Solution Overview

Problem

Existing concrete delivery systems lack effective mechanisms to prevent concrete from splashing onto unintended objects during pouring, leading to inefficiencies and potential damage.

Innovation Solution

The anti-splatter device for concrete truck chutes, comprising a concrete comb, a mounting bracket, and a concrete chute, forms a protected space by combing the concrete as it is poured, preventing splashes from reaching unintended objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If concrete is poured through a standard chute, then concrete delivery speed is maintained, but concrete splashes onto unintended objects causing damage and cleanup requirements

Engineering Contradiction:
Improveconcrete splatter damageVSAvoidchute structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A comb-shaped barrier is introduced as an intermediary element between the concrete chute and the surrounding environment. This comb structure intercepts and redirects splashing concrete, preventing it from reaching unintended objects while allowing the main concrete flow to pass through unchanged.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective barrier is segmented into multiple vertical teeth or combs rather than using a solid continuous wall. This segmentation allows the barrier to effectively block splatter trajectories while maintaining visibility, allowing air flow, and not interfering with the main concrete delivery stream.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a protective barrier is added to prevent concrete splatter, then safety and cleanliness are improved, but the device complexity and installation requirements increase

Engineering Contradiction:
Improvesafety during concrete deliveryVSAvoidmounting bracket system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A mounting bracket system serves as an intermediary structure that connects the comb-shaped barrier to the existing chute. This bracket system provides a reliable attachment mechanism while being relatively simple in design, using standard mechanical fastening elements to secure the barrier in position.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The comb-shaped barrier is designed to be self-supporting once mounted, with its own structural integrity maintaining its protective function. The barrier does not require additional active components, motors, or complex control systems to operate - it passively performs its splatter prevention function through its geometric structure.

Inventive Principle:
Principle #25Self-service

AI summary

The anti-splatter device for use with a concrete truck chute is a protective structure. The anti-splatter device for use with a concrete truck chute incorporates a concrete comb, a mounting bracket, and a concrete chute. The concrete comb attaches to the mounting bracket. The mounting bracket secures the concrete comb to the concrete chute. The anti-splatter device for use with a concrete truck chute forms a protected space at the location where the concrete chute is delivering concrete. The concrete comb combs the concrete as the concrete is poured such that the concrete comb prevents the concrete from splashing on objects that are not designated to receive concrete.
