Door Handle with Internal Movable Piece for Profile Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window handles face limitations in adaptability to various European-type profiles and suffer from user contact with the handle base during operation, aesthetic issues, and material inefficiencies due to complex mechanisms and high production costs.
Innovation Solution
A handle design with a base integrated inside the profile, featuring a movable piece and elastic means to adapt to different profile widths and compensate for wear, ensuring secure attachment and minimalistic aesthetics by eliminating external base contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle base is arranged outside the profile, then the handle mechanism can be mounted on existing profiles, but the user comes into contact with the base during operation making it uncomfortable and aesthetically inappropriate
Solution Approach 1:
The transmission mechanism is nested inside the profile channel, with the movable piece positioned between the profile wing and the transmission mechanism. This nesting arrangement eliminates the external base that causes user contact discomfort while maintaining all necessary mechanical functions within the profile structure.
2Ease of operation
If the handle base is integrated inside the profile, then user comfort and aesthetics are improved, but the handle cannot adapt to variations in profile dimensions and wear
Solution Approach 1:
The movable piece is designed to move in the direction defined by the actuating spindle, enabling dynamic adjustment to compensate for variations in profile thickness, gaps, and wear. This dynamic capability allows the integrated handle to adapt to different profile dimensions while maintaining proper lever positioning and operation.
Solution Approach 2:
The movable piece changes its position parameter along the actuating spindle direction to accommodate variations in profile dimensions. By allowing positional adjustment within the integrated structure, the handle maintains adaptability to profile variations and wear without requiring an external base.
3Adaptability or versatility
If a movable piece is added to adapt to profile variations, then adaptability is improved, but the mechanism complexity and material costs increase
Solution Approach 1:
The handle is segmented into distinct functional components: the lever, the transmission mechanism inside the profile, and the movable piece positioned between them. This segmentation allows each component to perform its specific function independently, achieving adaptability through a relatively simple movable piece rather than a complex overall mechanism.
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 handle effectively adapts to all European-type profiles and compensates for wear, enhancing user safety and aesthetic appeal while reducing material costs and production complexity.

AI summary
It comprises: a lever (101); a transmission mechanism (108) inside a profile (130) of the door or window leaf; a movable piece (106) arranged between a wing (140) of the profile (130) of the leaf that defines the outer portion of the leaf and the transmission mechanism (108) to adapt the handle to different widths of the profile (130); the attachment means (153, 154) for attaching the lever (101) to the movable piece (106) that contribute, along with elastic means (155) that change the relative position of the handle (101) with respect to the movable piece (106) to correct the gaps or wear that is produced in the direction defined by the actuating spindle of the lever (101). It enables the handle to be adapted to all European-type profiles and to the aforementioned existing gaps or wear, and prevents the base of the handle from protruding from the profile.
