Keyboard Stand Connector Geometry for Wall-Contact Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stands require increased rigidity to prevent deformation when legs are forced against a wall, often compromising design aesthetics.
Innovation Solution
A stand design featuring a horizontal spanning member, polygonal connectors, and leg members with angled cross sections and fixed attachments to enhance rigidity and maintain design integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If legs are forced against a wall surface to provide stability, then the stand achieves positional stability, but the leg rigidity must be increased which compromises design aesthetics
Solution Approach 1:
The connector is divided into multiple functional portions: a polygonal portion for leg attachment, a horizontal spanning member fixation portion for structural support, and an adjustable positioning mechanism. This segmentation allows each part to optimize its function without requiring excessive overall rigidity.
Solution Approach 2:
The stand incorporates an adjustable mechanism that allows the lower end of the leg to be positioned at multiple heights relative to the wall surface. This dynamic adjustment capability enables the stand to adapt to different stability requirements without permanently increasing leg rigidity.
2Strength
If leg rigidity is increased to prevent deformation when forced against walls, then structural strength is improved, but design aesthetics are compromised
Solution Approach 1:
The connector has different portions with different functional qualities: the polygonal portion provides rigid attachment points for legs, while the horizontal spanning member fixation portion provides structural support. This local differentiation allows rigidity to be concentrated where needed rather than uniformly distributed, preserving overall aesthetic design.
Solution Approach 2:
The connector acts as an intermediary element between the legs and the horizontal spanning member, distributing mechanical stresses and forces. This mediator function allows the legs to maintain their aesthetic design while still providing sufficient rigidity through the connector's structural support.
