Solution Overview
Problem
There is a need for an improved and efficient motor that can provide rotational or other movement to an externally connected device by utilizing a plurality of power units and/or springs alternately disposed between compressed and relaxed states to produce power.
Innovation Solution
A spring drive apparatus with a rotatable cam shaft having cams with varying edge distances, rocker arms, and expansible, compressible connecting means, where the cam shaft's rotation and the reciprocal movement of the connecting means deliver continuous independent spring force for rotation, with the hydraulic pump aiding in the operation and control of the throttle system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single spring is used to drive the motor, then the structure is simple, but the motor cannot provide continuous rotational energy
Solution Approach 1:
The motor divides the driving system into multiple independent spring units (first spring, second spring, third spring, fourth spring) arranged around the cam shaft. Each spring unit operates independently to push the rocker arm assembly, ensuring that while one spring is compressing, others are expanding to provide continuous rotational force to the crank shaft.
2Duration of action of moving object
If multiple springs are used to provide continuous power, then continuous rotational energy is achieved, but the device complexity increases
Solution Approach 1:
The motor combines multiple spring units with a shared cam shaft, rocker arm assembly, and crank shaft system. All four springs work together through the common mechanical linkage, where the cam shaft converts the reciprocating motion of multiple springs into continuous rotational motion of the crank shaft, achieving efficient power synthesis.
Solution Approach 2:
The motor utilizes periodic compression and expansion cycles of multiple springs arranged in sequence. As the cam shaft rotates, it sequentially activates each spring unit, ensuring that at least one spring is always in the expansion phase delivering power to the crank shaft, while others are in compression or idle phases, creating continuous periodic power delivery.
3Productivity
If the cam shaft rotates continuously, then power transmission is efficient, but the spring must be constantly compressed and expanded
Solution Approach 1:
The spring units are pre-compressed to store elastic potential energy before the motor operates. This preliminary compression allows the springs to immediately deliver power when activated by the cam shaft, eliminating the need for continuous external compression and enabling self-sustaining operation where the expanding springs drive the crank shaft rotation.
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 apparatus ensures continuous delivery of rotational energy by maintaining more connecting means in an expanding state than in a compressing state, providing efficient power transmission and reducing the need for continuous external power, thus potentially reducing greenhouse gas emissions.
Implementation Method 1
the cam shaft's rotation and the reciprocal movement of the connecting means deliver continuous independent spring force for rotation
Implementation Method 2
A number of rocker arms, one following each cam, are pivotally attached, in a predetermined position, to the apparatus at one end, and which support at an opposite end expansible, compressible connecting means

AI summary
A spring drive motor is presented herein. The motor includes a rotatable cam shaft with a plurality of cams axially spaced there along and rotatable therewith. Each of the cams include a circular shape with at least one portion defined by a linear outer surface. A plurality of rocker arms, each of which correspond with a different one of the plurality of cams, are mounted at one end to a pressure bar assembly and at another end to a power unit. The power unit is defined as comprising an upper spring cup, a lower spring cup and a spring mounted there between. Each upper spring cup is mounted to a crank shaft between adjacently disposed disk-shaped crank members. Lowering the pressure bar assembly engages the rocker arms and activates rotation of the cam shaft and crank shaft through compression and expansion of the springs.
