Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a mains-powered portable cleaning device is used, then continuous power supply is available, but mobility is limited due to the power cable
Solution Approach 1:
The power supply system is segmented into a stationary charging base and a mobile cleaning device. The base remains fixed to provide continuous power, while the cleaning device is divided into modular components including a battery pack that can be independently charged at the base and then detached for mobile operation, resolving the contradiction between continuous power availability and mobility.
Solution Approach 2:
A charging base acts as an intermediary between the mains power supply and the mobile cleaning device. The base stores energy and transfers it to the cleaning device via a battery pack, eliminating the need for a direct power cable connection during mobile operation while ensuring continuous power availability through automated recharging.
2Ease of operation
If a battery pack is integrated into the power tool, then wireless operation is achieved, but weight increases making operation strenuous
Solution Approach 1:
The battery pack is segmented from the main cleaning device body, allowing it to be a separate, interchangeable component. Users can attach only the necessary battery capacity for the task at hand, or swap between different battery packs, thereby achieving wireless operation while minimizing unnecessary weight.
Solution Approach 2:
The battery pack configuration is made dynamic and adaptable. The system allows for different battery pack sizes and capacities to be interchanged based on operational requirements, enabling the device to be lightweight for short tasks while providing extended runtime when needed, thus balancing wireless operation needs with weight constraints.
3Ease of operation
If the battery pack is made lighter for comfort, then handling improves, but operating duration decreases
Solution Approach 1:
The power supply system is segmented into multiple interchangeable battery packs. Users can select lighter battery packs for tasks requiring frequent movement and handling, or switch to heavier, higher-capacity packs for extended stationary operations, thus decoupling the trade-off between handling comfort and operating duration.
Solution Approach 2:
The battery pack system allows for parameter changes in terms of capacity and weight. Different battery packs with varying specifications can be used depending on the operational context, enabling optimization of either handling comfort or operating duration as the primary parameter, rather than being constrained to a fixed compromise.
4Reliability
If a power cable is used for the cleaning device, then power supply is stable, but risk of damage and injury increases in confined spaces
Solution Approach 1:
The power cable is extracted from the operational configuration of the mobile cleaning device. Power is supplied wirelessly or through a detached battery pack during mobile operation, eliminating the physical cable that could cause damage or injury in confined spaces, while power supply stability is maintained through the charging base infrastructure.
Solution Approach 2:
The charging base serves as an intermediary that provides stable power supply without requiring a direct cable connection to the mobile device. Energy is transferred through the base's power system and stored in the device's battery, decoupling the stability provision from physical cable presence and thereby eliminating the associated hazards.
