Rectangular frame with height adjustment for a first and/or second device for coupling to the frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rectangular frames rigidly connect devices such as desks, black/whiteboards, or paintings to the frame, limiting their adjustability and versatility.
Innovation Solution
The frame incorporates adjustable coupling means with constant-force springs and cords, allowing for height adjustment of devices on both sides, along with a braking system for locking positions, enabling flexible placement and application across various surfaces and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a device is rigidly connected to the frame, then structural stability is improved, but height adjustability deteriorates
Solution Approach 1:
The coupling means are designed to be dynamically adjustable in height along the uprights while maintaining stable connection. The coupling elements can move vertically along the uprights and remain securely connected through the cord and adjusting means, allowing the system to transition between fixed and adjustable states as needed.
2Adaptability or versatility
If height adjustment mechanism is added, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjusting means utilize constant-force springs that automatically provide the necessary tension and force for height adjustment without requiring external power sources or complex control systems. The mechanism serves itself by using the spring's inherent mechanical properties to enable smooth, controlled movement of the coupling elements along the uprights.
Solution Approach 2:
Cords serve as intermediaries connecting the coupling elements to the adjusting means, transmitting force and enabling height adjustment. This intermediary approach simplifies the overall mechanism by using flexible cords rather than rigid mechanical linkages, allowing for easier movement and adjustment.
3Adaptability or versatility
If multiple devices are coupled to opposite sides of the frame, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The frame is designed with symmetric coupling means on both uprights that can couple devices to either side. The same coupling mechanism (coupling element, cord, and adjusting means) can be used for devices on opposite sides, allowing a single frame design to serve multiple applications such as desks, whiteboards, or paintings on either side without requiring different manufacturing processes.

Function Achieved in This Case
This solution provides a versatile, height-adjustable frame that can be used for multiple applications without electricity, ensuring uniform force application and easy installation, while allowing for secure locking of devices at desired heights, enhancing usability and economic production.
Implementation Method 1
The first adjusting means comprise at least one constant-force spring, wherein a first outer end of each constant-force spring is connected to both the first and the second cord
Implementation Method 2
the correct force springs can be chosen subject to the weight of the device in order to enable movement of the device in the height using the spring force of the constant-force springs and gravitational force
Implementation Method 3
each constant-force spring or a set of constant-force springs is preferably provided with a brake which engages on the constant-force spring
