Scissor Guide Mount with Rotational Joints for Compact Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scissor-type guides for blinds occupy excessive space when retracted, making it difficult to utilize the space for other purposes and affecting aesthetics, as existing solutions either compromise stability or require additional space for the mount.
Innovation Solution
A mount system for scissor-type guides that includes two rotational mount joints aligned perpendicular to the guide's operation direction, allowing the guide to pack closely by connecting the first end to a bracket and the second end to a tilt bracket, ensuring minimal space usage when retracted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the scissor-type guide is designed to fold compactly, then the space occupied in retracted position is reduced, but the mount structure becomes more complex
Solution Approach 1:
The mount structure is divided into two separate mount members (first mount member and second mount member) that can be independently positioned and adjusted. This segmentation allows each member to be optimized for minimal space occupation while maintaining structural stability, resolving the contradiction between compactness and complexity.
Solution Approach 2:
The scissor-type guide is nested within the mount structure such that when retracted, the guide fits within the footprint defined by the two mount members. The guide members fold within the space bounded by the mount, achieving compact retraction without requiring additional external mounting space.
2Stability of the object's composition
If the mount extends beyond the width of the scissor links, then the scissor-type guide can be mounted stably, but the space efficiency is reduced
Solution Approach 1:
The mount members are designed with different local characteristics - the first mount member extends in one direction while the second mount member extends perpendicular to it. This creates a localized stable base that exactly matches the width of the scissor links, providing stability without excess space occupation.
Solution Approach 2:
Instead of extending the mount in a single dimension beyond the scissor link width, the solution uses two dimensions perpendicular to each other. The first mount member extends along one axis and the second mount member extends along a perpendicular axis, creating a stable L-shaped configuration that bounds the scissor guide width without extending beyond it in any single direction.
3Volume of moving object
If the first end of the scissor-type guide is brought closer to the building opening edge, then the space usage is minimized, but the mounting stability is compromised
Solution Approach 1:
The two mount members are pre-positioned and fixed to the building opening at optimal locations before the scissor-type guide is installed. This preliminary placement ensures that when the guide is mounted and retracted, it achieves maximum proximity to the opening edge while the pre-positioned mount members provide the necessary stability support.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable, compact, and aesthetically pleasing retraction mechanism for scissor-type guides, allowing for efficient use of space and easy maintenance by minimizing the space occupied during the retracted position.
Implementation Method 1
a first end of the first mount member is rotatably connectable to the opening of the building structure via the first rotational mount joint; and a first end of the second mount member is rotatably connectable to the opening of the building structure via the second rotational mount joint
