Spring-Loaded Seat Frame Assembly for Assisted Sitting and Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-cost height adjustable comfort seats do not effectively address the ease of sitting down and standing up, particularly for elderly and individuals with mobility issues, and lack a retrofittable system to enhance these processes on existing couches.
Innovation Solution
A low-cost, height-adjustable seat with a spring-loaded mechanism that includes a frame assembly, legs support assembly, and structure support assembly, where the elastic support absorbs user weight and provides an upward impulse for standing, integrated into an existing couch to improve ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a retrofittable spring-loaded mechanism is added to an existing couch, then the ease of sitting down and standing up is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The invention divides the support system into two separate spring-loaded mechanisms: one integrated into the seat cushion and another attached to the bottom of the couch. This segmentation allows each mechanism to perform a specific function (cushion compression and upward impulse) while maintaining overall system simplicity and retrofitness to existing couches.
Solution Approach 2:
The patent introduces an intermediary elastic support mechanism that mediates between the user's weight and the couch structure. This intermediary component absorbs the shock of sitting and provides the upward impulse for standing, resolving the contradiction by adding functionality without requiring complete system redesign.
2Reliability
If spring-loaded mechanisms are integrated into the seat, then weight absorption and upward impulse are improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent employs simple, inexpensive spring mechanisms that can be easily manufactured and replaced if needed. The use of basic elastic supports rather than complex mechanical systems reduces manufacturing costs while maintaining reliable weight absorption and impulse delivery functionality.
Solution Approach 2:
The spring-loaded mechanisms are designed to automatically perform their functions without external control or complex actuation systems. The springs self-regulate the compression and expansion based on user weight and movement, eliminating the need for expensive sensors, motors, or control electronics while ensuring reliable operation.
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 enhances the ease of sitting and standing for users with mobility issues by providing adjustable height and effective weight absorption and impulse support, while being economically viable and maintainable.
Implementation Method 1
the seating structure has a spring-loaded mechanism that works in concert with another spring-loaded mechanism on the bottom of the couch to springing the user up when standing up and absorbing the weight of the user when sitting down

AI summary
A low-cost height adjustable comfort seat including a frame assembly, legs support assembly, and structure supports assembly. The frame assembly includes a sitting structure with a lower section with inclination angle and a horizontal section. The couch cushion is attached on top of the sitting structure that creates a comfortable seat for the user. Legs support assembly includes adjustable supports in the front and rear side thereof wherein the rear side includes a spring-loaded mechanism. The structure assembly includes back supports attached to the back of the couch to support and absorb the weight of the user by means of structure elastic mechanism coupled between the sitting structure and the back supports, thereby the elastic support in conjunction with the structure elastic mechanism works in concert for sitting and standing up.
