Flap Bearing Positioning Element for Faster Closure Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lifting devices for flaps and folding flaps require a time-consuming iterative process to adjust the flap bearing position, especially when two devices are involved, as the position must be checked and corrected multiple times to ensure proper closure, which is inefficient and labor-intensive.
Innovation Solution
A flap bearing system with a positioning element that is displaceably supported on the installation support, allowing the bearing part to adjust and mark the optimal position when the flap is closed, enabling quick and easy adjustment when the flap is open, using a guide and detent connection to facilitate precise positioning and limit displacement ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the flap bearing position is adjusted using the existing iterative process, then the closure position can be checked and corrected, but the adjustment time is significantly increased, especially when multiple lifting devices are involved
Solution Approach 1:
The patent applies preliminary action by providing adjustment aids (markings, guides, or indicators) that are pre-established on the flap bearing or surrounding structure. These aids indicate the correct adjustment position in advance, allowing the installer to directly position the flap bearing without iterative trial-and-error adjustments. The adjustment aid is configured to be visible and accessible during installation, enabling one-step positioning that achieves precise closure alignment immediately.
2Reliability
If the flap bearing is adjusted iteratively with multiple open/close cycles, then the optimal position is found, but the complexity of the adjustment procedure increases
Solution Approach 1:
The patent introduces an intermediary adjustment aid that mediates between the flap bearing and the installer. This aid (such as a marking, guide rail, or indicator system) provides visual or physical guidance that simplifies the adjustment process. The intermediary element translates the complex geometric relationships into simple, intuitive positioning cues, reducing the procedural complexity while maintaining reliable adjustment outcomes.
3Adaptability or versatility
If the bearing part displacement range is unlimited, then the positioning element can reach any position, but the adjustment precision is reduced
Solution Approach 1:
The patent applies segmentation by dividing the displacement path into distinct segments or zones. The adjustment aid is positioned at specific discrete locations along this path, each representing a predetermined optimal position. The bearing part can be displaced to reach these segmented positions, with each segment corresponding to a specific adjustment state. This segmentation provides both adequate positioning range and precise positioning at key locations.
Solution Approach 2:
The patent applies local quality by providing different characteristics at different locations along the displacement path. The adjustment aid creates zones of high precision at specific positions (where the aid is located) while allowing greater freedom of movement in transition zones. This local differentiation enables the system to maintain adaptability across the full range while achieving high precision at the critical adjustment positions.
