Sleeve Cuff Pocket Structure for Warmth Without Movement Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Garments with sleeves often have cuffs that restrict hand movement and comfort when pockets are used for hand storage, and there is a need for improved warmth and functionality in cold environments.
Innovation Solution
Incorporating cuff pockets within the sleeve cuffs that are designed with a lower floor to maintain comfort and depth without increasing sleeve length, optionally with heating elements for added warmth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If pockets are added to sleeve cuffs for hand storage, then hand warmth and comfort are improved, but hand movement restriction and discomfort increase
Solution Approach 1:
The cuff is divided into multiple sections: a main body portion and an extended portion that projects below the sleeve opening. The pocket is integrated into this extended portion, creating a segmented structure that allows the hand to be stored in the pocket while maintaining some cuff coverage and movement capability.
Solution Approach 2:
The cuff extends in a downward direction below the sleeve opening, creating a third dimension (depth/extension) rather than simply adding width or length along the arm. This vertical extension allows the pocket to be positioned lower, providing deeper hand storage without increasing the horizontal circumference of the cuff.
2Ease of operation
If cuff pockets are made deeper for better hand retention, then hand storage comfort is improved, but sleeve length must be increased
Solution Approach 1:
Instead of increasing the horizontal length of the sleeve, the pocket depth is achieved by extending the cuff in a vertical dimension below the sleeve opening. This allows the pocket to reach deeper into the arm while the sleeve itself maintains its original length.
Solution Approach 2:
The pocket is nested within the extended cuff portion, utilizing the space created by the cuff's projection below the sleeve opening. This nested configuration allows the pocket to be deeper without requiring the sleeve to be longer, as the pocket occupies the space within the cuff extension.
3Temperature
If heating elements are added to cuff pockets for warmth, then thermal insulation is improved, but device complexity and cost increase
Solution Approach 1:
The heating element is integrated directly into the pocket structure, allowing the pocket to heat itself when needed. This self-service approach eliminates the need for separate heating systems or external heat sources, reducing overall device complexity while providing effective thermal insulation for the hand.
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 cuff pockets provide enhanced comfort and warmth by allowing easier hand insertion and retention, while optional heating elements enhance thermal insulation.
Implementation Method 1
The cuff pocket may include a heating element positioned within the cuff pocket or positioned adjacent to the cuff pocket such that heat generated by the heating element passes through a bottom of the cuff pocket to a hand received within the cuff pocket.

AI summary
A garment includes a torso portion having a shoulder region and a sleeve extending from the shoulder region. The sleeve has an interior terminating at a cuff. A panel is secured within the interior proximate the cuff to form a cuff pocket. The cuff pocket may include a floor the either extends adjacent to an edge of the cuff and/or that is downwardly beyond and outside the interior.
