Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height adjustment apparatus for furniture are often complex to operate, provide insecure support, and pose a risk of the furniture falling over, particularly when used by the elderly, infirm, or disabled individuals.
Innovation Solution
A height adjustment apparatus featuring interconnecting slots with a radial configuration, a rigid support member with fastening means, a window for viewing height adjustment, and a scale for reading additional height, along with a ground-engagable base and connection members for linking multiple units, ensuring secure and adjustable height adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing height adjustment apparatus are used, then height adjustment function is provided, but the apparatus are complicated to operate and provide insecure support
Solution Approach 1:
The apparatus is divided into distinct functional segments: a support member with openings for receiving furniture legs, a height adjustment member with threadable engagement, and an engaging arrangement with resilient deformable material. Each segment performs a specific function, simplifying the overall operation while maintaining security through specialized design of each component.
Solution Approach 2:
The height adjustment member incorporates a threadable mechanism that converts rotational motion into linear displacement, allowing precise control of the engagement depth. The resilient deformable material changes its physical state from flexible to rigid upon engagement, providing secure support while maintaining ease of insertion and adjustment.
2Adaptability or versatility
If existing height adjustment apparatus are used, then height adjustment is provided, but the apparatus pose a risk of furniture falling over
Solution Approach 1:
The support member features openings with specific geometric configurations tailored to different furniture leg types. The engaging arrangement uses locally concentrated resilient deformable material that deforms to match the shape of inserted legs, providing customized secure engagement for each furniture piece while maintaining overall system stability.
Solution Approach 2:
The resilient deformable material exhibits curved or non-linear engagement surfaces that conform to various leg shapes. This curvature allows the engaging arrangement to adapt to different furniture types while maintaining stable contact through distributed pressure points, preventing furniture from falling over.
3Reliability
If a rigid engaging arrangement is used, then secure support is provided, but the apparatus become complicated to operate
Solution Approach 1:
The resilient deformable material automatically adjusts and secures the furniture leg upon insertion without requiring additional fastening operations. The material's inherent elasticity provides self-locking engagement, eliminating the need for complex locking mechanisms while maintaining secure support and simplifying operation to a simple insert-and-adjust motion.
