Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pressurized oil spray bottles suffer from a decrease in rebound force over time due to trigger aging, leading to residual oil accumulation at the nozzle, which can contaminate the trigger and affect usage.

Innovation Solution

The pressurized oil spray bottle incorporates a double-torque spring and an oil receiving box, ensuring consistent rebound force and directing residual oil into an oil groove, preventing contamination and facilitating cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional trigger structure is used, then the device is simple to manufacture, but the rebound force decreases over time due to aging

Engineering Contradiction:

Improverebound force consistencyVSAvoidtrigger structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a double-torque spring mechanism that dynamically compensates for trigger aging. The spring maintains consistent rebound force through its mechanical properties, allowing the trigger to return to its initial state after each press regardless of usage duration, thus resolving the contradiction between reliability and device complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The double-torque spring changes the physical parameters of the trigger system by providing a controlled elastic force that counteracts aging effects. This parameter change ensures the rebound force remains constant over time, addressing the reliability issue without requiring complex electronic or mechanical control systems.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If the nozzle opening is exposed, then spraying function is achieved, but residual oil flows onto the trigger causing contamination

Engineering Contradiction:

ImprovecleanlinessVSAvoidresidual oil contamination

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful residual oil from the trigger area by providing a dedicated drainage path. The oil groove and drainage hole separate the contaminant (residual oil) from the trigger, allowing it to drain away from the trigger mechanism, thus maintaining cleanliness without compromising the spraying function.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The oil groove acts as an intermediary element between the nozzle opening and the trigger. It captures and channels residual oil away from the trigger, serving as a mediator that prevents direct contact between the contaminant and the trigger, thereby resolving the contamination issue.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If spraying time is extended, then more oil is dispensed, but residual oil accumulation increases

Engineering Contradiction:

Improveoil dispensing efficiencyVSAvoidresidual oil waste

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent converts the harmful effect of residual oil accumulation into a beneficial drainage system. The oil groove and drainage hole transform the waste problem into a controlled flow path, allowing residual oil to be efficiently removed through gravity-driven drainage, thus reducing waste without affecting productivity.

Inventive Principle:

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