Device for moving a piece of furniture and furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture movement systems, such as drawers and doors, require significant effort to open and close, especially for heavy or large pieces, and do not provide adequate assistance for users with limited strength, like older adults or children.
Innovation Solution
A device with an energy storage mechanism, such as preloaded springs, that assists in opening and closing furniture parts by providing a force support system, allowing for adjustable force levels through separate guide areas, enabling easier operation with minimal effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If standard guide means are used for furniture parts, then the structure is simple, but significant effort is required to open and close heavy furniture parts
Solution Approach 1:
The energy storage device is preloaded during the closing phase to accumulate energy, which is then released during the opening phase to assist with lifting heavy furniture parts. This preliminary action during closing prepares the system to reduce opening effort without adding continuous power consumption.
Solution Approach 2:
The energy storage device acts as an intermediary between the furniture part weight and the user, storing and releasing energy to bridge the force gap. This mediator absorbs the excessive closing force and delivers controlled opening assistance, reducing the contradiction between simple structure and force assistance.
2Ease of operation
If energy storage devices are added to assist opening movement, then opening effort is reduced, but the device complexity increases
Solution Approach 1:
The energy storage device is automatically recharged during the closing movement of the furniture part, eliminating the need for manual intervention or external power sources. The system serves itself by converting the closing motion into stored energy, maintaining ease of operation while managing complexity through automation.
Solution Approach 2:
The system recovers energy during the closing phase that would otherwise be wasted, storing it for reuse during opening. This energy recovery mechanism improves ease of operation by providing assistance when needed most, while the automatic nature of energy recovery keeps the added complexity manageable.
3Adaptability or versatility
If adjustable energy storage is implemented, then adaptability to different furniture parts is improved, but adjustment mechanism complexity increases
Solution Approach 1:
The energy storage device is divided into modular components that can be independently adjusted or configured. This segmentation allows the system to adapt to different furniture part weights and dimensions by adjusting individual modules, improving versatility while keeping the adjustment mechanism complexity manageable through modularity.
Solution Approach 2:
The energy storage device incorporates dynamic adjustment capabilities that allow the preload force to be modified based on the specific furniture part being moved. This dynamic adaptability enables a single device design to handle multiple applications with varying force requirements, improving versatility without proportionally increasing complexity.

AI summary
A device (1) for moving a movable furniture part in an opening direction of the furniture part in relation to a furniture body of a piece of furniture is proposed, wherein the movable furniture part can be brought into the opening direction and into a closing direction via guide means, the device (1) having a an energy storage device accommodated in a bearing part, so that with the assembled device (1) the movable furniture part can be moved under the action of the energy storage device in the opening direction of the movable furniture part, and adjustment means are provided for adjusting the energy storage device. According to the invention, the adjustment means comprise two guide areas that are separate from one another and are adapted to guide an engaging section on the bearing part, the guide areas being displaceable relative to one another in order to specify an area in which the engaging section is received and positioned, the position of the engaging section being determined by the interaction of the both guide areas is determined, so that the position of the engaging portion on the device is dependent on the relative position of the two guide areas to each other.
