Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable frame-knitting devices are limited in their ability to accommodate varying sizes and shapes of knitted materials, as they lack a modular and easily adjustable structure.
Innovation Solution
A modular hand loom comprising interconnected elongate sections with snap-fit connectors and an adjustable hand loom with elastic coupling and sliding pegs, allowing for easy assembly and disassembly, and adjustable width between rails to accommodate different sizes and shapes of knitted items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a typical loom with fixed frame is used, then structural stability is maintained, but adaptability to different sizes and shapes of knitted materials is limited
Solution Approach 1:
The loom frame is divided into multiple detachable sections that can be connected and disconnected. Each section has standardized connectors (tabs and slots) allowing the frame to be reconfigured into different sizes and shapes by assembling different combinations of sections, thus providing adaptability without requiring a completely different frame for each configuration.
Solution Approach 2:
The frame structure transitions from a fixed, static configuration to a dynamic, reconfigurable system. The connectors allow the frame to be easily assembled, disassembled, and reconfigured during use, enabling the loom to adapt to different knitting projects while maintaining structural integrity through the locking mechanism.
2Adaptability or versatility
If an adjustable frame-knitting device is used, then adaptability to different sizes is improved, but ease of operation deteriorates due to complex adjustment mechanisms
Solution Approach 1:
The frame is segmented into modular sections with standardized connectors. This segmentation allows the frame to be easily assembled and disassembled by simply connecting and disconnecting the sections, eliminating complex adjustment mechanisms while maintaining adaptability to different sizes.
Solution Approach 2:
The connector design incorporates a self-locking mechanism where the tab automatically engages with the slot and locks into place through a simple pushing motion. The release member allows for easy disconnection by actuating the locking mechanism, making the entire assembly and disassembly process simple and intuitive without requiring complex tools or procedures.
3Ease of operation
If a modular connector system is used, then ease of assembly is improved, but reliability of connection may deteriorate
Solution Approach 1:
The connector design incorporates guide surfaces and alignment features that automatically guide the tab into the correct position within the slot during assembly. This preliminary alignment action ensures proper engagement before the locking mechanism activates, maintaining connection reliability while keeping the assembly process simple.
Solution Approach 2:
The locking member automatically engages with the retaining surface when the tab is inserted into the slot, creating a self-locking connection that ensures reliable attachment without requiring additional fastening steps. The release member provides a simple mechanism to activate the unlocking action, maintaining both ease of operation and connection stability.
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
Enables the creation of various sized and shaped articles by allowing for easy adjustment of loom sections and width, enhancing versatility and flexibility in knitting.
Implementation Method 1
an elastic member coupling the first rail and the second rail such that the first rail and the second rail are movable relative to one another to increase the width therebetween against a restoring force of the elastic member
Implementation Method 2
the tab connector is configured to engage the slot connector in a snap fit arrangement such that a locking member of one of the tab connector and the slot connector is movable between a first position in which the locking member is in locking engagement with a retaining surface of the other of the tab connector and the slot connector

AI summary
A plurality of elongate loom sections are interconnected via male and female connectors to form a modular hand loom having a size that is adjustable. A first loom section has a male connector extending from an end portion of the first loom section. A second loom section has a female connector configured to connect to the male connector in a snap fit arrangement. The second loom section includes a release member to facilitate disconnection of the male connector from the female connector.
