Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cups with detachable handles require tools for removal and storage, leading to inconvenience and potential loss of parts, and exposed bolt structures can rust, affecting aesthetics.
Innovation Solution
A cup design featuring a fixing block on the cup body and a rotary switch on the handle that allows for tool-free detachment and attachment by rotating the switch, eliminating loose parts and preventing rust through a secure, aesthetically pleasing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bolt structure is used to detachably connect the handle to the cup body, then the handle can be selectively attached or removed, but tools are required for removal and storage, causing inconvenience and potential loss of parts
Solution Approach 1:
The patent extracts the bolt structure from the visible exterior and relocates it to the interior of the cup body. The fixing block with bolt is hidden inside the cup body, while the handle features a fixing connector that interfaces with it. This allows the handle to be detachably connected without exposing the bolt structure externally, eliminating the need for tools and preventing loss of parts.
Solution Approach 2:
The fixing block containing the bolt structure is nested within the cup body interior. The handle's fixing connector engages with this nested fixing block from the exterior, creating a layered structure where the fastening mechanism is contained within the cup body while still enabling handle attachment and detachment.
2Adaptability or versatility
If a bolt structure is exposed on the cup surface, then the handle can be attached, but long term use causes rust on the bolt surface, affecting aesthetics
Solution Approach 1:
The bolt structure is extracted from the external surface and relocated to the interior of the cup body. By hiding the fixing block with bolt inside the cup body and using a fixing connector on the handle that engages with it, the bolt structure is no longer exposed to air and moisture, preventing rust while maintaining the detachable handle functionality.
3Adaptability or versatility
If a bolt structure is used for handle attachment, then the handle can be securely fixed, but the exposed bolt structure requires storage after removal, causing inconvenience
Solution Approach 1:
The bolt structure is extracted from the handle assembly and relocated to the cup body interior as part of the fixing block. When the handle is removed, the bolt remains stored within the cup body rather than being a separate loose part requiring external storage. This eliminates the time and inconvenience associated with bolt storage while maintaining secure handle attachment.

AI summary
This application discloses a cup. The cup includes a cup body and a handle, a fixing block is fixedly connected to an outer peripheral wall of the cup body, and a top end of the handle is provided with a fixing connector configured to be detachably connected to the fixing block. Specifically, the fixing connector includes an accommodating slot configured to accommodate the fixing block and a rotary switch passing through the accommodating slot, and an end, facing the accommodating slot, of the fixing block is provided with a position-limiting retaining groove. When a portion, located in the accommodating slot is engaged in the position-limiting retaining groove, the handle is fixed to the cup body, and when the portion located in the accommodating slot is rotated to be able to disengage from the position-limiting retaining groove, the handle is removed from the cup body.
