Frost Compensator for Water Application Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watering equipment is prone to damage from frost expansion in pre-configured setups, as residual water in devices can expand and cause damage to internal components during freezing conditions, leading to equipment failure.
Innovation Solution
Incorporating compensators made of flexible, compressible materials into critical areas of the water application device to accommodate volumetric expansion of freezing water, allowing for repeated cycles without material degradation, thus protecting the device from frost and impulse damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water application device is left pre-configured for frequent use, then ease of operation is improved, but reliability deteriorates due to frost expansion damage
Solution Approach 1:
The compensator is installed in advance within the flow channel to provide cushioning against frost expansion. It absorbs the volumetric expansion of freezing water before the expansion can damage the spray nozzle or other components, thereby protecting the pre-configured device while maintaining ease of operation.
Solution Approach 2:
The compensator acts as an intermediary element between the freezing water and the vulnerable components of the water application device. It mediates the harmful expansion force, allowing the device to remain pre-configured and easy to operate while protecting against frost damage.
2Reliability
If compensator is added to protect against frost expansion, then reliability is improved, but device complexity increases
Solution Approach 1:
The compensator is constructed from a flexible material that can deform to accommodate water expansion. This flexible shell approach provides reliable protection against frost expansion while maintaining simplicity in design and installation, avoiding complex mechanical structures.
Solution Approach 2:
The compensator utilizes changes in the physical state and volume of water during freezing and thawing cycles. By allowing the compensator material to expand and contract with the freezing water, the system achieves reliable protection without adding complex control mechanisms or multiple components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The compensators effectively absorb and compensate for volumetric expansion, preventing damage to internal components and ensuring the device's durability and functionality even under repeated freezing conditions.
Implementation Method 1
residual water left in the equipment could expand with the freezing and damage the equipment
Implementation Method 2
the compensator may be compressed (i.e., undergoing volumetric contraction) to compensate for the volumetric expansion of the freezing water

AI summary
A water application device (10, 100) may include a main body (20, 110) graspable along a handle portion (22, 119) thereof by an operator, an operable member (30, 140), and a flow channel. The main body (20, 110) may house a flow control assembly (50) configured to enable the device to execute a control function relative to flow of water through the device. The operable member (30, 140) may be operably coupled to the main body (20, 110) to interface with the flow control assembly (50) to alternately provide flow and stop flow through the device. The flow channel may be formed inside the main body to define a flow path between an inlet portion (26, 114) and an outlet portion (24, 112) of the device. The flow channel may define at least one critical area in which water is enabled to collect when the water application device is not applying water. The critical area may include at least one compensator receiver (320) configured to receive a compensator (300) comprising compressible material configured to enable the compensator to be compressed within the critical area to increase an effective volume of the critical area. One of the compensator or the critical area may be provided with at least one retention rib (330, 340) to facilitate holding the compensator in the critical area.
