Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional work vehicles face issues such as heat discomfort for occupants due to engine heat transmission, hindered engine inspection access, increased wiring complexity and cost, and inefficient load carrying platform length changes.
Innovation Solution
Incorporating a radiator-equipped separator to dissipate engine heat, a switchable inspection cover for engine access, and a swing resistance mechanism to maintain load carrying platform position, along with strategic placement of electrical components and cooling systems to isolate them from engine heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the engine is located below the seat, then the vehicle structure is compact, but heat from the engine is transmitted to the foot space causing discomfort to the occupant
Solution Approach 1:
The separator is divided into a first separator and a second separator, creating multiple thermal barriers between the engine and foot space. The first separator is positioned at the front of the engine while the second separator is positioned at the rear, collectively blocking heat transmission pathways and protecting the foot space from engine heat.
Solution Approach 2:
The separator acts as an intermediary thermal barrier between the engine and the foot space. It physically interrupts the heat transmission path, allowing the engine to remain below the seat for compactness while preventing harmful heat from reaching the occupant's foot space.
2Object-affected harmful factors
If a separator is provided to separate the rear seat and engine, then heat from the engine is prevented from reaching the rear seat, but access to the engine side is hindered making inspection work difficult
Solution Approach 1:
The second separator is designed to be movable between a first position (blocking heat) and a second position (allowing access). This dynamic configuration enables the separator to adapt to different operational needs: protecting the rear seat from heat during normal operation, and allowing inspection workers to access the engine area when positioned at the second position.
Solution Approach 2:
The movable second separator is positioned in advance to block heat transmission during normal operation. When inspection is needed, it can be quickly repositioned to provide access, allowing the system to maintain thermal protection while enabling maintenance operations when required.
3Device complexity
If electrical components are located in the vicinity of the engine, then wiring length and complexity are reduced, but the electrical components have a short lifespan due to heat from the engine
Solution Approach 1:
The separator creates distinct thermal zones by positioning electrical components in a space separated from the engine by the first separator. This segmentation allows electrical components to be located near the engine for reduced wiring complexity while the separator maintains a thermal barrier that protects these components from excessive heat, thereby extending their lifespan.
4Adaptability or versatility
If the load carrying platform is made extendable to change length, then adaptability is improved, but the mechanism for changing length becomes more complex
Solution Approach 1:
The load carrying platform incorporates movable sections that can be extended or retracted to change the overall length of the platform. This dynamic configuration allows the platform to adapt to different load requirements while using a relatively simple extension mechanism that slides along guide rails or tracks, minimizing mechanical complexity.
