Sockliner Assemblies With Adjustable Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sockliners often fail to provide adequate support and comfort, especially for the arch area of the foot, leading to skin irritation and heat generation due to varying contact between the foot and the sockliner during movement.
Innovation Solution
A sockliner assembly comprising a sockliner with adjustable cables or straps that form a hammock-like structure, ensuring consistent contact with the foot by tension adjustment, reducing friction and irritation through customizable fit and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional sockliners are used, then the structure is simple, but the contact consistency with the foot deteriorates during movement
Solution Approach 1:
The sockliner is transformed from a static component to a dynamic one by incorporating adjustable cables and straps that can be tensioned to adapt to foot movement. The cables connect the sockliner to the footwear upper, allowing the sockliner to maintain contact with the foot throughout the gait cycle while moving with the foot's natural motion.
Solution Approach 2:
The sockliner system is divided into multiple functional components: the sockliner itself, adjustable cables, straps, and tensioning mechanisms. This segmentation allows each component to perform its specific function - the sockliner provides comfort, the cables provide structural support, and the tensioning mechanisms allow for customization - while working together to maintain consistent contact.
2Adaptability or versatility
If adjustable cables and straps are added to form a hammock-like structure, then the support and comfort are improved, but the device complexity increases
Solution Approach 1:
The cable and strap system serves multiple functions simultaneously: it provides structural support to maintain sockliner position, enables customization of fit through adjustment mechanisms, and creates the hammock-like structure for enhanced comfort. This multi-functionality justifies the added complexity by delivering multiple benefits from a single integrated system.
Solution Approach 2:
The system allows for parameter changes in tension and positioning through adjustable cables and straps. Users can modify the tension levels to achieve the desired fit and support, transforming the sockliner from a fixed component to an adaptable system that can be customized to individual foot shapes and preferences.
3Object-affected harmful factors
If the sockliner is tensioned to maintain contact with the foot, then skin irritation and heat generation are reduced, but the ease of adjustment decreases
Solution Approach 1:
The tensioning system is designed to be self-adjusting through the interaction of cables, straps, and the natural movement of the foot. As the foot moves during gait, the cables automatically tension and release, maintaining consistent contact without requiring active user intervention. This self-service mechanism reduces skin irritation while minimizing the adjustment burden on the user.

AI summary
A sockliner assembly can comprise a sockliner and one or more cables. The sockliner can have an upper surface, a lower surface, and a side surface extending between the upper and lower surfaces and defining a peripheral edge of the sockliner. The first cable can have a first attached cable segment and a first free cable segment. The first attached cable segment can be coupled to the sockliner. The first free cable segment can extend from the first attached cable segment and can extend beyond the peripheral edge of the sockliner.
