Length-Adjustable Roller Skate with Movable Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing length-adjustable roller skates limit size variation to only a few positions and rely on boot structures that restrict expansion and retraction.
Innovation Solution
A length-adjustable roller skate design featuring a front and rear foot support structure connected by a movable connector element, with an adjustment actuator to fix relative positions and adjustable securing elements for securing footwear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a boot structure is used to hold the user's foot, then the skate can provide structural support and stability, but the boot structure limits the extent to which the skate can expand and retract
Solution Approach 1:
The skate is divided into separate front and rear foot support structures that can move independently relative to each other. The front foot support structure includes a front sole surface and the rear foot support structure includes a rear sole surface, allowing each section to adjust independently for better adaptability to different foot sizes without being constrained by a single boot structure.
Solution Approach 2:
The connection between the front and rear foot support structures is made dynamic through a movable connector element that allows the structures to move relative to each other in the longitudinal direction. This dynamic connection enables the skate length to be adjusted between extended and retracted positions while maintaining structural integrity through the adjustment actuator.
2Adaptability or versatility
If the skate length is made adjustable between multiple positions, then users with different foot sizes can be accommodated, but the mechanism to achieve this adds complexity to the device
Solution Approach 1:
A movable connector element acts as an intermediary between the front and rear foot support structures, enabling relative movement while maintaining connection. This intermediary component facilitates length adjustment through a simple sliding or telescoping mechanism rather than requiring complex mechanical systems.
Solution Approach 2:
The adjustment actuator is designed to allow the user to independently adjust the relative position of the front and rear foot support structures without requiring external tools or complex control systems. The actuator engages and disengages automatically or through simple user input, enabling self-service length adjustment.
3Length of moving object
If the front foot support structure is moved in the first direction relative to the rear foot support structure, then the distance between sole surfaces increases, but this requires a mechanism that allows controlled movement and positioning
Solution Approach 1:
The adjustment actuator provides feedback control for the relative positioning of the front and rear foot support structures. As the front structure moves in the first direction, the actuator monitors and controls the movement to ensure precise positioning at desired length settings, making the control mechanism intuitive and reliable for the user.

AI summary
A modular, multi-part roller skate is provided. The multi-part roller skate includes a roller skate body, a front wheel assembly, a rear wheel assembly, a support surface for supporting a footwear of a user, and at least one securing element for securing the footwear to the support surface. The multi-part roller skate is configurable as a modular roller skate with a removable pair of rear wheels, an interchangeable modular roller skate and ice skate, and an interchangeable modular roller skate and cross-country ski/snowshoe. In some embodiments, the multi-part roller skate can also be configured as a length-adjustable skate with a length adjustable skate body that includes separate front and rear foot support structures.
