Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Woodworking machine tools face inefficiencies and operational challenges due to the buckling of elastic elements and increased wear caused by machining chips, which affect the precision and longevity of the tools.
Innovation Solution
A woodworking machine tool device with a pre-alignment unit featuring a housing unit that encloses an elastic element, providing a stable and secure environment for the elastic element, and a clamping unit with a receiving element for efficient tool positioning and alignment, utilizing a spring plunger or ball plunger design for cost-effectiveness and ease of maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If elastic elements are used in pre-alignment units, then tool positioning and alignment are improved, but buckling and wear from machining chips reduce reliability
Solution Approach 1:
The pre-alignment unit is divided into separate functional components: the elastic element (spring plunger or ball plunger) is separated from the clamping function, allowing each component to be optimized independently. The elastic element focuses solely on positioning and alignment, while separate clamping elements handle securing the tool, preventing interference between functions that would cause buckling and wear.
Solution Approach 2:
The patent introduces intermediate structural elements such as housing units that enclose and protect the elastic elements from machining chips. These housing units act as intermediaries between the elastic elements and the harsh machining environment, preventing direct contact with chips that would cause wear and buckling.
2Ease of operation
If elastic elements are exposed for functionality, then ease of operation is improved, but wear from machining chips increases
Solution Approach 1:
The patent employs housing units with openings or flexible covers that allow the elastic elements to perform their alignment function while protecting them from machining chips. The housing may include chip-resistant materials or designs that let the elastic element move freely for alignment purposes while blocking harmful chips.
3Stability of the object's composition
If clamping force is increased to secure tools, then holding stability is improved, but elastic element buckling increases
Solution Approach 1:
The clamping function is separated from the pre-alignment function. Independent clamping elements apply securing force to the tool, while the elastic elements in the pre-alignment unit are relieved from bearing clamping loads, preventing buckling while maintaining tool holding stability.
Solution Approach 2:
The patent distributes clamping forces across multiple dimensions and contact points using separate clamping elements, rather than concentrating all clamping force on the elastic elements. This multi-point clamping approach provides stable tool holding without overloading any single elastic element.
