Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Novice operators face difficulties in attaching cantilevers to cantilever holders due to the need for precise positioning and angle control, often resulting in cantilever drops or misalignment.
Innovation Solution
A cantilever attachment fitting that includes a sliding platform, a base for fixing the cantilever holder, a pressing unit for stabilizing the holder, and a lifting mechanism to create a gap between the attachment platform and the pressing member, allowing the operator to focus solely on positioning the cantilever without worrying about angle or location shifts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually positions the cantilever on the attachment platform while pressing the holder, then the cantilever can be attached, but the operator must simultaneously control positioning and angle, increasing operation difficulty
Solution Approach 1:
The device separates the positioning function from the angle control function. The sliding platform handles positioning along the X-axis, while the pressing member independently controls the attachment angle. This segmentation allows the operator to focus on one dimension at a time, reducing operational complexity.
Solution Approach 2:
The sliding platform acts as an intermediary mechanism between the operator and the cantilever attachment process. It provides a controlled path for positioning the cantilever, mediating the interaction between the operator's manual input and the final attachment position, thereby simplifying the overall operation.
2Manufacturing precision
If the operator focuses on precise positioning of the cantilever, then attachment accuracy improves, but the operator cannot simultaneously control the angle, leading to potential misalignment
Solution Approach 1:
The attachment mechanism is divided into independent functional components: the sliding platform for positional alignment and the pressing member for angular control. This segmentation enables precise positioning through the sliding platform while the pressing member separately manages the attachment angle, ensuring both precision and ease of operation.
Solution Approach 2:
The pressing member is designed to be movable, allowing dynamic adjustment of the attachment angle during the attachment process. This dynamic capability enables the operator to first position the cantilever precisely using the sliding platform, then adjust the angle using the pressing member without compromising either positioning accuracy or operational simplicity.
3Ease of operation
If the attachment platform and pressing member are in direct contact, then the structure is compact, but the operator cannot access the cantilever for positioning
Solution Approach 1:
The pressing member is designed to move vertically to create a gap between the attachment platform and the pressing surface. This dynamic gap creation allows the operator to insert and position the cantilever when needed, while maintaining a compact structure when the pressing member is in its lower position. The gap appears only during operation, eliminating the need for permanent clearance.
Solution Approach 2:
The sliding platform is positioned within the structure formed by the attachment platform and pressing member. When the pressing member is lowered, it creates a nested configuration that accommodates the sliding platform and provides access space for the cantilever, maximizing space utilization while maintaining accessibility.
4Reliability
If the operator uses both hands to control positioning and pressing, then attachment can be achieved, but novice operators struggle with coordinating both actions
Solution Approach 1:
The device segments the attachment task into distinct functional zones: the sliding platform for positioning (typically controlled by one hand) and the pressing member for securing (controlled by the other hand). This segmentation provides intuitive hand allocation that reduces coordination complexity for novice operators while maintaining reliable attachment.
Solution Approach 2:
The sliding platform automatically guides the cantilever into the correct positional alignment as it moves, reducing the need for manual positioning adjustments. This self-aligning feature allows novice operators to focus on the essential actions of moving the platform and activating the pressing member, improving reliability without requiring complex coordination skills.

AI summary
The invention provides a cantilever attachment fitting that makes it easy to attach a cantilever to a cantilever holder. The cantilever attachment fitting has an attachment platform of which the upper surface is to have a cantilever placed on, a pressing member for pressing the cantilever against the upper surface of the attachment platform, and a lifting mechanism for moving the pressing member upward from the upper surface of the attachment platform. The cantilever attachment fitting is further provided with: a sliding platform having a sliding surface for sliding the cantilever toward the attachment platform; a base for fixing the cantilever holder in the horizontal direction so that the attachment platform is in a predetermined location relative to the sliding platform; and a pressing unit for pressing downward the cantilever holder fixed to the base.
