Solution Overview

Problem

Swimming pool equipment, such as chlorinators and heat pumps, consume excessive energy due to continuous operation, leading to energy waste and high operating costs, particularly exacerbated by the development of algae and bacteria accelerated by water heating and photosynthesis.

Innovation Solution

A two-mode control system that utilizes a covering element (shutter or pool cover) to detect its configuration and adjust the operation of swimming pool equipment accordingly, switching between standby and optimal efficiency modes based on the cover's position, using detection waves or light intensity measurements to send control signals for energy-efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If swimming pool equipment operates continuously to maintain water quality, then water treatment effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvewater treatment effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts equipment operation modes based on real-time detection of cover position. The control unit switches between first operating mode (reduced power) and second operating mode (normal power) according to whether the cover is deployed or retracted, making the system adaptive rather than static

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The detection device provides continuous feedback about the cover's configuration to the control unit. This feedback loop enables the system to automatically adjust equipment operation in response to cover position changes, ensuring water treatment effectiveness is maintained only when necessary

Inventive Principle:
Principle #23Feedback

2Reliability

If swimming pool equipment operates at full power to prevent algae and bacteria development, then water quality is improved, but operating costs increase

Engineering Contradiction:
Improvewater qualityVSAvoidoperating costs
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system uses periodic detection of cover position to determine when full-power operation is necessary. When the cover is deployed, equipment operates at reduced power; when retracted, full power is restored, creating a periodic operation pattern that reduces overall energy consumption while maintaining water quality

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control unit changes the operating parameters of the equipment based on cover position. Power consumption is reduced to a first level when covered and maintained at a second level when uncovered, directly linking parameter adjustment to the cover's configuration state

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If the cover element is deployed to reduce photosynthesis and heating, then energy waste from algae growth is reduced, but water treatment equipment must still operate effectively

Engineering Contradiction:
Improveenergy waste from photosynthesisVSAvoidwater treatment effectiveness
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

When the cover is deployed, the system applies partial action by reducing equipment power to a first operating mode rather than shutting it down completely. This partial operation is sufficient to maintain water quality when photosynthesis is blocked by the cover, avoiding excessive energy consumption

Inventive Principle:
Principle #16Partial or excessive action
