Bottle Anti-Scald Handle with Interlayer Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottles with integrated handles suffer from heat conduction from the water-holding cavity, making them inconvenient to hold when filled with hot water and difficult to clean due to trapped impurities.
Innovation Solution
A bottle design featuring a handheld portion with an interlayer structure that is independent of the bottle body, allowing for thermal insulation and easy assembly/disassembly, with a sunken space area on the bottle body to house the handle, preventing direct communication between the handle and bottle cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the handle inner cavity communicates with the bottle water-holding cavity, then the handle can be integrated with the bottle body, but the handle becomes heated when filled with hot water making it inconvenient to hold
Solution Approach 1:
The handle is divided into two independent parts: the bottle body cavity and the handle cavity. The handle cavity does not communicate with the bottle cavity, creating separate thermal zones. This segmentation prevents heat from the hot water in the bottle from transferring to the handle, solving the scalding problem while maintaining an integrated appearance.
Solution Approach 2:
The patent introduces an intermediary barrier (the non-communicating cavity structure) between the hot water in the bottle and the handle. This intermediary prevents direct thermal contact, allowing the handle to remain cool even when the bottle contains hot water, thus resolving the temperature contradiction.
2Device complexity
If the handle inner cavity communicates with the bottle water-holding cavity, then the handle can be integrated with the bottle body, but impurities left in the handle inner cavity cause cleaning inconvenience
Solution Approach 1:
By segmenting the handle cavity from the bottle water-holding cavity, the patent creates a separate, isolated space in the handle. This segmentation allows the handle cavity to be cleaned independently using a separate water stream, preventing impurity accumulation and making cleaning convenient while maintaining the integrated handle structure.
Solution Approach 2:
The patent extracts the handle cavity from the communication system with the bottle cavity, creating an independent cleaning zone. This extraction allows cleaning fluid to be directed specifically at the handle cavity without being mixed with bottle contents, solving the cleaning convenience problem while preserving the integrated design.
3Temperature
If the handheld portion is made as an interlayer structure with internal cavity, then thermal insulation is provided, but the structure becomes more complex
Solution Approach 1:
The handle is segmented into multiple layers with an internal cavity, creating a thermal insulation barrier. This segmentation into layered structure with air gaps or insulating material provides effective thermal protection while the modular nature of the segmentation keeps the manufacturing process manageable.
Solution Approach 2:
The patent employs a nested structure where the handle cavity is positioned within the overall handle assembly. This nesting arrangement provides thermal insulation through the layered configuration while efficiently utilizing space, achieving good insulation performance without excessive structural complexity.

AI summary
A bottle with an anti-scald handle is provided, including a bottle body internally provided with a cavity and a handheld portion independent of the bottle body, and the handheld portion is an interlayer structure internally provided with a cavity; an inward sunken space area is provided on the bottle body; a height of the handheld portion matches the space area, and when being placed in the space area, the handheld portion is fixed with the bottle body to form a handle of the bottle. On the premise of not changing the overall shape of the bottle, the handle portion is redesigned to make the handle have an anti-scald function and solve the problem of inconvenience to clean.
