cleaning coverage is improved, but the consumption of cleaning fluid increases
Solution Approach 1:
The adjustable nozzle carrier allows a limited number of nozzles to be repositioned and reoriented to cover different cleaning areas sequentially or simultaneously as needed. This dynamic positioning enables comprehensive cleaning coverage without requiring a fixed array of nozzles for every possible surface, thereby reducing overall fluid consumption while maintaining thorough cleaning effectiveness
3Adaptability or versatility
If the cleaning device is integrated permanently into the construction machine, then the cleaning function is always available, but the machine complexity and cost increase
Solution Approach 1:
The cleaning device with its adjustable nozzle carrier is designed as a multi-functional unit that can clean various parts of the construction machine including the storage container interior, external surfaces, and components. This universal cleaning capability is achieved through a relatively simple adjustable structure rather than multiple dedicated cleaning systems, resolving the contradiction between versatility and complexity
