Adjustable Chair Riser Assembly for Easier Standing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chair riser assemblies do not effectively provide a configuration with four corner post assemblies, two width adjustment assemblies, and two chair support assemblies to elevate a chair user's anatomy for easier rising, particularly for individuals with debilitating back, hip, or leg conditions.
Innovation Solution
A chair riser assembly comprising four corner post assemblies, two width adjustment assemblies, and two chair support assemblies, with adjustable height, lateral width, and movement prevention mechanisms to elevate the chair and assist users in rising by adjusting the vertical height and preventing unwanted chair movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a chair riser assembly is designed to elevate the chair height to assist users with mobility issues, then the ease of operation is improved, but the device complexity increases due to multiple corner post assemblies, width adjustment assemblies, and chair support assemblies
Solution Approach 1:
The chair riser assembly is divided into four corner post assemblies, two width adjustment assemblies, and two chair support assemblies. Each corner post assembly functions independently to provide structural support and height adjustment, allowing the complex function of chair elevation to be distributed across multiple simpler modular units that can be manufactured and assembled separately
Solution Approach 2:
The corner post assemblies serve multiple functions: they provide vertical support for chair elevation, enable width adjustment through integrated mechanisms, and offer stability for the overall structure. This multi-functionality reduces the need for separate components for each function, thereby managing complexity while achieving multiple objectives
2Adaptability or versatility
If the chair riser assembly includes width adjustment mechanisms and movement prevention features, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The width adjustment assemblies incorporate movable components that allow the lateral width of the chair riser assembly to be dynamically adjusted. This dynamic capability enables the structure to adapt to different chair sizes and user requirements while maintaining structural integrity through engineered movable joints and locking mechanisms
Solution Approach 2:
The width adjustment assemblies act as intermediary mechanisms between the corner post assemblies, providing a controlled means to modify the lateral dimensions. These intermediary components facilitate adaptability without requiring complete redesign of the entire structure, managing complexity by isolating adjustment functions to specific intermediate elements

AI summary
A chair riser assembly supports a chair in an elevated position relative to a primary support surface for providing the chair user with a slightly raised seat elevation for aiding the chair user in rising from the riser-supported chair. The chair riser assembly includes a series of corner post assemblies each of which have a lower post end for engaging the primary support surface. Two width adjustment assemblies adjustably interconnect paired, laterally spaced the post assemblies for enabling the user to adjust the lateral width of the riser assembly for accommodating variously sized chairs. Laterally opposed chair support assemblies interconnect forward portions of the chair riser assembly to rearward portions of the chair riser assembly. Each chair support assembly includes a chair support portion in superior adjacency to the lower post ends for supporting lower portions of the chair in superior adjacency to the primary support surface.
