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

VSEngineering 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

Engineering Contradiction:
Improveaesthetic appearanceVSAvoiddevice complexity
Core Design Contradiction:
ShapeVSDevice complexity

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

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a scissor arrangement is used for parallel parking the sash, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
ImprovestabilityVSAvoidfitting chamber size
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
