Solution Overview

Problem

Conventional spray devices for aromatic agents have limited opening mechanisms, making it difficult to clearly see the coupling status of canisters, which complicates quick and single-operation replacement.

Innovation Solution

A quick-mounting device with a housing and adjustment means featuring arched pieces and a control piece with springs, allowing for a complete opening by pressing the pusher to move the arched pieces outward, enabling easy mounting and dismounting of canisters without visualizing the clamping status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hinged clamp is used to clamp a canister neck, then the canister can be secured for spraying, but the clamp cannot be opened more than 60 degrees making it difficult to see the coupling status

Engineering Contradiction:
Improvecanister securingVSAvoidcoupling status visibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The clamp is divided into two arched pieces that can move independently relative to each other, allowing the opening angle to exceed 60 degrees while maintaining secure clamping. The control piece segments the operation into distinct phases: pushing the control piece moves both arched pieces simultaneously to achieve full opening for visibility, while releasing allows spring-driven return to clamping position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clamp mechanism transitions from a single-plane hinged motion to a multi-dimensional movement where the two arched pieces can diverge in opposite directions. This dimensional change allows the opening angle to exceed the conventional 60-degree limit while maintaining structural integrity and secure clamping force through the spring mechanism.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the clamp opening is limited to about one half, then the structure remains simple, but the user cannot clearly see the coupling status of the canister

Engineering Contradiction:
Improveclamp structureVSAvoidcoupling status detection
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The clamp employs dynamic movement of the two arched pieces that can diverge independently when the control piece is pushed. This dynamic mechanism allows the opening to expand beyond the static one-half limitation, providing full visibility of the coupling status while maintaining structural simplicity through the spring-loaded return mechanism that automatically resets the clamp.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If conventional clamps are used, then manufacturing is simple, but replacement of canisters cannot be accomplished in one operation

Engineering Contradiction:
Improveclamp manufacturingVSAvoidcanister replacement speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The clamp mechanism is pre-configured with two arched pieces and spring elements that are already positioned to enable one-operation replacement. When the control piece is pushed, the pre-loaded springs immediately drive the arched pieces to diverge, automatically releasing the canister without requiring additional manual steps. This preliminary arrangement of components allows rapid canister replacement while maintaining simple manufacturing processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The clamp mechanism rushes through the canister release process by using spring energy to quickly diverge the two arched pieces when the control piece is pushed. This rapid movement skips intermediate adjustment steps, allowing the canister to be released in one operation rather than requiring multiple manual adjustments, thereby increasing productivity while keeping the manufacturing process simple.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

A quick-mounting device (1) for canisters comprises a housing (11) and an adjustment means (12). The housing defines a recess (112) at a top thereof and a hollow space therein (111). The housing is sealed with a cover (117) that defines a though hole at a center thereof. The adjustment means includes two arched pieces (124) and a control piece (121). The control piece has a pusher (122) and is placed on top of the arched pieces to engage with two ends of each arched piece. Thereby, the pusher of the control piece can be pressed to have the two arched pieces moved outwardly to change the dimension of the opening defined by the two arched pieces so as to mount a canister.
