Ergonomic Spray Bottle Appendage for Hand Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger pump dispensers often lead to hand fatigue and accidental slippage due to inadequate ergonomic design, limiting their use over extended periods without providing effective support for the weight and proper alignment during handling.
Innovation Solution
A container appendage with a mounting ring and platform member that integrates with the bottle and spray body, featuring ergonomic handling members to conform to the hand, distribute load, and improve grip, allowing for longer use without fatigue and reducing slippage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional trigger pump dispenser is used without ergonomic enhancements, then the device structure remains simple, but hand fatigue occurs and grip stability deteriorates during prolonged use
Solution Approach 1:
The handle is segmented into multiple functional zones including a grip portion with ergonomic contouring, a trigger mechanism, and a platform member with lifting protrusion. This segmentation allows each zone to perform its specific function optimally while contributing to overall ergonomic improvement without requiring complete redesign of the entire device
Solution Approach 2:
Ergonomic features such as the contoured grip portion, recessed trigger, and lifting protrusion are applied locally to specific areas of the handle where they are most needed. The grip portion is specifically shaped to conform to hand anatomy, the trigger is recessed to facilitate finger engagement, and the lifting protrusion is positioned to enable thumb activation. This localized application of ergonomic enhancements improves handling without unnecessarily complicating the entire device structure
2Duration of action of moving object
If the trigger pump dispenser is designed for extended use, then user comfort improves, but the risk of accidental slippage increases without proper grip support
Solution Approach 1:
The grip portion of the handle is contoured with curved surfaces that conform to the natural shape of the user's hand. This curvature creates multiple contact points between the hand and the handle, increasing friction and preventing slippage during prolonged use. The ergonomic contouring maintains consistent grip pressure distribution, reducing fatigue and maintaining reliability over extended periods
3Ease of operation
If the trigger pump dispenser provides weight support, then finger strain is reduced, but the device requires additional structural components
Solution Approach 1:
The lifting function is merged with the existing handle structure by incorporating a lifting protrusion as an integrated feature of the platform member. This lifting protrusion works in conjunction with the user's thumb to bear the weight of the dispenser, eliminating the need for separate support structures or additional mechanical components. The integration of weight support functionality into the handle design achieves ergonomic improvement without proportionally increasing device complexity

AI summary
A container appendage is disclosed comprising a mounting ring having an upper surface, a lower surface, an exterior edge and an interior edge for defining a mounting aperture. A platform member is coupled to the mounting ring. The mounting ring is coupled between the bottle and the spray body for defining a mounting ring couple. The platform member cantilevers above the handling neck and adjacent to the rear surface for defining a rear ergonomical handling member for conforming to the hand and improving ergonomical grasping of the handling neck, actuating the trigger and lifting the spray bottle by the hand.
