Solution Overview

Problem

Existing oil spray devices require a complex process and high costs due to the use of different materials with distinct springback properties for the trigger and arcuate arm, and the dome valve structure is prone to malfunctions in oil dispensing.

Innovation Solution

An oil spray bottle design with a trigger protrusion made of the same material as the handle, synchronizing its motion with the handle, and a piston structure inside the atomizing nozzle that opens and closes the oil outlet channel under oil pressure, using springs for reliable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different materials with distinct springback properties are used for the trigger and arcuate arm, then the springback capability is improved, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improvespringback capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the trigger and arcuate arm into a single integral structure, eliminating the need for separate components with different materials. This merging approach maintains the required springback capability while significantly simplifying the manufacturing process and reducing costs, as no special molds or multi-material injection processes are needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent modifies the physical parameters of the integral trigger structure by optimizing its geometric shape and thickness distribution to achieve the necessary springback characteristics. Through parameter optimization rather than material differentiation, the design attains reliable elastic deformation and recovery while using a single material system.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If a dome valve structure is used for oil dispensing, then the oil outlet control is achieved, but the reliability and resistance to malfunction decrease

Engineering Contradiction:
Improveoil outlet controlVSAvoidresistance to malfunction
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts and eliminates the dome valve component from the system, replacing it with a direct piston-driven oil outlet mechanism. This removal of the problematic dome valve structure eliminates the inherent malfunctions associated with dome valve springback failures, while the oil outlet control function is maintained through the piston's direct mechanical action.

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If an integral arcuate arm structure is used for trigger springback, then the structural strength is improved, but the manufacturing cost and process complexity increase

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The trigger and arcuate arm are merged into a single molded component, which maintains the structural strength benefits of the integral arcuate design while eliminating the high manufacturing costs associated with multi-material injection molding and special molds. The unified structure can be produced more efficiently using standard molding processes.

Inventive Principle:
Principle #5Merging (Combining)
