Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door frame operating devices are not versatile enough to adapt to different types and mounting needs, leading to design, production, and storage inefficiencies, as well as increased material and machining costs due to the lack of standardization in handle entry distances and potential errors during mounting.
Innovation Solution
A moving device with an auxiliary body and adjustment means that allows the supporting and containing body to be positioned and adjusted along a specific direction, enabling the same device to be used with various profile configurations and handle pin positions, reducing the need for multiple devices and simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different moving devices are produced for each handle entry distance value, then each device can be precisely adapted to its specific profile type, but design complexity, production costs, and storage management become significantly worsened
Solution Approach 1:
The patent implements a universal moving device design where a single device structure can accommodate multiple handle entry distance values (10mm, 15mm, 30mm, 35mm) through interchangeable positioning elements. The supporting and containing body incorporates multiple predetermined positioning positions that allow the same device to be configured for different profile types, eliminating the need for multiple specialized devices while maintaining precise adaptation to each profile type.

The supporting and containing body incorporates multiple predetermined positioning positions that allow the same device to be configured for different profile types, eliminating the need for multiple specialized devices while maintaining precise adaptation to each profile type.
3Ease of manufacture
If through-holes are made in the profile for mounting the moving device, then the device can be fixed to the profile, but if errors occur in making these holes, the profile must be discarded causing material and machining waste
Solution Approach 1:
The patent incorporates multiple predetermined positioning positions (11a, 11b, 11c, 11d) that are pre-formed in the supporting and containing body during device manufacturing. These pre-formed positions allow for flexible alignment and adjustment during mounting, providing tolerance for minor errors in the through-holes made in the profile. This preliminary preparation of multiple positioning options prevents profile rejection due to minor mounting errors, reducing material waste.
4Volume of moving object
If the reel has a limited diameter due to profile seat constraints, then the moving device can be housed in the profile, but the conjugated surfaces of the teeth are extremely reduced leading to tooth breaking
Solution Approach 1:
The patent replaces the traditional reel-rack gear mechanism with a slider-crank mechanism consisting of a slider (16) that moves linearly within the supporting and containing body, connected to a crank arm (370) that rotates about an offset axis. This dynamic mechanism transformation allows the conversion of linear slider motion into rotational motion of the crank, which then drives the pinion gear. This alternative mechanism eliminates the need for a large-diameter reel, allowing the device to fit within profile constraints while avoiding the tooth surface reduction and breaking issues associated with small-diameter reels.
