Case Clamp Base Frame Design for Furniture Carcass Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing case clamps for furniture carcasses have complex structural designs that hinder accessibility and require significant space, as they include bulky upright support frames and multiple compression beams.
Innovation Solution
A simplified case clamp design that eliminates the upright support frame by supporting all components exclusively on a base frame, using guide elements like guide rails for load dissipation, and integrating a servo-drive and counterweight to manage forces, allowing for horizontal and vertical traversability of compression beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an upright support frame with multiple compression beams is used, then the case clamp can bear the necessary loads during clamping, but the structural design becomes complex and bulky, reducing accessibility and increasing space requirements
Solution Approach 1:
The patent removes the upright support frame from the case clamp structure. Instead of having a traditional vertical support frame with multiple compression beams, the invention uses a base frame with supports that are traversable horizontally, eliminating the need for the complex upright structure while maintaining load-bearing capability through a simplified base frame configuration
Solution Approach 2:
The patent divides the support function into separate components: a base frame that provides horizontal support and multiple supports that can be traversable horizontally. This segmentation allows each component to perform its specific function more efficiently, with the base frame handling horizontal loads and the traversable supports providing vertical support where needed, reducing overall structural complexity
2Strength
If an upright support frame with multiple compression beams is used, then the case clamp can bear the necessary loads during clamping, but the case clamp becomes bulky and heavy, increasing space requirements
Solution Approach 1:
The patent removes the upright support frame and associated compression beams from the structure. By extracting these heavy components and replacing them with a base frame and traversable supports, the overall weight of the case clamp is significantly reduced while maintaining the necessary load-bearing capacity through a more efficient structural configuration
3Stability of the object's composition
If an upright support frame is used, then the case clamp can provide stable support, but accessibility to the case clamp is hindered
Solution Approach 1:
The patent removes the upright support frame that was blocking access to the case clamp. The remaining structure, consisting of a base frame with traversable supports, provides sufficient stability without the bulky vertical components that previously hindered accessibility, allowing operators easier access to the clamping mechanism
4Strength
If an upright support frame with multiple compression beams is used, then the case clamp can provide comprehensive support, but the requirement for space is maximized
Solution Approach 1:
The patent removes the upright support frame and associated compression beams that occupied significant vertical and horizontal space. The simplified base frame with traversable supports provides the necessary support capability in a much more compact configuration, significantly reducing the space required for the case clamp while maintaining structural integrity
