Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a portable, hand-operated crushing apparatus that can crush small rocks and ores to a minus 20 mesh size in three or less passes without requiring electricity or fuel, and is lightweight enough to be transported to remote areas for ore discovery and processing.
Innovation Solution
A manually operated portable jaw crusher with adjustable jaws and a simple leveling system, allowing for effective crushing and grinding of small rocks and ores, featuring a non-rotating shaft for the movable jaw and a stationary jaw that can be adjusted to control the output size, designed for use in areas without electricity or fuel, and suitable for mounting on vehicles or stable surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a portable crushing apparatus is designed to be lightweight and hand-operated, then ease of transport and portability are improved, but crushing power and processing capability deteriorate
Solution Approach 1:
The patent employs a dynamic lever mechanism where the movable jaw is actuated by a lever arm that pivots on a fixed pivot point. This lever system multiplies the applied force dynamically, allowing a lightweight hand-operated device to generate sufficient crushing power. The lever arm rotates through an arc, converting vertical hand motion into horizontal crushing force at the jaw interface.
Solution Approach 2:
The crushing apparatus is segmented into distinct functional components: a stationary jaw, a movable jaw actuated by a lever, and a crushing chamber. This segmentation allows each component to be optimized independently - the jaws for crushing efficiency while the lever mechanism provides mechanical advantage without requiring a heavy overall structure.
2Productivity
If the apparatus is designed to achieve fine grinding (minus 20 mesh) in three or less passes, then productivity is improved, but device complexity increases
Solution Approach 1:
The lever mechanism provides dynamic control over the crushing process, allowing the operator to adjust the degree of compression and control the reduction ratio. This dynamic adjustment capability enables fine grinding in fewer passes by optimizing the crushing action for each pass rather than requiring multiple fixed-stage processing steps.
Solution Approach 2:
The patent utilizes parameter changes in the lever mechanism - specifically the pivot point position, lever arm length, and jaw geometry - to control the crushing parameters. By adjusting these parameters, the device can achieve consistent fine grinding results (minus 20 mesh) in three or less passes without requiring complex multi-stage machinery.
3Adaptability or versatility
If the apparatus is designed for use in remote areas without electricity or fuel, then adaptability to harsh environments is improved, but operational limitations worsen
Solution Approach 1:
The lever mechanism is designed to provide mechanical advantage that reduces the effort required for hand operation. The pivot point and lever arm configuration create a mechanical advantage ratio that amplifies the operator's input force, making hand operation feasible even in remote areas without electrical or fuel power sources.
Solution Approach 2:
The apparatus is designed as a self-contained mechanical system that requires no external power sources. The lever mechanism stores and transmits mechanical energy through pure mechanical means, making the device self-sufficient for operation in remote areas where electricity and fuel are unavailable.
