Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If feedback is generated to provide notifications, then user awareness is improved, but feedback becomes intrusive or inappropriate in different contexts

Engineering Contradiction:

Improveuser awarenessVSAvoidfeedback intrusiveness

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The feedback system dynamically adjusts its characteristics based on detected environmental and device conditions. Sensors monitor context (e.g., ambient light, sound levels, device orientation) and the feedback component modifies notification intensity, type, or timing accordingly, allowing feedback to adapt rather than remain static, thus reducing intrusiveness while maintaining awareness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes feedback parameters such as vibration amplitude, sound volume, or notification timing based on detected conditions. For example, vibration strength is adjusted according to device orientation or ambient noise levels, enabling the same notification to be delivered appropriately across different contexts without being consistently intrusive.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If feedback is adjusted dynamically based on conditions, then feedback appropriateness is improved, but device complexity increases

Engineering Contradiction:

Improvefeedback appropriatenessVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The feedback component serves multiple functions: it provides notifications, adapts to environmental conditions, and responds to device state changes. By making the feedback system multi-functional and integrating sensor data processing directly into the feedback control logic, the patent avoids adding separate complex subsystems while achieving adaptive behavior.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The feedback system uses its own integrated sensors to detect conditions and automatically adjusts its output without requiring external control systems. The feedback component self-regulates based on real-time sensor input, eliminating the need for complex centralized control architecture and reducing overall system complexity.

Inventive Principle:

Principle #25Self-service

3Reliability

If feedback intensity is increased to ensure user awareness, then notification effectiveness is improved, but energy consumption increases

Engineering Contradiction:

Improvenotification effectivenessVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Instead of continuous high-intensity feedback, the system uses periodic or intermittent feedback adjusted to current conditions. Sensors detect context and trigger feedback only when necessary and at appropriate intervals, reducing energy consumption while maintaining notification effectiveness through strategically timed, condition-appropriate feedback bursts.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The feedback intensity parameter is dynamically changed based on detected conditions and battery state. When energy conservation is needed, the system adjusts feedback parameters to use lower intensity modes that still provide adequate notification, balancing effectiveness with energy efficiency rather than maintaining fixed high intensity.

Inventive Principle:

Principle #35Parameter changes

AI summary

The embodiments described herein generally relate to a portable electronic device. The portable electronic device can include a processor and a sensor coupled with the processor, the sensor capable of detecting a stimulus, and responding to the stimulus by providing a detection signal to the processor. The portable electronic device can further include an interface unit capable of interacting with a user. The portable electronic device can further include a feedback unit in communication with the interface unit and the processor, the feedback unit providing a feedback response that is perceptible to the user during the interaction, where when the sensor detects the stimulus, the detection signal provided to the processor by the sensor causes the processor to respond by instructing the feedback unit to alter the feedback response.
