Direction-controllable sprinkler with independent trigger control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinklers have limitations in controlling sprinkling directions due to single or dual trigger switches that require multiple triggers for symmetrical adjustments, making them inconvenient to use.
Innovation Solution
A single or dual sided direction-controllable sprinkler design featuring rotatable trigger portions with adjustable slant guiding openings and a fastener mechanism that allows independent or synchronized control of sprinkling directions through the use of slant guiding openings and a cover with direction guiding holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single trigger switch is used to control sprinkling direction, then the device structure is simple, but the control flexibility is limited and cannot achieve both outward and upward sprinkling directions simultaneously
Solution Approach 1:
The single trigger switch is segmented into two independent trigger switches, each controlling a separate trigger portion. This allows independent control of outward and upward sprinkling directions, resolving the contradiction between structural simplicity and control flexibility by dividing the control function into two manageable parts.
Solution Approach 2:
The trigger portions are made rotatable relative to the main body, allowing dynamic adjustment of sprinkling directions. This dynamic capability enables the sprinkler to switch between different spraying patterns (outward, upward, or both simultaneously) while maintaining a relatively simple overall structure.
2Adaptability or versatility
If two trigger switches are used to control sprinkling directions on two sides, then the sprinkling direction control is improved, but the operation becomes inconvenient requiring two triggers for symmetrical adjustments
Solution Approach 1:
Two trigger switches are merged into a single integrated trigger mechanism that can simultaneously control both trigger portions. This merging allows symmetrical adjustments to be made with a single operation, resolving the contradiction between versatile direction control and operational convenience.
Solution Approach 2:
A fastener is introduced as an intermediary component that couples the two trigger portions together. When engaged, the fastener ensures both trigger portions move synchronously, providing a mechanical mediator that simplifies operation while maintaining precise directional control capability.
3Measurement precision
If the two trigger portions are adjusted independently, then the sprinkling direction precision is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The trigger portions are designed to be rotatable with adjustable positions, providing dynamic precision control without complex mechanisms. Each trigger portion can be independently positioned to achieve precise sprinkling directions while maintaining structural simplicity through the rotatable design.
Solution Approach 2:
The trigger portions serve multiple functions: they can be adjusted independently for precise directional control, or coupled together via the fastener for symmetrical adjustments. This multi-functionality reduces the need for separate control mechanisms for different operating modes.
4Ease of operation
If the fastener is used to fix the two trigger portions, then the operational convenience is improved by enabling synchronous adjustment, but the adaptability decreases as independent control is limited
Solution Approach 1:
The fastener is designed to be selectively engageable and disengageable, allowing the system to dynamically switch between coupled (synchronous) and uncoupled (independent) modes. This dynamic configuration resolves the contradiction by providing both operational convenience and adaptability as needed.
Solution Approach 2:
The system changes its control parameters by engaging or disengaging the fastener. When engaged, the trigger portions move together with synchronized parameters; when disengaged, they operate with independent parameters. This parameter change capability allows the system to adapt to different operational requirements.

AI summary
A single or dual sided direction-controllable sprinkler comprises two rotatable trigger portions slidably disposed on a main body. When one trigger portion is limited by a fastener, the two trigger portions have the same rotational position, and when the one trigger portion is not limited by the fastener, the rotational positions of the two trigger portions are controlled independently. The fastener is selectively connected to allow the user to selectively control one of the trigger portions or both of the trigger portions together so that various water sprinkling modes are available.
