Foldable Handle Trigger Texture Dispensing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid spray dispensers are unsuitable for spraying texture materials onto ceilings or surfaces directly above the user due to ergonomic limitations and are prone to damage when used at non-standard orientations, leading to ineffective actuation of the valve and potential harm to the dispenser's fluidics.
Innovation Solution
A texture material dispensing system with a foldable handle and trigger that pivots to create an ergonomic applicator, allowing for efficient spraying onto ceilings by altering the valve configuration from a closed to an open state when the trigger is depressed, maintaining the can in an upright position and preventing accidental actuation in a non-use position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional spray dispensers are used to spray onto ceilings, then the target surface can be accessed, but the dispenser cannot be effectively actuated due to orientation issues and may suffer damage to fluidics
Solution Approach 1:
The handle is made pivotable relative to the container assembly, allowing the user to dynamically adjust the handle orientation to ergonomic positions while keeping the container upright. This dynamic adjustment enables effective trigger actuation for ceiling spraying without compromising the container's orientation or fluidic integrity.
2Volume of moving object
If the handle is made foldable, then storage and shipping space is reduced, but the mechanism for actuation becomes more complex
Solution Approach 1:
The handle incorporates a pivot joint that allows it to fold against the container body for compact storage and shipping. The pivot mechanism is integrated into the existing actuator assembly, adding minimal complexity while enabling the handle to transition between extended (spraying) and folded (storage) positions.
3Ease of operation
If the trigger is made pivotable, then ergonomic positioning is improved, but the actuation mechanism becomes more complex
Solution Approach 1:
The trigger is attached to the handle via a pivot connection, allowing it to move dynamically with the handle to maintain ergonomic positioning. The pivot mechanism is integrated into the actuator assembly, enabling the trigger to follow the handle's motion while maintaining proper actuation geometry.
Solution Approach 2:
The trigger pivot mechanism is merged with the handle pivot mechanism, sharing common pivot points and structural elements. This integration reduces overall complexity by combining multiple functions into a unified mechanical system rather than adding separate mechanisms.
