Solution Overview

Problem

Weather-related delays, particularly due to rain, frequently disrupt construction and landscaping projects as exposed dirt quickly turns to mud, causing operational inefficiencies and additional costs, with existing mitigation methods like water pumps and plastic sheeting being ineffective.

Innovation Solution

Spreading superabsorbent granules, such as potassium polyacrylate or sodium polyacrylate, over the area before precipitation to absorb falling rainwater, either as loose granules or within an application bag, allowing immediate resumption of activities once the rain stops and the granules are removed or dried for reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If water pumps and plastic sheeting are used to mitigate rain, then some protection is provided, but they are ineffective and do not prevent mud formation

Engineering Contradiction:
Improveeffectiveness of rain mitigationVSAvoidconstruction work continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The superabsorbent granules are applied to the ground before rain occurs, creating a protective layer that is ready to absorb precipitation immediately when it falls. This preliminary action prevents the granules from becoming saturated before they can perform their protective function, ensuring reliable mud prevention from the start of rainfall.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the physical and chemical parameters of the ground surface by applying a layer of superabsorbent granules with specific absorbency characteristics. These granules have high water absorption capacity and can absorb hundreds of times their weight in water, fundamentally altering how the ground interacts with rainfall and preventing mud formation.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If plastic sheeting is used to cover exposed dirt, then rain protection is attempted, but the sheeting gets blown off and fails to protect the area

Engineering Contradiction:
Improverainwater contact with dirtVSAvoidprotection effectiveness
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The superabsorbent granules act as an intermediary substance between the rainwater and the exposed dirt. Instead of trying to physically block rain with plastic sheeting that can be blown away, the granules chemically and physically absorb the rainwater, preventing it from reaching the dirt and causing mud formation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces the mechanical barrier approach (plastic sheeting that relies on physical coverage and anchoring) with a chemical absorption approach (superabsorbent granules that absorb water through osmotic pressure and hydrogel expansion). This substitution eliminates the reliability issues associated with mechanical barriers being blown off or failing to cover all areas.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If water pumps are used to remove standing water, then some water removal is achieved, but the exposed dirt quickly turns to mud with nothing that can be done except to wait

Engineering Contradiction:
Improvestanding water removalVSAvoiddrying time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The superabsorbent granules perform preliminary anti-action by absorbing rainwater before it can saturate the ground and create mud. This prevents the harmful condition (mud formation) from occurring in the first place, eliminating the need for water pumps and the subsequent waiting period for drying.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The invention converts the harmful effect of rainwater (which causes mud formation and construction delays) into a beneficial process by using superabsorbent granules to control and manage the water absorption. The granules absorb the water that would otherwise be harmful, transforming the problem of excess water into a controlled absorption process that prevents mud while allowing work to continue.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Object-affected harmful factors

If a layer of superabsorbent granules is spread over the area, then rainwater is absorbed before reaching the ground, but the granules need to be removed or dried for reuse

Engineering Contradiction:
Improverainwater absorptionVSAvoidgranule management process
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The superabsorbent granules are applied to the ground, perform their water absorption function during rainfall, and then are collected and dried for reuse. This recovery process allows the same granules to be used multiple times, reducing waste and operational costs while maintaining effective rain protection.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The superabsorbent granules are designed to be reusable after drying, creating a self-sustaining system where the same material can serve multiple protection cycles. This reduces the need for continuous application of new materials and minimizes waste, making the rain protection system more sustainable and cost-effective over time.

Inventive Principle:
Principle #25Self-service

AI summary

A method of absorbing falling precipitation to prevent the falling precipitation from reaching an area for an activity includes spreading a sufficient amount of a water absorbent including superabsorbent granules over the area prior to or during the falling precipitation so that the superabsorbent granules can absorb the water before the falling precipitation can reach the area wherein the activity can immediately occur after the falling precipitation stops and the water absorbent is removed. Another method of absorbing falling precipitation to prevent the falling precipitation from reaching an area for an activity includes placing an application bag over the area prior to or during the falling precipitation, wherein the application bag includes a sufficient amount of superabsorbent granules inside a casing, wherein the superabsorbent granules can absorb the falling precipitation before the falling precipitation can reach the area, and wherein the activity can immediately occur after the falling precipitation stops and the application bag is removed.
