Vertical Sliding Element With Scissor Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertical sliding elements, such as windows, are often difficult to operate and have aesthetically undesirable exposed fitting parts when closed, as the necessary components for displaceability remain visible on the inside.
Innovation Solution
A vertical sliding element design featuring a scissor arrangement with guide rails and support rods integrated into a fitting chamber, allowing for parallel parking and easy operation while concealing the guide rails, and incorporating a weight compensation system for smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If guide rails and support rods are integrated into the fitting chamber to conceal them visually, then aesthetic appearance is improved, but device complexity increases
Solution Approach 1:
The guide rails and support rods are nested within the fitting chamber formed between the sash and element frame. The scissor arrangement is integrated into the support rods, creating a compact nested structure that conceals all fitting components within the chamber when the sash is closed, improving aesthetic appearance while maintaining functionality
Solution Approach 2:
Multiple functional components (guide rails, support rods, and scissor arrangement) are merged into a single integrated fitting structure. The guide elements on the support rods combine guiding and support functions, while the scissor arrangement integrates parallel parking capability into the same structural framework, reducing overall complexity despite the concealed design
2Ease of operation
If a scissor arrangement is used for parallel parking the sash, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The scissor arrangement automatically performs the parallel parking action as a preliminary step before vertical displacement. When the user operates the window, the scissor mechanism first parks the sash in front of the opening horizontally, then the guide elements take over for vertical movement, automating the complex maneuver sequence
Solution Approach 2:
The scissor arrangement provides dynamic adaptability by enabling two distinct movement modes (horizontal parking and vertical displacement) through a single mechanism. The mechanism transitions smoothly between different operational states based on the sash position, allowing versatile operation without requiring separate mechanisms for each function
3Stability of the object's composition
If guide elements are made long to maintain parallel alignment during parking, then stability is improved, but the fitting chamber size must increase
Solution Approach 1:
The guide elements utilize the longitudinal dimension of the support rods to achieve parallel alignment during parking. By extending the guide elements along the length of the support rods rather than requiring increased chamber depth or width, the design maintains stability while fitting within compact dimensional constraints
