Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for functional units, such as guide rails and tools, lack reliability and convenience in attachment to workpieces, often requiring cumbersome methods like suction cups which are not always effective.
Innovation Solution
A fastening device with a housing containing an electrically operated vacuum unit that creates negative pressure in a suction area, allowing for reliable and convenient attachment to a base, along with a fastening interface for securing the functional unit, enhancing manageability and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction cup is used for attachment, then the device can be attached to surfaces, but the attachment reliability is insufficient and convenience is reduced
Solution Approach 1:
The patent replaces the mechanical suction cup attachment system with an electrically operated vacuum unit that uses controlled vacuum generation to achieve attachment. This electrical system provides more reliable and controllable attachment compared to passive mechanical suction cups, while also improving ease of operation through electrical control mechanisms.
Solution Approach 2:
The patent employs a vacuum unit that generates negative pressure (vacuum) to attach the fastening device to the base surface. This pneumatic approach using controlled vacuum generation provides superior attachment reliability and convenience compared to simple suction cups, as it allows for controlled attachment and detachment through electrical operation.
2Reliability
If an electrically operated vacuum unit is used, then attachment reliability and convenience are improved, but device complexity increases
Solution Approach 1:
The patent integrates the electrically operated vacuum unit within the housing of the fastening device, combining the attachment mechanism with the structural housing. This merging approach reduces overall system complexity by eliminating separate attachment devices while maintaining improved attachment reliability through the electrically controlled vacuum system.
Solution Approach 2:
The housing serves multiple functions: it provides structural support, contains the vacuum unit, and forms part of the attachment system. This multi-functionality reduces the need for additional components, thereby managing device complexity while achieving reliable attachment through the integrated electrically operated vacuum unit.
