Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharging apparatuses with small electromagnetic generators struggle to achieve high efficiency at low actuation speeds, resulting in insufficient electrical energy generation when the user moves the actuating handle slowly.

Incorporating a spring energy store with a stressing member that is subjected to stress during displacement and then uncoupled to operatively couple with the generator's movable component, ensuring reproducible high-speed movement of the generator's components, thereby increasing electrical energy generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a small electromagnetic generator is used in the discharging apparatus, then the device size is reduced and portability is improved, but the electrical energy generation efficiency becomes insufficient when actuated at low speeds
Solution Approach 1:
The spring energy store is pre-loaded with mechanical energy during the actuation stroke, and this stored energy is then released to drive the generator at high speed. The preliminary action of compressing the spring during actuation ensures that the generator receives sufficient energy input regardless of the actuation speed, resolving the contradiction between small generator size and energy generation efficiency.
Solution Approach 2:
The spring energy store creates a periodic motion pattern where the generator is driven in rapid oscillations as the spring releases its stored energy. This periodic high-speed action ensures that the generator operates in its efficient high-speed range, converting the slow actuation motion into rapid generator rotation that produces sufficient electrical energy.
2Ease of operation
If the user moves the actuating handle slowly, then ease of operation is improved, but the electrical energy generation becomes insufficient
Solution Approach 1:
The spring energy store captures and stores the mechanical energy input during the actuation stroke, regardless of how slowly the user moves the handle. This preliminary energy storage ensures that the subsequent generator operation has sufficient energy available, decoupling the ease of slow operation from the quantity of electrical energy generated.
Solution Approach 2:
The spring energy store acts as an intermediary between the user's slow actuation motion and the generator's required high-speed operation. It mediates the energy transfer by storing energy during slow actuation and releasing it during rapid generator oscillation, ensuring adequate electrical energy generation regardless of actuation speed.
3Use of energy by moving object
If the generator components move at high speed, then electrical energy generation is improved, but the complexity of ensuring reproducible high-speed movement increases
Solution Approach 1:
The spring energy store automatically generates the high-speed motion required for efficient generator operation through its own elastic recovery. The system is self-service in that the spring's natural tendency to return to its un-stressed state provides the driving force, eliminating the need for complex external mechanisms to enforce high-speed movement.
Solution Approach 2:
The complex task of ensuring high-speed generator movement is extracted from the user's actuation action and transferred to the spring energy store. The spring independently handles the speed regulation function, separating the speed control requirement from the user operation and simplifying the overall system complexity.
