Removable Insulated Container Handle for Thermal Grip Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drinkware containers with handles lack efficient thermal management, as the handles do not effectively regulate temperature changes, potentially causing discomfort during use of hot or cold beverages.
Innovation Solution
The design of a handle with a ring portion and a handle portion made from materials with different thermal conductivities, where the handle is removably engaged with the container, featuring an engagement layer and a base portion with an annular wall, allowing for better grip and temperature regulation by using materials with a lower thermal conductivity than the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the handle is made from the same material as the container, then the manufacturing process is simplified, but the thermal management performance deteriorates
Solution Approach 1:
The handle is constructed from multiple materials with different thermal conductivities: a core structure made from container-matching material for ease of manufacturing, and an outer layer made from low thermal conductivity material (0.02-0.05 W/mK) for thermal insulation. This composite structure resolves the contradiction by combining manufacturing simplicity with superior thermal management.
Solution Approach 2:
Different portions of the handle are assigned different material properties based on their functional requirements. The inner core uses material matching the container for structural integrity and manufacturing ease, while the outer surface uses thermally insulating material for user comfort. This local differentiation resolves the thermal management issue without compromising manufacturing efficiency.
2Use of energy by moving object
If the handle is made from material with high thermal conductivity, then heat transfer efficiency is improved, but user comfort deteriorates due to temperature extremes
Solution Approach 1:
The handle employs a composite material structure where the inner core provides thermal conductivity for heat transfer efficiency, while the outer insulating layer (0.02-0.05 W/mK) prevents excessive heat transfer to the user's hand. This resolves the contradiction by allowing efficient thermal regulation while maintaining user comfort through the insulating barrier.
3Reliability
If the engagement layer is added to the ring portion, then the grip security is improved, but the device complexity increases
Solution Approach 1:
The engagement layer is integrated into the molding process of the handle, combining the structural formation and engagement layer application in a single manufacturing step. This merges two functions (structural integrity and grip security) into one process, improving grip reliability without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The handle effectively maintains a comfortable temperature, staying cooler during hot days and warmer during cold days, enhancing user experience by providing a secure grip and improved thermal insulation.
Implementation Method 1
The inside surface of the ring portion may contain an engagement layer... The inside surface of the base portion may contain an engagement layer
Implementation Method 2
made from materials with a lower thermal conductivity than the container... the first material may have a thermal conductivity of about 0.1 W/(m*K) to about 0.22 W/(m*K)

AI summary
Containers can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The second outer wall can include a second end configured to support the container on a surface. The containers can include a removably engaged handle.
