Handle Transposition Adapter for Sliding Door Corner Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sliding door frames with corner structures face difficulties in accessing and handling the leaf handle, especially when the frame shuts, as the handle is close to the vertical side of the corner, leading to cumbersome operation and limited practicality.
Innovation Solution
An adapter mechanism for handle installation transposition is introduced, which includes a case with grooves allowing movement, featuring components to transmit motion from the handle to the lock, ensuring the handle remains at a distance from the locking mechanism, facilitating easy access and operation by allowing motion transmission from the external to the internal profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the handle is placed close to the locking mechanism on the vertical side of the corner, then the locking mechanism can be compact and simple, but the access and handling of the handle become difficult
Solution Approach 1:
The patent introduces an adapter as an intermediary component that connects the handle to the locking mechanism. The adapter includes a first element that receives handle motion and a second element that transmits motion to the lock, allowing the handle to be positioned away from the locking mechanism while maintaining functional connection. This mediator resolves the contradiction by enabling both compact locking mechanism design and improved handle accessibility.
Solution Approach 2:
The patent divides the motion transmission function into separate components: the handle, the adapter (with first and second elements), and the locking mechanism. This segmentation allows each component to be optimized independently - the locking mechanism remains compact while the adapter extends the handle position to improve accessibility, resolving the spatial conflict between compactness and accessibility.
2Ease of operation
If the handle is positioned at a distance from the locking mechanism, then handle accessibility is improved, but the motion transmission mechanism becomes more complex
Solution Approach 1:
The adapter serves as a simple intermediary that directly transmits motion from the handle to the locking mechanism without requiring complex transmission systems. The first element receives motion from the handle and the second element transmits it to the lock, creating a straightforward motion path that minimizes mechanical complexity while achieving the desired handle positioning.
Solution Approach 2:
The adapter is designed to be self-contained, with the first and second elements working together to automatically transmit motion without requiring additional intermediate components or complex control mechanisms. The adapter handles the motion transmission function independently, reducing overall system complexity while enabling improved handle accessibility.
3Volume of moving object
If corner openings are covered by sliding frames with handles close together, then the structure can be compact, but the handles may bump into each other during operation
Solution Approach 1:
The adapter acts as a spatial intermediary that relocates the handle position away from the locking mechanism. In corner structures with multiple sliding frames, this allows handles to be positioned farther apart, preventing collisions during operation while maintaining the compact overall structure. The adapter mediates between the compact structural requirement and the need for reliable, collision-free handle operation.

AI summary
Adaptor for handle installation transposition consisting of a case (20) with two caps (1 and 2), a component transmitting the motion of the handle (5) and a component transmitting the motion (4) to the lock. The two caps feature opposite semi-circular grooves (6 and 7) for the movement of the component transmitting the motion (4) to the lock and the component transmitting the motion of the handle (5).
