Angled-Pump Suction Cup for Ergonomic Windshield Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction cups cause wrist sprain and potential injury to the waist or legs when used to mount or dismount non-horizontal objects like vehicle windshields, as they require awkward gripping or bending postures.
Innovation Solution
A suction cup design featuring a cup body with a pump and movable handle, where the pump is angled relative to the axial direction, allowing the handle to be gripped horizontally and reducing the need for flexing, thereby minimizing strain on the hands, knees, and waist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction cup is used to mount non-horizontal objects like vehicle windshields, then the suction cup can effectively hold the object, but the user must grip the handle with waist flexing downwardly, causing wrist sprain
Solution Approach 1:
The pump handle is extended along the axial direction of the cup body, creating a longitudinal dimension for force application. This allows the user to apply force in a straight line along the axis of the suction cup, rather than gripping at an awkward angle, thereby maintaining holding capability while improving ergonomic comfort
2Ease of operation
If the user grips the handle with waist flexing downwardly to mount the windshield, then the suction cup can be operated, but it causes wrist sprain easily
Solution Approach 1:
The pump handle is positioned and oriented such that the user can apply force horizontally at a comfortable height, creating an equipotential working position that eliminates the need for waist flexing or knee bending. This maintains operational capability while removing harmful postures that cause wrist and lower body strain
3Ease of operation
If the user slightly squats or flexes waist or legs to have a lower position, then wrist sprain can be avoided, but injury to waist or legs can occur
Solution Approach 1:
The pump handle extension along the axial direction allows the user to operate the suction cup from a standing position at a comfortable height. This eliminates the need to squat or flex legs, maintaining proper operational posture while preventing injury to the waist and legs
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and safe mounting or dismounting of windshields without causing harm to the hands, knees, or waist by allowing horizontal grip of the pump, reducing the risk of injury and improving operational comfort.
Implementation Method 1
a pump, connected to an end of the cup body opposite to the sucking face
Implementation Method 2
a movable handle, slidably disposed within the first passageway, including a piston
