Adjustable Stop for Portable Wood Cutting Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wood cutting technologies are inefficient for cutting large quantities of wood uniformly and repeatably, particularly when portability and space for cutting are limited, as they require manual measurement and are not easily movable.
Innovation Solution
An adjustable stop system with a spring biasing member and portable table assembly that allows for quick and precise cutting of wood to uniform lengths, eliminating the need for individual measurement and enabling easy movement and expanded cutting space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed bench saws are used for cutting wood, then cutting precision and stability are improved, but portability and ease of movement deteriorate
Solution Approach 1:
The saw system is divided into separate modular components: a portable saw unit with its own base and handle, and a separate adjustable table assembly. This segmentation allows the saw to be easily transported while maintaining cutting precision through the modular connection to the stable table surface when assembled.
Solution Approach 2:
The table assembly incorporates adjustable and movable components including height-adjustable legs with locking mechanisms, an adjustable stop mechanism with spring biasing, and a table surface that can be positioned at different angles. These dynamic features allow the system to adapt to different working conditions while maintaining stability during cutting operations.
2Adaptability or versatility
If traditional manual measurement and marking is used for each piece of wood, then flexibility in cutting different lengths is improved, but productivity and time efficiency deteriorate
Solution Approach 1:
The adjustable stop mechanism is pre-configured with measurement markings and spring-biased positioning features that allow rapid setting to predetermined lengths. This preliminary preparation of measurement references eliminates the need for repeated manual measurement and marking, enabling fast adjustment between different cutting lengths while maintaining accuracy.
Solution Approach 2:
The spring-biased stop mechanism automatically maintains contact with the workpiece and provides tactile feedback for proper positioning. The self-adjusting nature of the stop with its spring loading system reduces the operator's effort and time required to set and verify each cutting position, thereby increasing productivity.
3Ease of operation
If mobile saws carried by multiple individuals are used, then portability is improved, but device complexity and difficulty of setup deteriorate
Solution Approach 1:
The system separates the heavy saw mechanism from the table assembly, allowing the saw to be carried individually while the table can be assembled on-site. This segmentation reduces the burden on individual carriers and simplifies the overall setup process compared to moving and assembling a complete integrated system.
Solution Approach 2:
The table assembly features collapsible legs with locking mechanisms and adjustable components that can be quickly configured. The dynamic design allows for rapid assembly and disassembly by a single person, reducing setup complexity while maintaining portability and stability during use.

AI summary
An adjustable device for cutting an object has a frame with a back member that extends between a pair of feet. The feet are adjustably connected to a work bench or portable work table assembly. A spring biasing member has a back plate and a pair of side rods that extend from the back plate, through the back member, and are connected to a front member. A plurality of spacers are positioned between the front and back members.
