Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy diesel engines and large counterweights are used, then lifting capacity and stability are improved, but fuel consumption and working costs increase significantly
Solution Approach 1:
The patent repositions the counterweight from a large separate mass to a strategically placed center of gravity on the mast itself, located between the front wheels' rotation axis and the mast's upper section. This redistributes the weight more efficiently, reducing the need for excessive counterweights while maintaining stability during lifting operations.
Solution Approach 2:
The patent replaces the traditional internal combustion engine with an electric motor for powering the lifting operation. The electric motor is positioned on the mast and driven by a battery, eliminating the need for heavy diesel engines and associated exhaust systems, thereby reducing fuel consumption and working costs while maintaining lifting capacity.
2Stability of the object's composition
If large counterweights are installed, then stability is improved, but device weight and complexity increase
Solution Approach 1:
The patent integrates the counterbalancing function directly into the mast structure by positioning the center of gravity at a specific location between the front wheels' rotation axis and the mast's upper section. This eliminates the need for separate large counterweight blocks, reducing overall device weight while maintaining stability during lifting operations.
Solution Approach 2:
The patent combines the mast structure with the counterweight function by positioning the center of gravity on the mast itself rather than using separate counterweight components. This merging of functions reduces the number of parts and overall device complexity while achieving the desired stability.
3Power
If traditional internal combustion engines are used, then power delivery is improved, but maintenance requirements and working costs increase
Solution Approach 1:
The patent replaces the internal combustion engine with an electric motor system consisting of a battery-powered motor mounted on the mast. This substitution eliminates complex mechanical components such as exhaust systems, fuel injection mechanisms, and cooling systems, thereby significantly reducing maintenance requirements and working costs while maintaining adequate power delivery for lifting operations.
4Loss of energy
If energy recycling is implemented, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The patent uses an electric motor system that can operate in both motor and generator modes, enabling energy recycling during the lowering phase of lifting operations. The battery-powered motor can capture and store energy during descent, improving overall energy efficiency without requiring complex mechanical energy recovery systems.
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 achieves reduced energy consumption, lower working costs, and easier maintenance and operation by optimizing weight distribution and utilizing a hybrid power system for efficient energy recycling.
Implementation Method 1
the mast of said lifting and lowering means of the load has a respective centre of gravity positioned at, or posteriorly of, the respective rotation axis of the front means, or wheels, for resting and movement of the apparatus
Implementation Method 2
which enable efficient energy recycling as the batteries are not able to rapidly store all the energy of the mast and necessitate, in order to avoid damage, dissipating a part of this recyclable energy
