Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for manufacturing laminated wood bent elements are limited in their ability to produce different bending profiles without requiring separate molds for each profile, making it difficult to efficiently manufacture various shapes such as arches, S-shaped elements, and other complex forms.
Innovation Solution
A device featuring a working board with a grid of regularly spaced fixing holes and adjustable clamps, where each clamp has a retaining plate and clamping plate connected by hydraulic cylinders, allowing for precise positioning and bending of laminated wood elements into various shapes by arranging clamps according to the desired curvature, enabling the production of multiple shapes on a single board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate molds are used for each bending profile, then manufacturing precision for specific shapes is improved, but device complexity and production time increase
Solution Approach 1:
The patent implements a universal bending device with adjustable clamps that can produce multiple bending profiles (arches, S-shaped elements, etc.) on a single working board. The clamps can be repositioned along guide rails to different coordinates, allowing the same device to create various curvature profiles without requiring separate molds for each shape.
Solution Approach 2:
The device employs dynamically adjustable clamps that can be moved to different positions along the working board's guide rails. This dynamic repositioning capability allows the clamps to adapt to different bending profile requirements, transforming a static mold system into a flexible, multi-functional system.
2Manufacturing precision
If multiple separate devices are used for different shapes, then manufacturing precision for each shape is maintained, but productivity decreases
Solution Approach 1:
The patent creates a single multi-functional device that can produce various bent wood elements (arches, S-shaped profiles, etc.) on one working board. This eliminates the need to switch between multiple dedicated devices, thereby maintaining shape accuracy while significantly improving production efficiency.
Solution Approach 2:
The invention merges multiple shape-specific functions into a single device by combining adjustable clamps, guide rails with coordinate markings, and a unified working board. This consolidation allows different bending profiles to be produced on one device rather than requiring separate devices for each profile type.
3Manufacturing precision
If fixed molds are used for bending, then manufacturing precision is improved, but adaptability to different profiles deteriorates
Solution Approach 1:
The patent replaces fixed molds with dynamically repositionable clamps that can be moved along guide rails to different coordinates. This dynamic system maintains bending consistency through precise positioning while enabling adaptation to various profiles by simply repositioning the clamps rather than changing entire mold structures.
Solution Approach 2:
The device segments the bending process into controllable sections by using multiple independent clamps that can be positioned at different locations along the working board. Each clamp can be independently adjusted to create specific curvature sections, allowing complex profiles like S-shaped elements to be constructed from multiple segmented bends.

Enables the simultaneous bending and pressing of laminated wood elements into diverse profiles, including arches and S-shaped elements, on a single device, allowing for efficient production of complex shapes without the need for multiple molds, and allows for the extension of working boards to accommodate larger dimensions.
Implementation Method 1
Each clamp comprises a bottom beam to which a retaining plate with the screw is fixed, perpendicular to the bottom beam and a clamping plate perpendicular to the bottom beam are attached. The clamping plate is slidably attached in the clamp by means of a screw.
