Solution Overview

Problem

Conventional transducer-type liquid sprayers face issues with solid components and impurities accumulating in the storage tank, making it difficult to replace the liquid storage tank and core, which affects the sprayer's performance over time.

Innovation Solution

A liquid sprayer design featuring a spray liquid storage unit with a core that soaks up liquid externally and a main body with a lid member that can be easily opened and closed, allowing for easy detachment and replacement of the storage unit, where the transducer is fixed to a support arm and in close contact with the core's front face, facilitating easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the liquid storage tank is detached from the liquid retaining body and only the storage tank is attached and detached to add spray liquid, then the spray liquid can be refilled, but solid components and impurities accumulate in the liquid retaining body over time making it unable to absorb spray liquid effectively

Engineering Contradiction:
Improveease of refillingVSAvoidabsorption effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The liquid retaining body is segmented into multiple detachable cores that can be individually removed and replaced. Each core is a separate absorbent component that can be independently maintained, allowing users to replace only the saturated core rather than the entire liquid retaining body, thus maintaining absorption effectiveness while keeping the system simple to refill.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the liquid retaining body is housed in an L-shaped casing, then the structure is compact, but the liquid retaining body is difficult to detach from the casing and is not easy to replace

Engineering Contradiction:
Improvecasing compactnessVSAvoiddetachability
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The liquid retaining body is divided into multiple separate cores that can be individually accessed and removed through the casing opening. This segmentation allows each core to be detached independently without requiring removal of the entire L-shaped casing, maintaining compact housing while enabling easy replacement of individual absorbent components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cores are designed to be extractable from the L-shaped casing through a dedicated opening. The cores can be removed individually from the casing without dismantling the casing structure itself, allowing easy replacement of the absorbent material while maintaining the compact housing design.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the transducer is fixed to the core, then the transducer maintains contact with the core, but the transducer cannot be easily detached for maintenance when the lid is opened

Engineering Contradiction:
Improvecontact maintenanceVSAvoidtransducer accessibility
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The system is segmented into distinct functional modules: the core (absorbent component), the transducer (ultrasonic component), and the lid assembly. The transducer is mounted on the lid assembly rather than being fixed to the core, allowing independent access to each component. This modular segmentation enables easy detachment of the transducer for maintenance while ensuring reliable contact with the core during operation through the pressing mechanism in the lid.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lid assembly incorporates a pressing mechanism that dynamically maintains contact between the transducer and the core. When the lid is closed, the pressing mechanism applies force to ensure the transducer remains in contact with the core for effective operation. When the lid is opened for maintenance, the contact is naturally released, allowing easy detachment of the transducer without permanent fixation.

Inventive Principle:
Principle #15Dynamics

AI summary

A liquid sprayer (1) comprising a spray liquid storage unit (5) and a main body for supporting the spray liquid storage unit inside itself. The spray liquid storage unit includes a core (34) for soaking up spray liquid stored in a storage tank to an outside of the storage tank. The main body includes a lid member (2) to be put on a support member (3) for supporting the spray liquid storage unit so that the lid member can be opened and closed. A spray hole (8) is formed in a position of the lid member facing a front face of the core of the spray liquid storage unit supported by the support member when the lid member is closed onto the support member, a transducer (44) facing the spray hole is disposed inside the lid member, and the transducer disposed inside the lid member is in close contact with and pressed against the front face of the core of the spray liquid storage unit supported by the support member when the lid member is closed onto the support member.
