Adjustable Frame Support Positioning for Jigless Hole-Making
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of aircraft components, such as fuselages and wings, requires numerous types of jigs for positioning and machining due to their varying shapes, leading to increased time and cost in preparing and maintaining these jigs.
Innovation Solution
A component production system that uses support parts to detect and adjust to the shape of long members, allowing for precise machining without the need for multiple jigs by prerecording shape data and using a detection unit to guide the support parts to match the member's shape, enabling machining operations like hole-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If many types of jigs are prepared for positioning and machining different shaped components, then machining precision for various components is improved, but device complexity and preparation time increase
Solution Approach 1:
The patent applies universality by designing a single positioning jig that can accommodate multiple types of long members with different shapes (circular, elliptical, rectangular cross-sections). The jig achieves this through movable support parts that can be adjusted to match various member geometries, eliminating the need for separate dedicated jigs for each component type while maintaining machining precision.
Solution Approach 2:
The patent implements dynamics by using movable support parts that can be positioned and adjusted along the positioning jig. These support parts can move to different locations and adapt to different member shapes, allowing the same jig to dynamically reconfigure for various machining tasks rather than requiring static, dedicated fixtures for each component type.
2Manufacturing precision
If many types of jigs are prepared for different component shapes, then positioning accuracy for various members is improved, but loss of time for jig preparation and maintenance increases
Solution Approach 1:
The positioning jig serves multiple functions by accommodating different member shapes and sizes through its adjustable support parts. This multi-functionality eliminates the time required to prepare, switch between, and maintain multiple dedicated jigs, while still achieving accurate positioning for various component types through the movable support mechanism.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the positioning jig with movable support parts that can be quickly adjusted to the required positions before machining begins. This allows the system to prepare for different member types in advance rather than requiring complete jig changes, reducing setup time while maintaining positioning accuracy.
3Ease of operation
If fixed support positions are used for long members, then ease of operation is improved, but manufacturing precision decreases due to member deformation
Solution Approach 1:
The patent resolves this contradiction by making the support parts movable rather than fixed. The support parts can be positioned at optimal locations along the member length and adjusted to match the member's cross-sectional shape, providing both ease of operation through simple placement and manufacturing precision by preventing deformation through proper support configuration.
Solution Approach 2:
The patent applies local quality by providing support at multiple discrete locations along the member rather than uniform fixed support. The movable support parts can be positioned at specific critical points where support is most needed to prevent deformation, while maintaining ease of operation through their adjustable nature.

AI summary
A component production method includes: a step of binding a long frame by a plurality of support devices arranged along the frame; a step of measuring, with a distance sensor, a distance to the frame supported by the plurality of support devices; a step in which, based on frame shape data prerecorded in a memory, the support devices move support positions where the frame is supported so that a calculated radial position of the frame being supported by the support devices matches the data about the frame shape; a step of fixing the frame in a state in which the data about the frame shape matches the radial position of the frame; and a step of performing a hole-making operation on the fixed frame.
