Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting face materials, such as those used in pipe repair, face difficulties in accurately and efficiently joining components due to complex assembly processes and reliability issues with fitting claws, leading to unevenness and increased costs.
Innovation Solution
A slide jig with a support portion, pressing portion, and protrusion guide integrated via a joint portion, allowing for precise alignment and reliable fitting of face material fitting claws with face material connecting member fitting claws, facilitating easy connection of belt-like face materials along a pipe's inner circumference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face materials are connected by fitting face material fitting claws to face material connecting member fitting claws, then the connection reliability is improved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent introduces a jig as an intermediary tool that mediates the connection process between face materials and connecting members. The jig includes positioning portions that guide the fitting claws and connecting members into proper alignment, and pressing portions that apply force to secure the connection. This intermediary device simplifies the complex manual assembly process while ensuring reliable connections.
Solution Approach 2:
The jig performs preliminary actions by pre-positioning and pre-aligning the face material fitting claws with the face material connecting member fitting claws before the actual connection occurs. The positioning portions and pressing portions are designed to guide the components into correct alignment in advance, reducing the complexity of the assembly process and ensuring connection reliability.
2Length of stationary object
If numerous inner face members and fitting members are used to repair long pipe lines, then the repair coverage is improved, but the assembly work becomes significantly troublesome
Solution Approach 1:
The jig serves as a reusable intermediary tool that simplifies the assembly of each individual face material and fitting member connection. By standardizing the connection process through the jig's positioning and pressing mechanisms, the patent reduces the trouble of assembling numerous components, even for long repair lengths.
Solution Approach 2:
The patent divides the repair system into modular segments: multiple face materials and fitting members that can be assembled incrementally using the same jig. This segmentation allows the repair work to be broken down into repetitive, standardized units, making the assembly of numerous components more manageable and less troublesome.
3Ease of operation
If synthetic resin made inner face materials are arranged along the circumferential direction, then the installation process is simplified, but the arrangement accuracy deteriorates causing unevenness
Solution Approach 1:
The jig acts as an intermediary device that maintains the simplicity of circumferential arrangement while improving accuracy. The positioning portions of the jig include features that prevent rotation and ensure precise angular positioning of each face material, allowing workers to easily install materials while achieving high arrangement accuracy and avoiding unevenness.

AI summary
Provided is a slide jig for connecting face materials, in which the face materials can be easily connected together while fitting claws are reliably fit together. The slide jig is used in order to connect belt-like face materials 1 that are arranged side by side in a width direction by respectively fitting face material fitting claws 12, which are respectively formed in grooves 11 that are respectively formed at end portions of the face materials 1 in the width direction, to face material connecting member fitting claws 22 which are oppositely formed in protrusions 21 which are formed in a face material connecting member 2 arranged across the end portions of both the face materials 1 in the width direction. A support portion 31 that is inserted into the groove 11 of the face material 1, a protrusion guide portion 32 that is inserted between the protrusions 21 which are formed in the face material connecting member 2, and a pressing portion 33 that presses a surface of the face material connecting member 2 are integrated with a joint portion 34. The support portion 31 is provided so as to be positioned in a front of a jig 3A in a slide direction, and the protrusion guide portion 32 and the pressing portion 33 are provided so as to be positioned in the rear of the jig 3A in the slide direction.
