Operating bottle with automatic orienting handle assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottles with handles for babies or children often require manual readjustment due to changes in handle orientation when reattached, especially when the bottle has an asymmetric top structure with a spout or straw offset from the axial center, making it difficult for young users to handle properly.
Innovation Solution
A self-orienting handle assembly that locks onto a counterpart locking structure on the lid as it is screwed onto the container, ensuring the handle is always oriented correctly relative to the spout or straw, preventing rotation and maintaining proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If handles are attached to a ring that is inserted into the outer periphery of the bottle body, then handles can be removed for cleaning purposes, but the orientation of the handles may change or shift when reattached
Solution Approach 1:
The locking structure employs asymmetric geometry where the protrusion on the ring has a specific shape that corresponds to a matching notch on the lid. This asymmetric design ensures that the ring can only be positioned in one specific orientation relative to the lid, preventing any rotation or shifting of the handles while still allowing for easy attachment and removal for cleaning purposes.
2Adaptability or versatility
If the bottle has an asymmetric top structure with a spout or straw offset from the axial center, then the bottle can be designed for functional purposes, but manual readjustment is required when handles are reattached
Solution Approach 1:
The locking structure employs asymmetric geometry where the protrusion on the ring has a specific shape that corresponds to a matching notch on the lid. This asymmetric design ensures that the ring can only be positioned in one specific orientation relative to the lid, preventing any rotation or shifting of the handles while still allowing for easy attachment and removal for cleaning purposes.
3Reliability
If a locking structure with protrusion and notch is used to secure the lid to the container, then the lid is firmly attached, but the structure becomes more complex
Solution Approach 1:
The locking structure is integrated directly into the existing components of the bottle system. The protrusion is formed as part of the ring structure, and the notch is formed as part of the lid, eliminating the need for separate locking mechanisms or additional parts. This merging approach provides secure attachment while maintaining simplicity in the overall design.

AI summary
Embodiments relate to a self-orienting handle assembly that is oriented in a predetermined direction relative to a lid when the lid is screwed onto a container. The handle assembly includes a locking structure that locks onto a counterpart locking structure of the lid as the lid is screwed onto the container. The locking structure may include at least one of a protrusion or a notch, and the counterpart locking structure may have an inverse shape. When the lid is screwed onto the container, the locking structure engages the counterpart locking structure and cause the handle assembly to rotate with the lid. When the lid is screwed onto the container, the locking structure locks onto the counterpart locking structure, and thereby prevents the handle assembly from rotating relative to the lid.
