Door Handle Attachment for Sliding Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contemporary sliding doors, particularly those with mesh screens, are difficult to open and close due to recessed grips that are cumbersome, uncomfortable, and often lead to wear and tear on the doors, and are inaccessible for individuals with disabilities or varying heights.
Innovation Solution
A door handle attachment with a raised handle ridge that can be adhered to the door frame, providing a grip or force application point for easy opening and closing, designed to be symmetrical or asymmetrical, and made from various materials like galvanized aluminum or thermoplastic polymers, ensuring durability and compatibility with different door styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a recessed grip is used on sliding doors, then the door structure remains simple and compact, but the ease of operation deteriorates and wear and tear increases
Solution Approach 1:
The door handling system is segmented into two independent parts: the original door structure with recessed grip and the separate attachable handle ridge. This allows the handle ridge to be added without modifying the door structure, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The handle ridge acts as an intermediary element between the user and the door. It provides a convenient gripping surface that mediates the interaction between the user's hand and the door's recessed grip, improving ease of operation without requiring structural changes to the door itself.
2Reliability
If the door panel is made with mesh screen to prevent insect ingress, then protection against insects is improved, but the durability deteriorates due to fragility and risk of tearing
Solution Approach 1:
The handle ridge serves as an intermediary that redirects handling forces away from the fragile mesh screen. By providing a dedicated gripping surface on the door frame, it prevents users from directly grasping and potentially damaging the mesh screen, thereby improving durability without compromising insect protection.
3Strength
If a thick lateral support member is used for the handle attachment, then the strength and rigidity are improved, but the adaptability to narrow door clearances deteriorates
Solution Approach 1:
The lateral support member is designed with optimized dimensional parameters - sufficiently thick to provide structural strength and rigidity for handling forces, yet thin enough to accommodate narrow door clearances and proximity to other door components. This parameter optimization resolves the contradiction between strength and adaptability.
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
The door handle attachment enhances the ease of use for sliding doors by allowing users to apply force conveniently, reducing wear and tear, and accommodating users of all abilities and heights, while maintaining aesthetic appeal and compatibility with various door designs.
Implementation Method 1
The back side of the lateral support member comprises an adhesive adapted for mounting the door handle attachment on the door of interest

AI summary
A door handle attachment is provided having (1) at least one lateral support member, (2) a handle ridge, and (3) an adhesive backside. The lateral support members are coupled along one longitudinal edge at a substantially right angle to the handle ridge, such that the handle ridge rises up away from the lateral support members. The adhesive backside is formed from the posterior surface, i.e. the underside of the lateral support members, and is substantially coated with an adhesive.
