Seat Support Structure With Bilateral Handles for Assisted Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elderly and individuals with low core or leg strength face challenges in getting up from seated positions due to the lack of bi-lateral arm support and firm seating in many chairs and couches, leading to potential injuries and inconvenient solutions.
Innovation Solution
A seat support device featuring a substantially rigid base sheet with two vertically extending arm supports, each forming a cushion receiving region and a support handle, providing both arm and seat support to aid in rising from a seated position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a couch has only one arm support per seat or no arm supports, then the couch structure remains simple and soft, but it becomes difficult for elderly or weakened individuals to get up because they have nothing to brace themselves on
Solution Approach 1:
The arm support is divided into multiple functional segments: a rigid base sheet providing structural foundation, vertical arm supports for upper body bracing, and horizontal support handles at armrest level for hand placement. This segmentation allows each component to perform its specific function optimally while working together to solve the problem of difficult rising.
Solution Approach 2:
The invention adds vertical dimension to the traditionally horizontal armrest concept by incorporating vertically extending arm supports that provide both upper body bracing and handhold surfaces at different heights, creating a multi-level support structure that addresses the difficulty of rising from seated position.
2Ease of operation
If couches and chairs are low and soft, then they provide comfort for sitting, but they require users to rise further from seated to standing position with less support, adding to the difficulty
Solution Approach 1:
The base sheet is designed with differentiated local qualities: a rigid central area beneath the cushion for structural support and firmness, and potentially flexible edges for comfort. This local differentiation allows the seat to provide both comfort during sitting and firm support during the rising action.
Solution Approach 2:
The rigid base sheet and arm supports are pre-positioned to provide immediate structural support as soon as the user begins the rising motion. The support handles are预先 positioned at optimal heights and locations to enable the user to grasp them early in the rising sequence, before full body weight needs to be supported.
3Ease of operation
If a stand frame extends partially under the couch to provide something to grab onto, then it helps greatly in getting up, but it can be extremely dangerous as a tripping hazard because it may get caught under one's feet
Solution Approach 1:
The harmful extending frame structure is extracted and replaced by integrating support elements directly onto the seat surface. The arm supports and support handles are positioned within or above the seat footprint, eliminating the need for external extending structures that could become tripping hazards while maintaining the grab-and-rise function.
4Ease of operation
If the stand frame does not provide any seat support, then it avoids adding complexity, but seat softness continues to be a challenge for weakened individuals
Solution Approach 1:
The invention merges multiple functions into a single integrated base sheet structure: cushion support, structural firmness provision, and attachment point for arm supports. This consolidation provides seat support and rising assistance simultaneously without requiring separate complex mechanisms, as the rigid base sheet inherently provides both cushion stabilization and structural support.

AI summary
A seat support device is provided. The seat support is configured to receive a seat cushion and provide support to the cushion as well as providing two support handles above the cushion. The combination of these elements allows an elderly, disabled, or otherwise weakened person to easily rise from a seated to standing position.
