Seat adjustment module, seat frame, and seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seats, such as office chairs and gaming chairs, require multiple adjustment mechanisms that can confuse users, leading to erroneous adjustments and a poor user experience due to their complexity.
Innovation Solution
An integrated seat adjustment module that includes a base with a stop block, a rotary block, a handle, and a twistable adjustment member, allowing for coordinated adjustments of seat height, reclining angle, and backrest elasticity through a compact and stable transmission mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adjustment mechanisms are arranged on the seat to achieve different adjustment functions, then the adaptability and functionality of the seat is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple adjustment mechanisms (seat cushion position adjustment, backrest angle adjustment, and lumbar support adjustment) into a single integrated adjustment module. This module includes a base, stop block, rotary block, and transmission member that work together to control multiple adjustment functions simultaneously, reducing the number of separate mechanisms from three or more to one unified system.
Solution Approach 2:
The adjustment module is designed as a universal mechanism that can perform multiple adjustment functions through a single operational interface. The rotary block can rotate in different directions to trigger different adjustment actions: first rotation direction controls seat cushion position, second rotation direction controls backrest angle, and third rotation direction controls lumbar support. This multi-functional design eliminates the need for multiple separate controls.
2Adaptability or versatility
If multiple adjustment members are arranged on the seat to achieve adjustments in cooperation with different adjustment mechanisms, then the adaptability is improved, but the ease of operation deteriorates due to user confusion
Solution Approach 1:
The adjustment module provides a single universal control interface (the rotary block) that handles all adjustment functions. Users interact with one component rather than multiple separate adjustment members, eliminating confusion about which control to use for which function. The rotary block's multi-directional rotation capability provides intuitive control over different adjustment parameters.
Solution Approach 2:
The transmission member acts as an intermediary that translates the rotary block's rotation in different directions into specific adjustment actions. This mediation simplifies the user interface by providing a single control element while internally distributing the control signals to the appropriate adjustment mechanisms through the transmission member's directional response.
3Adaptability or versatility
If multiple adjustment members are arranged on the seat, then the adaptability is improved, but reliability deteriorates due to erroneous adjustments
Solution Approach 1:
By providing a single universal control interface, the patent eliminates the possibility of users mistakenly operating the wrong adjustment mechanism. The rotary block's design with distinct rotation directions ensures that each user input is deliberately directed to a specific function, preventing erroneous adjustments that could occur with multiple independent controls.
Solution Approach 2:
The adjustment module incorporates feedback mechanisms where the transmission member responds to the rotary block's rotation direction and the adjustment mechanisms provide tactile feedback to confirm the intended action. This feedback loop ensures that user inputs are correctly interpreted and executed, preventing erroneous adjustments by confirming the intended function before execution.

AI summary
A seat adjustment module includes: a base; a stop block, configured to stop forward and backward movements of a seating member in a seat; a rotary block, configured to, in response to being rotated along a first rotation direction, drive the stop block to slide, wherein the rotary block is further configured to, in response to being rotated along a second rotation direction, open a backrest adjustment switch in the seat; a handle, rotatably connected to one end of the rotary block, and configured to, in response to being rotated with respect to the rotary block, open a lifter switch of the seat; and a twistable adjustment member, rotatably connected to the base, and configured to be connected to a backrest elastic force adjustment mechanism, wherein the twistable adjustment member is configured to adjust a magnitude of an elastic force of a backrest in the seat.
