Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable skate frames lack efficient mechanisms for secure attachment and easy detachment, which can lead to instability and difficulty in converting the skate between modes.
Innovation Solution
A skate design featuring an elongated frame with transverse grooves and pins, a locking device with a spring-biased block member and projections, and a threaded fastener, allowing for secure attachment and easy detachment using a dual side release configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable frame mechanism is implemented, then the skate can be converted between skate mode and conventional shoe mode, but the attachment and detachment mechanisms become complex and may lack stability
Solution Approach 1:
The frame is divided into a first set of laterally spaced apart pins and a second set of laterally spaced apart pins, with corresponding grooves in the base. This segmentation allows independent engagement of multiple connection points, providing stable attachment while maintaining a relatively simple overall structure that enables mode conversion.
2Reliability
If multiple pins and grooves are used for attachment, then stability is improved, but the mechanism becomes more complex and harder to operate
Solution Approach 1:
The first and second sets of pins and grooves are positioned to engage simultaneously, distributing the attachment force across multiple points. This merging of multiple connection elements creates a stable attachment system that operates through a single, unified action, improving ease of operation while maintaining high reliability.
3Ease of operation
If the frame structure is simplified for easy detachment, then ease of operation is improved, but the ability to distribute shear forces is reduced
Solution Approach 1:
The attachment mechanism uses pins extending in a first lateral direction and corresponding grooves oriented in a second lateral direction perpendicular to the first. This dimensional arrangement allows the structure to distribute shear forces effectively across multiple axes while maintaining simplicity for easy attachment and detachment operation.
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 design provides enhanced stability by distributing shear forces across the frame and facilitating easy conversion between skate modes, ensuring secure attachment and efficient detachment.
Implementation Method 1
a spring biased block member disposed in the transverse open groove of the front set
Implementation Method 2
a threaded fastener driven through the positioning member into the threaded hole to fasten the positioning member in the transverse open groove

AI summary
A skate includes an inverted groove-shaped base secured to a boot and including front and rear pins; an elongated frame including front and rear sets of a transverse inner groove and a transverse open groove communicating with the transverse inner groove, and a threaded hole on the transverse open groove of the front set wherein either pin is disposed in the transverse inner groove and the elongated frame abuts an underside of the base; and a locking device including a spring biased block member disposed in the transverse open groove of the front set and having two projections at two ends respectively, a screw driven through a positioning member into the threaded hole to fasten the positioning member in the transverse open groove of the front set so that the block member abuts the front pin to block same in an assembled state.
