Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed circuit board is used in the moving light, then the hardware is stable and balanced, but the hardware cannot be easily updated or maintained

Engineering Contradiction:

Improvehardware update capabilityVSAvoidretrofit complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The circuit board is designed as a separate, removable module rather than being permanently fixed. This segmentation allows the circuit board to be independently removed and replaced without affecting the rest of the light system, enabling easy hardware updates while maintaining system stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The circuit board transitions from a static fixed state to a dynamic removable state. The board can be easily inserted and removed from the housing, providing flexibility for maintenance and updates while maintaining a stable operational state when installed.

Inventive Principle:

Principle #15Dynamics

2Ease of repair

If the circuit board is made removable for easy updates, then maintenance becomes simpler, but the balance and symmetry of the light may be disrupted

Engineering Contradiction:

Improvecircuit board replacement easeVSAvoidlight balance

Core Design Contradiction:

Ease of repairVSStability of the object's composition

Solution Approach 1:

The circuit board is designed with asymmetric mounting features including offset mounting holes and an off-center position within the housing. This asymmetric placement allows the board to be easily removed and replaced while maintaining the overall balance and symmetry of the light system during operation.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The housing is pre-designed with dedicated mounting structures and balanced positioning for the circuit board. These preliminary design decisions ensure that any replacement board will automatically be positioned correctly to maintain balance, eliminating the need for complex balancing procedures during replacement.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the circuit board is fixed to maintain balance, then the light moves symmetrically, but hardware changes require complex retrofitting

Engineering Contradiction:

Improvelight movement symmetryVSAvoidhardware update ease

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The circuit board is segmented as a separate replaceable module with standardized mounting interfaces. This allows the board to be easily swapped out for different hardware configurations while maintaining the same symmetric position and balance characteristics, simplifying both manufacturing and maintenance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The housing and mounting structure are designed with universal compatibility to accommodate different circuit board configurations. The standardized mounting holes and symmetric positioning allow various hardware versions to be installed while maintaining consistent balance and symmetric light movement characteristics.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A moving light which has a removable part that allows upgrading and retrofitting the moving light, but yet remains balanced. The removable part can be in a balanced location, for example on the center of gravity or center of symmetry of the light. Two separate removable parts can be in different locations, one of which balances out against the other. The parts can be circuit boards, memory chips, processor chips, or digital memory devices such as a type usable in digital cameras.
