Solution Overview
Problem
Traditional telehandlers with internal combustion engines face inefficiencies, noise, and pollution issues, which are only partially addressed by hybrid electro-hydraulic systems, necessitating the development of electrical stabilisers for improved performance and sustainability.
Innovation Solution
The design of electrical stabilisers for telehandlers, featuring electric actuators and a control unit that manages the extension and rotation of scissor-type stabilising arms, allowing for efficient operation in both electric and diesel-powered telehandlers, with a focus on eliminating hydraulic components for reduced energy consumption and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If hydraulic actuators are used in traditional telehandlers, then the stabilisers can be actuated reliably, but energy consumption increases and noise is generated
Solution Approach 1:
The patent replaces the hydraulic actuation system with an electric actuation system. Electric motors are used to drive the stabiliser arms instead of hydraulic cylinders, eliminating the need for hydraulic fluid and pumps. This substitution directly reduces energy consumption and noise while maintaining actuation reliability through precise electric motor control.
Solution Approach 2:
The patent eliminates the hydraulic system entirely and replaces it with an electric system. The hydraulic distributor and hydraulic pump are removed, and instead electric motors with direct mechanical transmission are used to actuate the stabilisers, achieving both noise reduction and energy efficiency.
2Object-generated harmful factors
If hydraulic pumps and distributors are used, then stabiliser actuation is achieved, but noise and pollution increase
Solution Approach 1:
The hydraulic system comprising pumps and distributors is replaced with an electric actuation system. Electric motors directly drive the stabiliser mechanisms through mechanical transmission, eliminating noise from hydraulic operations and pollution from hydraulic fluid, while maintaining ease of operation through electric control.
3Loss of energy
If electric actuators are used instead of hydraulic actuators, then energy consumption and noise are reduced, but device complexity may increase
Solution Approach 1:
The patent extracts and removes the complex hydraulic system components (pumps, distributors, hydraulic fluid reservoirs, hoses) and replaces them with simpler electric motor units. This extraction eliminates energy losses associated with hydraulic inefficiencies and reduces overall system complexity despite the introduction of electric components.
