Dual Layer Slipper Sock With Nested Inner Pouch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art slipper socks often require additional components like insoles and fasteners that can be uncomfortable and fail to adequately insulate the foot, especially in cold environments, while also being difficult to manufacture using conventional sock machinery.
Innovation Solution
A dual-layer slipper sock design featuring an outer pouch made of knitted material and an inner pouch with a high pile texture, where the inner pouch is inserted into the outer pouch to form a collar and provide insulation, with optional grippers on the sole for traction, all manufactured using conventional sock machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an outsole is fastened to the underside of the sock portion using fasteners, then the slipper sock provides protection from the ground, but the fasteners may penetrate or be felt through the sock body causing discomfort
Solution Approach 1:
The patent uses a dual-layer construction where an inner sock layer is nested within an outer slipper layer. The fasteners attach the outsole to the outer slipper layer, not the inner sock layer, so the fasteners are isolated from direct contact with the foot. This nesting arrangement allows the fasteners to provide ground protection while preventing discomfort to the wearer.
2Ease of manufacture
If the slipper sock uses a single layer construction, then it is simpler to manufacture, but it fails to provide adequate insulation from cold surfaces
Solution Approach 1:
The slipper sock is divided into two functional layers: an inner sock layer made of soft, insulating material for warmth and comfort, and an outer slipper layer with an attached outsole for ground protection and traction. This segmentation allows each layer to be optimized for its specific function while maintaining ease of manufacture using conventional sock-making machinery for both layers.
3Adaptability or versatility
If the slipper sock accommodates a wide range of foot sizes, then it increases versatility, but it may compromise the fit and comfort
Solution Approach 1:
The slipper sock incorporates elastic materials in both the inner sock layer and outer slipper layer, allowing the structure to dynamically adapt to different foot sizes. The elastic properties enable the layers to stretch and conform to the wearer's foot while maintaining a secure fit, thus achieving versatility across size ranges without compromising comfort.

AI summary
A slipper sock is formed from an outer pouch and an inner pouch shaped to receive and encapsulate a person's foot. A border around an opening in the inner pouch is placed over a border around an opening in the outer pouch. The inner pouch and outer pouch are affixed together at the interface of the overlapping borders surrounding the openings of the pouches. The inner pouch which can be made of pile material is then inserted through the opening of and into the outer pouch and spread to conform to the shape of the outer pouch. The border of the inner pouch can form a collar surrounding the opening of the outer pouch.
