Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple substrates are used with different reference planes, then the flexibility of design and arrangement of electric components is improved, but the device complexity increases
Solution Approach 1:
The patent divides the substrate system into multiple separate substrates (first substrate, second substrate, third substrate) with different reference planes. Each substrate can be independently designed and arranged according to the specific shape and functionality requirements of the operating device, allowing flexible configuration of electric components without being constrained by a single rigid substrate structure.
Solution Approach 2:
The patent introduces multiple reference planes (first reference plane, second reference plane) that are not parallel to each other, adding spatial dimensionality to the substrate arrangement. This enables electric components to be distributed across different planes and orientations, improving design flexibility and allowing efficient arrangement according to the device's three-dimensional shape.
2Productivity
If substrates are arranged on different reference planes, then the efficiency of component arrangement is improved, but the manufacturing precision requirements increase
Solution Approach 1:
By segmenting the substrate system into multiple independent substrates mounted on different reference planes, the patent allows each substrate to be manufactured and positioned separately. This segmentation enables efficient arrangement of electric components according to the device's shape while managing manufacturing precision through modular assembly rather than requiring high precision in a single monolithic structure.
Solution Approach 2:
The patent introduces a third substrate as an intermediary element that electrically connects the first substrate and the second substrate. This intermediary substrate facilitates the electrical connection between substrates on different reference planes, enabling efficient component arrangement across multiple planes while managing the complexity of inter-substrate connections through a dedicated intermediary structure.
3Adaptability or versatility
If a flexible member is used to electrically connect substrates, then the adaptability of substrate arrangement is improved, but the reliability of electrical connection may worsen
Solution Approach 1:
The patent employs a flexible member (flexible printed circuit board or similar flexible conductor) to electrically connect the first substrate, second substrate, and third substrate. This flexible member allows the substrates to be arranged on different reference planes and orientations according to the device's shape, providing the necessary arrangement flexibility while maintaining electrical connectivity through the flexible conductor's ability to bend and conform to the spatial configuration.

AI summary
An operating device for a human-powered vehicle comprises a base member, an operating member, a first substrate, and a second substrate. The operating member is movably coupled to the base member. The first substrate is provided to one of the base member and the operating member. The second substrate is provided to the one of the base member and the operating member. The second substrate is separate from the first substrate.
