Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door operating systems experience disruptive friction due to connecting rods and angle drives, making them inconvenient to operate and lacking remote-controlled functionality.
Innovation Solution
A hydraulic or pneumatic actuating device is integrated into the window or door frame, using existing cavities to guide actuating fluid through channels, allowing for adjustable locking elements to switch between operating states without friction, enabling remote-controlled operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connecting rods and angle drives are used for window operation, then mechanical actuation is achieved, but friction occurs and operation becomes inconvenient
Solution Approach 1:
The patent replaces the traditional mechanical connecting rod and angle drive system with a hydraulic actuation system. The hydraulic cylinder with piston and rod directly actuates the locking mechanism, eliminating the need for complex mechanical linkages that generate friction. This substitution of mechanical systems with hydraulic systems resolves the contradiction by removing the friction-generating components while maintaining the actuation function.
Solution Approach 2:
The patent implements a hydraulic actuation system using a hydraulic cylinder, piston, and fluid pressure to operate the window locking mechanism. The hydraulic fluid transmits force through channels in the profile structure, enabling friction-free actuation of the locking elements. This application of hydraulics directly addresses the friction problem by replacing mechanical contact-based actuation with fluid-based force transmission.
2Ease of operation
If connecting rods and angle drives are used, then window actuation is achieved, but operation becomes cumbersome and remote control is difficult
Solution Approach 1:
The patent replaces the complex mechanical operating system with a hydraulic actuation system that can be more easily integrated with remote control mechanisms. The hydraulic cylinder and piston system requires simpler control inputs compared to mechanical linkages, enabling easier remote actuation through proportional valves or simple on/off control of hydraulic fluid flow.
Solution Approach 2:
The hydraulic actuation system serves multiple functions: it provides the actuating force for locking/unlocking, can be integrated with remote control systems, and allows for variable control (manual or automated). This multi-functionality reduces the need for separate mechanical systems for different operations, simplifying the overall device while improving ease of operation and remote control capability.
3Reliability
If hydraulic actuating device is integrated using existing cavities, then friction is reduced and remote control is enabled, but additional effort is required for fluid guidance
Solution Approach 1:
The patent makes the profile cavities serve dual functions: their original structural purpose and as fluid guidance channels for the hydraulic system. By designing the profile structure with integrated channels that guide hydraulic fluid from the actuator to the locking elements, the system eliminates the need for separate fluid distribution components. This multi-functional use of existing cavities reduces manufacturing complexity while maintaining reliable hydraulic actuation.
Solution Approach 2:
The patent merges the structural profile with the hydraulic fluid guidance system by integrating channels directly into the profile cavities. This combination of structural and functional elements into a single integrated component simplifies manufacturing compared to adding separate fluid guidance systems, while ensuring reliable hydraulic actuation for friction-free operation and remote control capability.
