Solution Overview
Problem
Existing heat insulating containers face challenges in maintaining a reliable heat insulating effect and ease of manufacturing due to complex mechanisms and high production costs, as well as difficulties in forming a heat insulating grip portion without deformation when gripped.
Innovation Solution
A heat insulating container design featuring a sleeve with slits forming strips that bend and project to create a grip portion, with specific broken line configurations and angles that lock protrusions together, allowing for simple operation and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the strips are made to project and form a heat insulating grip portion by sliding the sleeve, then the heat insulating effect is improved, but the strips may return to the original shape when gripped strongly, reducing the heat insulating effect
Solution Approach 1:
The sleeve is divided into multiple strips by creating slits that extend partially through the sleeve wall. These segmented strips can project outward to form a heat insulating grip portion while maintaining individual structural integrity through the slit configuration, preventing them from returning to the original shape when gripped.
Solution Approach 2:
The slits are pre-formed in the sleeve at specific locations and orientations before use. This preliminary configuration ensures that when the sleeve is slid or deformed, the strips automatically project outward in a controlled manner to form the heat insulating grip portion, and the pre-positioned slit geometry prevents reversal when gripped.
2Reliability
If the strips are made long and irreversibly folded during sliding, then the heat insulating grip portion is formed, but the operation complexity and production time increase
Solution Approach 1:
The slits are pre-formed in the sleeve at specific locations and orientations before use. This preliminary configuration ensures that when the sleeve is slid or deformed, the strips automatically project outward in a controlled manner to form the heat insulating grip portion, eliminating the need for complex folding operations during assembly.
Solution Approach 2:
The sleeve structure itself, through the pre-configured slits, automatically forms the heat insulating grip portion when slid. The strips self-project and self-lock in position without requiring external tools, complex folding operations, or additional assembly steps, thereby simplifying the manufacturing process and reducing time consumption.
3Reliability
If a complex fold pattern or separate fixing member is used to maintain protrusions, then the heat insulating effect is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The sleeve is divided into multiple strips by creating slits that extend partially through the sleeve wall. These segmented strips can project outward to form a heat insulating grip portion while maintaining individual structural integrity through the slit configuration, eliminating the need for separate fixing members or complex fold patterns.
Solution Approach 2:
The slit configuration serves multiple functions simultaneously: it creates the heat insulating grip portion, maintains the protrusion shape, and provides structural support without requiring additional components. This multi-functional design eliminates the need for separate fixing members or complex fold patterns, reducing overall device complexity.

AI summary
Provided is a heat insulation container which can be easily produced and assembled at a reduced cost, in which a heat insulation grip portion can be formed by a simple operation, in which a strip-shaped projection is maintained and a heat insulation effect can be reliably maintained even when the container is externally gripped, and which can be reliably gripped without being deformed. The heat insulation container (100) can be formed with the heat insulation grip portion by sliding a sleeve (120) on which a plurality of strips (121, 122) are formed by a plurality of slits (130), wherein at least one of the slits (130) comprises a bent portion (131) which defines a protrusion (127) and a depression (128) in each of the adjacent strips (121, 122).
