Handle Device with Modified T and Star Openings for Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handle devices for individuals with limited dexterity or physical disabilities fail to securely accommodate and lock objects, leading to potential movement and removal hazards.
Innovation Solution
A handle device with a hollow cylindrical body featuring modified T- and star-shaped openings, along with a slot that secures objects by allowing insertion and locking mechanisms, preventing movement and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hollow cylindrical body is used for the handle device, then the device is easy to manufacture and has simple structure, but the object can move freely inside and can be easily removed
Solution Approach 1:
The handle device is segmented into multiple functional components: a hollow cylindrical body, a slot structure, and opening structures with tabs. The slot divides the internal space to create locking engagement points, while the opening structures with tabs provide additional securing mechanisms. This segmentation allows the object to be firmly held without requiring a completely complex overall structure.
Solution Approach 2:
The slot and opening structures are pre-configured within the handle device body before the object is inserted. The slot is formed within the cavity with specific geometry that creates locking engagement points, and the openings with tabs are prepared in advance. When the object is inserted, these pre-configured structures automatically engage with the object to prevent movement and removal, eliminating the need for additional locking actions during use.
2Reliability
If the opening is designed with tabs (modified T-structure or star structure), then the object is securely locked and prevented from removal, but the manufacturing complexity and structural complexity increase
Solution Approach 1:
The opening structures with tabs are merged directly into the handle device body as integral features rather than separate components. The modified T-structure or star structure openings are formed as part of the hollow cylindrical body, combining the body structure with the locking mechanism. This merging reduces the number of separate parts and simplifies manufacturing while maintaining the secure locking capability provided by the tabs.

AI summary
The present invention provides a handle device. The handle device includes a hollow body having an outer surface and an inner surface forming a cavity. A slot is formed within the cavity and at least one opening is formed at one end of the body for an insertion of a handle portion of an object. In one embodiment of the present invention, the opening is a modified T-structure of a substantially elongated shape including two tabs located in a center portion of the modified T-structure. The two tabs are substantially perpendicular to the elongated shape of the opening. In another embodiment, the opening is a modified star structure including a central aperture and four sides of a substantially elongated shape extending from the central aperture.
