Standing Seat Structure With Flexible Front Zone for Sitting Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seats are uncomfortable and physiologically disadvantageous, causing users to constantly change their sitting position due to hard surfaces that do not adequately support the ischial tuberosity, leading to discomfort and a desire for alternative seating.
Innovation Solution
A seat design featuring a seat carrier with a rear area lower than the front area, where the rear area supports the seat bones and the front area is designed as a flexible zone without direct supports, incorporating a cantilever arm and elastic materials to enhance comfort and prevent pressure points, with a support strut to limit deflection and distribute forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seat is designed with a hard surface and direct supports throughout, then structural strength is improved, but comfort and physiological suitability deteriorate
Solution Approach 1:
The seat plate is segmented into different functional zones: a rigid rear area with direct support for the ischial tuberosity, and a flexible front area without direct supports. This segmentation allows each zone to provide its specific function - structural strength where needed and comfort where required
Solution Approach 2:
Different areas of the seat plate are given different mechanical properties. The rear area is designed to be rigid and supportive, while the front area is designed to be flexible and yielding. This local differentiation of quality resolves the contradiction by providing strength where structurally necessary and comfort where physiologically beneficial
2Ease of operation
If the front area is made completely flexible without supports, then comfort is improved, but structural stability deteriorates
Solution Approach 1:
Instead of providing complete support across the entire seat plate, the invention applies support selectively - rigid supports in the rear area and no direct supports in the front area. This partial application of support structure achieves the desired flexibility in the front while maintaining overall stability through the supported rear portion
3Stability of the object's composition
If support struts are added to limit deflection, then structural stability is improved, but complexity of construction increases
Solution Approach 1:
The support struts are merged with the seat plate structure itself, forming an integrated component rather than separate attachments. The seat plate is designed with built-in support struts that are structurally continuous with the plate, simplifying construction while providing the necessary stability
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 seat provides optimized support and comfort by allowing slight adjustments in sitting position, improving blood circulation and reducing pain from edge pressure, while maintaining mechanical stability and preventing damage through strategic design elements like radially softer lamellar arms and a V-shaped arrangement.
Implementation Method 1
An elastic material is advantageously arranged between the at least one support strut and the flexible zone. This not only relieves the load on the support strut, but also serves as a kind of damping means to limit the movement or to prevent the flexible zone from springing back into its rest position.
Implementation Method 2
An elastic material is advantageously arranged between the at least one support strut and the flexible zone. This not only relieves the load on the support strut, but also serves as a kind of damping means to limit the movement or to prevent the flexible zone from springing back into its rest position.

AI summary
A seat comprising a seat support for receiving and bracing a seat plate, which comprises a rear region and a front region, the rear region, which receives the ischial bones (os ischii), being arranged lower than the front region and the seat support supporting the rear region, wherein the front region of the seat plate is formed resiliently as a flexible zone without direct supports.
