Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a mechanical accelerator pedal with acceleration cable is used, then the structure is simple and easy to manufacture, but cable tension changes cause errors in throttle valve operation range and injection pump control

Engineering Contradiction:

Improvestructural simplicityVSAvoidoperation stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces the mechanical acceleration cable system with an electronic sensor-based system. The foot plate's rotational position is detected by a sensor (such as a potentiometer or magnetic sensor) that converts mechanical position into an electrical signal, eliminating the acceleration cable and its tension-related reliability issues while maintaining manufacturing feasibility.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an elastic means (spring) as an intermediary between the foot plate and the sensor. This spring absorbs operational shocks and maintains consistent contact force, ensuring stable sensor readings while protecting the sensor from excessive mechanical stress, thus improving reliability without complicating the overall structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If an electronic accelerator pedal is used to eliminate cable tension issues, then operation feeling is improved and driver fatigue is reduced, but device complexity increases

Engineering Contradiction:

Improveoperation feelingVSAvoidstructural complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the complex mechanical cable tension adjustment system with a simple electronic sensor and elastic means combination. The sensor directly detects foot plate position without mechanical linkages, and the spring provides passive mechanical assistance, significantly reducing structural complexity while improving operation feeling.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The elastic means (spring) is designed to automatically maintain optimal contact force between the foot plate and sensor without requiring external adjustment mechanisms. The spring self-regulates to compensate for wear and environmental changes, eliminating the need for complex adjustment systems and reducing overall device complexity.

Inventive Principle:

Principle #25Self-service

3Loss of energy

If electronic control is implemented to improve fuel efficiency, then fuel consumption rate is improved, but manufacturing cost and economic feasibility become concerns

Engineering Contradiction:

Improvefuel consumption rateVSAvoidmanufacturing cost

Core Design Contradiction:

Loss of energyVSEase of manufacture

Solution Approach 1:

The patent uses a simple electronic sensor (such as a potentiometer or magnetic sensor) instead of complex electronic control systems. This basic sensor technology is cost-effective and easily manufactured, while still enabling precise throttle control that improves fuel consumption rate and achieves economic feasibility.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs inexpensive sensor technologies that are cost-effective for mass production. The simple electronic components used can be easily replaced if needed, and their low individual cost allows for economical manufacturing while still achieving the fuel efficiency improvements necessary for economic feasibility.
