Adjustable Easel Tilt Linkage for Stable Load Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional easels often collapse under the weight of painting materials due to inadequate structural support, failing to maintain adjusted tilt angles reliably.
Innovation Solution
An easel design featuring a tilting unit with rotatable ends coupled to both the main frame and a supporting frame, along with a guide slot and adjustable components, allows for customizable tilt angle adjustment and stable load distribution, using a protective sleeve to enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rear supporting frame supports the entirety of the load of painting materials, then the structure is simple, but the rear supporting frame may fail to tolerate the load and cause the easel to collapse
Solution Approach 1:
The patent divides the load-bearing function into two segments: the rear supporting frame and the tilting unit. The tilting unit is introduced as a separate component that specifically supports painting materials, while the rear supporting frame provides structural stability. This segmentation allows each component to be optimized for its specific function, preventing the rear supporting frame from being overloaded.
Solution Approach 2:
The tilting unit acts as an intermediary component between the rear supporting frame and the painting materials. It transfers and distributes the load from the painting materials to both the rear supporting frame and the main frame, preventing any single component from bearing the entire load. This intermediary structure resolves the contradiction by adding a load-distributing element without significantly complicating the overall design.
2Adaptability or versatility
If the tilting unit allows adjustment of tilt angle, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The tilting unit incorporates a rotatable connection between the rear supporting frame and the tilting unit itself, allowing the tilt angle to be dynamically adjusted. This dynamic feature enables the easel to adapt to different viewing angles and user preferences. The rotational mechanism is designed to be simple, using basic mechanical components that provide adjustability without excessive complexity.
Solution Approach 2:
The tilting unit is pre-configured with a rotatable joint that allows for preliminary adjustment of the tilt angle before use. This preliminary action capability means the easel can be set up in the desired configuration before placing painting materials, ensuring proper ergonomics and display angle from the start without requiring complex adjustment mechanisms during use.
3Adaptability or versatility
If the other end portion of the tilting unit is detachable and positionable along the guide slot, then the adaptability is improved, but the reliability of maintaining adjusted tilt angle may be affected
Solution Approach 1:
The detachable end portion of the tilting unit that moves along the guide slot incorporates a positioning mechanism with feedback capability. When the user adjusts the position, the mechanism provides tactile or visual feedback to indicate when the desired position is reached. Once positioned, the detachable connection can be secured to maintain that position, ensuring both adjustability and reliable angle maintenance.
Solution Approach 2:
The end portion of the tilting unit is extracted as a detachable component that can be independently positioned along the guide slot. This extraction allows for flexible positioning without compromising the overall structural integrity. The detachable nature enables easy adjustment and repositioning, while the guide slot provides constrained movement paths that ensure reliable maintaining of adjusted positions once set.

AI summary
An easel includes a main frame including a prop in front, a first supporting frame to support the main frame, and a tilting unit. An upper end portion of the first supporting frame is rotatably coupled to the main frame. One end portion of the tilting unit is rotatably coupled to the main frame, the other end portion of the tilting unit is rotatably coupled to the first supporting frame to adjust a tilt angle of the first supporting frame with respect to the main frame and is detachable to be adjustably positioned along a length direction of the first supporting unit. The easel can adjust a tilt angle as desired and reliably maintain an adjusted tilt angle.
