Electronic Device Operation Member Function Allocation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras face challenges in user convenience due to the complexity of managing multiple shooting function items, leading to accidental changes when using a single operation member for multiple settings, which can result in discomfort and inefficiency.
Innovation Solution
An electronic device with a first operation member for changing set values and a second operation member for switching function items allocated to the first, incorporating a registering unit and control unit to manage function item allocation based on an invalid function and the number of registered items, ensuring secure and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple function items are allocated to a single operation member, then the number of operation members can be reduced, but accidental operations may occur and user convenience deteriorates
Solution Approach 1:
The patent applies dynamics by making the allocation of function items to the operation member dynamic rather than static. The control unit changes which function item is allocated to the operation member based on the operation history and the number of registered function items. This dynamic reallocation allows the system to maintain simplicity with one operation member while preventing accidental operations by ensuring that only appropriate functions are accessible at any given time.
Solution Approach 2:
The patent changes the parameter of function item allocation based on the number of registered function items and operation history. When multiple function items are registered, the system switches between different function items allocated to the operation member. This parameter change approach allows the same physical operation member to serve multiple functions safely, resolving the contradiction between device simplicity and operational safety.
2Adaptability or versatility
If function items are switched sequentially among registered items, then customization flexibility is improved, but operation complexity increases when many items are registered
Solution Approach 1:
The patent applies preliminary action by pre-registering multiple function items in advance before actual operation. The registering unit allows users to register desired function items beforehand, and the control unit manages the switching based on this pre-prepared list. This preliminary registration simplifies the operation process during actual use, as users don't need to manually configure or switch between functions during operation - the system handles it automatically based on the pre-registered items.

AI summary
An electronic device includes a first operation member for changing a set value of an allocated function item, and a second operation member for changing a function item allocated to the first operation member, and registers a set of function items to be allocated to the first operation member. The set includes a standard function that is allocated to the first operation member before the second operation member is operated, and the electronic device controls switching among function items to be allocated to the first operation member based on whether the standard function is an invalid function and on the number of function items included in the registered set, the switching being performed in response to an operation performed on the second operation member, the invalid function disabling changing of the set value by the first operation member.
