Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blender jar locking mechanisms fail to effectively restrict vertical movement while allowing for rotational and linear movement, leading to inefficiencies and wear during food processing.
Innovation Solution
A cylindrical jar lock with radially inwardly extending locking tabs and a collar design that engages with the jar, allowing for vertical restraint while permitting rotational and linear movement, coupled with a spring-mounted mechanism for dampened vertical motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid fixed mounting is used to prevent vertical movement, then vertical stability is improved, but rotational and linear movement are restricted
Solution Approach 1:
The jar lock transitions from a static fixed mounting to a dynamic spring-mounted configuration that adapts its constraint level based on operational needs, allowing vertical restraint during blending while permitting rotational and linear movement during assembly and cleaning
2Adaptability or versatility
If a spring-mounted mechanism is used to allow vertical motion, then rotational and linear movement are improved, but vertical stability deteriorates
Solution Approach 1:
The spring constant and pre-load force are carefully selected to provide sufficient vertical restraining force during blending operation while allowing controlled vertical displacement during assembly and disassembly, effectively changing the constraint parameters based on operational phase
3Reliability
If locking tabs are made rigid to prevent vertical movement, then vertical locking reliability is improved, but wear during operation increases
Solution Approach 1:
The locking tabs are designed with flexible material properties that allow elastic deformation during engagement and disengagement, reducing impact forces and wear while maintaining sufficient rigidity to prevent vertical movement during blending operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures secure vertical locking, reduces wear, and allows for efficient rotational and linear movement, enhancing the blender's operational efficiency and durability.
Implementation Method 1
A cylindrical jar lock is spring-mounted to the base, with the cylindrical jar lock positioned radially outwardly from the lower coupler and permitted to move over a predetermined vertical range with respect to the base

AI summary
A food processing machine having a base and a cylindrical jar lock extending upwardly from a top surface of the base. A jar assembly has a jar and a collar that extends downwardly from the jar. The collar is adapted to fit circumferentially around the cylindrical jar lock. A plurality of locking tabs extend radially inwardly from the collar. The locking tabs engage with the cylindrical jar lock and prevent vertical movement of the jar while allowing rotational movement of the jar and linear movement of the jar with respect to the base in the xy-plane. The cylindrical jar lock is optionally spring-mounted to the base to provide dampened movement in the vertical direction of the cylindrical jar lock with respect to the base.
