Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable furniture designed for specific applications, such as racing simulations, is often space-consuming and lacks versatility for all-purpose use without disassembly.
Innovation Solution
A locking device for furniture that includes a rotatable axle with an engagement recess limited to a predetermined angular segment, a blocking element, and an adjusting ring with a contoured recess for radial adjustment, allowing for both free rotation and secure locking by engaging the blocking element in the engagement recess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If furniture is designed to be rotatable for all-purpose use, then versatility is improved, but stability for specific applications deteriorates
Solution Approach 1:
The locking device enables the furniture to dynamically switch between two states: a rotatable state for all-purpose use and a locked state for stable specific applications. The blocking element can be radially adjusted to engage with or disengage from the engagement recess, allowing the furniture to transition between stable and versatile configurations as needed.
Solution Approach 2:
The angular extent of the engagement recess is limited to a predetermined segment, which changes the geometric parameter of the locking mechanism. This limited angular segment provides sufficient stability for specific applications while allowing the furniture to be rotated to different positions for versatile use, resolving the contradiction between stability and adaptability.
2Stability of the object's composition
If furniture is designed as fixed for specific applications, then stability is improved, but adaptability for all-purpose use deteriorates
Solution Approach 1:
The locking device transforms fixed furniture into dynamically adjustable furniture. By radially adjusting the blocking element, the furniture can switch between a fixed stable configuration for specific applications and a rotatable versatile configuration for all-purpose use, eliminating the need for disassembly.
Solution Approach 2:
The locking device enables the furniture to serve multiple functions: it can be locked in a stable position for specific applications like racing simulations, or unlocked for rotatable use in all-purpose settings. This multi-functionality resolves the contradiction between stability and adaptability.
3Stability of the object's composition
If a locking mechanism is added to rotatable furniture, then stability for specific applications is improved, but device complexity deteriorates
Solution Approach 1:
The locking device is segmented into distinct functional components: the engagement recess in the axle, the blocking element, the support bearing, and the adjusting mechanism. This segmentation allows each component to perform its specific function simply, reducing overall complexity while providing stable locking capability.
Solution Approach 2:
The support bearing acts as an intermediary that guides the blocking element's radial movement while maintaining rotational support. This intermediary component simplifies the locking mechanism by providing a dedicated guide path, reducing the complexity of achieving stable locking without compromising the rotatable functionality.

AI summary
A locking device for furniture, in particular for furniture which may be adjusted by rotation of a furniture section is provided. The locking device includes an axle which is rotatable for adjusting the furniture and which has an engagement recess limited to an angular segment about the axle. The locking device further includes a blocking element which is configured for rotational blocking of the axle by engaging in the engagement recess. The locking device further includes a support bearing which is configured to support the blocking element in a fixed rotational manner about the axle. The locking device further includes an adjusting ring rotating about the axle, which has a contoured recess for radial adjustment of the blocking element within the support bearing upon rotation of the adjusting ring about the axle. The blocking element is engageable in the engagement recess by the radial adjustment, so that the axle is lockable rotationally with the support bearing via the blocking element.
