Adjustable Steel Fixing Jig for Multi-Shape Section Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steel material holding devices are limited in their ability to fix various shapes and sizes of steel materials, particularly failing to accommodate H-shape steel of all standards and large sizes, and cannot handle steel materials like I-shape steel and angled steel pipes effectively.
Innovation Solution
A fixing jig system with a nut, screw shaft, and handle that includes a contact portion and extension members, allowing for adjustable clamping and rotation to securely hold steel materials from multiple directions, enabling the use of a single device for various shapes and sizes by attaching extension members as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple specialized fixing jigs are prepared for each shape and size of H-shape steel, then the steel material can be fixed securely, but the equipment cost, labor cost, and time cost increase significantly
Solution Approach 1:
The patent applies universality by designing a single fixing jig that can accommodate multiple types and sizes of steel materials (H-shape steel, I-shape steel, angled steel pipes, etc.) through interchangeable attachments. The attachment can be adjusted and reconfigured to match different steel material dimensions and shapes, eliminating the need for multiple specialized fixing jigs while maintaining secure fixation for each type.
2Device complexity
If a single fixing jig is used for various shapes and sizes of steel materials, then the equipment cost and operational complexity are reduced, but the ability to securely fix all types of steel materials is compromised
Solution Approach 1:
The patent applies segmentation by dividing the fixing system into a main fixing jig body and interchangeable attachments. The attachment is segmented into adjustable components that can be reconfigured to match different steel material types and sizes. This segmentation allows the single fixing jig to adapt to various steel materials while maintaining secure fixation capabilities for each specific type.
3Adaptability or versatility
If attachments are attached to steel materials in advance and fixed with fixing jigs, then various steel material shapes can be accommodated, but the labor time and operational complexity increase
Solution Approach 1:
The patent applies dynamics by designing the attachment as a movable and adjustable component that can be quickly reconfigured on the fixing jig itself, rather than requiring pre-attachment to the steel material. The attachment can be dynamically adjusted to match different steel material dimensions and shapes during the fixing process, reducing preparation time and operational complexity while maintaining versatility across different steel material types.

AI summary
A fixing jig for fixing a steel material includes a nut, a screw shaft screwed to the nut, a handle attached to the screw shaft, and a contact portion relatively rotatably attached to the handle. A plurality of screw holes are formed in an outer peripheral portion of the contact portion. The first extension member includes a long cylindrical portion, an extension side contact portion provided at a tip end portion of the cylindrical portion, and a connecting portion provided at a base end portion of the cylindrical portion and connected to the contact portion. The connecting portion includes a plurality of through holes formed in an outer peripheral portion of the connecting portion, and long engagement holes each extending from each of the plurality of through holes.
